DETAILED DESCRIPTION OF THE INVENTION
Lenticular Lens
[0023] The lenticular lens used in the present invention refers to
an array of lenses (a lens array) comprising a plurality of
arranged semicylindrical or arcuate and elongated convexes. The
lenticular lens has a convex part surface, on which a plurality of
semicylindrical or arcuate and elongated convexes are arranged in
parallel, and a backside surface which is a surface of the
lenticular lens remote from the convexes. The backside surface is
substantially flat. FIG. 1 is a typical diagram showing a principle
of the formation of a three-dimensional image or a motion picture
by a lenticular lens. Specifically, a lenticular lens 1 has a
surface, on which an array of a plurality of semicylindrical or
arcuate and elongated convexes 2 arranged in parallel, and a
backside surface 3 remote from the convexes 2. The backside surface
3 is substantially flat. An image 4 for the right eye and an image
5 for the left eye are provided preferably in contact with each
other on the backside surface 3. When these images are viewed from
the convex side, the image 4 for the right eye is perceived by the
right eye 6 while the image 5 for the left eye is perceived by the
left eye 7. When the image 4 for the right eye and the image 5 for
the left eye are constructed so as to form parallactic images by
the parallax between the two eye views by a viewer, the viewer
perceives the images as a three-dimensional image. On the other
hand, when two or more types of images, which are preceived
differently depending upon the angle of line of sight, are provided
for the image for the right eye and the image for the left eye,
angle-dependent different images are perceived. In this case, when
these images are brought to continuous images, they are perceived
as a motion picture.
[0024] The recording medium according to the present invention
comprises a layer of this lenticular lens. The lenticular lens
layer may be formed of any material without particular limitation
so far as the function of the lenticular lens is provided.
Preferred materials include resins, for example, PET, PETG, APET,
PP, PS, PVC, acrylic resins, and UV curing resins.
Recording Medium According to First Aspect of Invention
[0025] A recording medium 10 according to the first aspect of the
present invention has a fundamental structure as shown in FIG. 2.
In FIG. 2, an ink absorptive layer 8 is provided on a lenticular
lens layer 1 in its backside surface 3, and an ink permeable layer
9 is provided on the outermost surface of the recording medium 10
remote from the lenticular lens layer 1.
[0026] In the recording medium according to the first aspect of the
present invention, recording is carried out by an ink jet recording
method from the ink permeable layer 9 side which is opposite to the
lenticular lens layer 1. Ink droplets ejected by the ink jet
recording method are deposited onto the ink permeable layer 9, are
permeated through the ink permeable layer 9, reach the ink
absorptive layer 8, and are fixed within the ink absorptive layer
8, preferably the ink absorptive layer 8 in its part very close to
the backside surface 3 of the lenticular lens 1 to form an image.
The image is formed by an ink jet recording method so as to be
perceived as a three-dimensional image or a motion picture through
the lenticular lens. The ink permeable layer 9 has the function of
leading ink droplets to the ink absorptive layer 8 substantially
without the fixation of the ink to the ink permeable layer,
preferably the function of leading the ink droplets very rapidly to
the ink absorptive layer 8. As a result, even immediately after
image recording by an ink jet recording method, any ink does not
stay on the recorded face of the recording medium 10, that is, on
the surface of the ink permeable layer 9, and the image can be
touched by a hand.
[0027] The ink absorptive layer 8 may have any composition without
particular limitation so far as the ink can be fixed, preferably
the ink can be fixed to a part very close to the backside surface 3
of the lenticular lens 1. Preferred materials for the ink
absorptive layer 8 include water absorptive resins such as acrylic
or methacrylic resins, vinyl chloride resins, vinyl acetate resins,
nylons, styrene/acrylic resins, styrene/butadiene resins,
polystyrene/acrylic resins, polystyrene/isoprene resins, methyl
methacrylate/butyl methacrylate resins, melamine resins,
polycarbonate resins, urea resins, epoxy resins, urethane resins,
phenol resins, diallyl phthalate resins, and polyester resins,
particularly preferably cationic water absorptive polymers, for
example, polymers of neutralized salts and quaternized products of
dialkylaminoalkyl (meth)acrylates such as dimethylaminoethyl
(meth)acrylate and diethylaminoethyl (meth)acrtylate, and
dialkylaminoalkyl (meth)acrylamides such as dimethylaminomethyl
(meth)acrylamide and dimethylaminopropyl (meth)acrylamide, and
anionic water absorptive polymers, for example, polymers of
(meth)acrylic acid, 2-acrylamide-2-methylpropanesulfonic acid,
vinylsulfonic acid, styrenesulfonic acid, itaconic acid, maleic
acid, fumaric acid, and arylsulfonic acid.
[0028] The ink absorptive layer 8 may comprise water absorptive or
particle adsorptive inorganic particles. Examples of inorganic
particles include silica, kaolinite, talc, precipitated calcium
carbonate, heavy calcium carbonate, zeolite, alumina, barium
sulfate, carbon black, zinc oxide, zinc sulfate, zinc carbonate,
titanium dioxide, satin white, aluminum silicate, diatomaceous
earth, calcium silicate, aluminum hydroxide, hydrated halloysite,
magnesium carbonate, and magnesium hydroxide. These inorganic
particles are preferably used in combination with a resin as a
binder to form an ink absorption layer. Examples of such binders
include polyester resins, polyurethane resins, polyester urethane
resins, acrylic resins, melamine resins, polyvinyl alcohol resins,
polyvinylpyrrolidones, and methylcelluloses. The inorganic
particles may be mixed with the above water absorptive resin to
form an ink absorptive layer 8.
[0029] The ink permeable layer 9 may be formed of any material so
far as the material has the function of leading ink droplets to the
ink absorptive layer 8. Preferably, the ink permeable layer 9 has a
non-water-absorptive porous structure. This porous structure may be
formed of particles. Examples of such particles include particles
of silica, kaolinite, talc, calcium carbonate, zeolite, alumina,
barium sulfate, carbon black, zinc oxide, titanium oxide, organic
white pigment, benzoguanamine, crosslinked polystyrene, crosslinked
acrylic polymers, and aluminum hydroxide. These particles may be
fixed by a binder to form a porous structure. Examples of binders
usable herein include polyester resins, polyacrylic resins,
polyurethane resins, and various copolymers. Preferred binders
include acrylic resins and acryl-styrene copolymers that have no
significant water absorption.
[0030] In a preferred embodiment of the present invention,
surfactants and the like may be added to the ink permeable layer 9
from the viewpoint of improving and regulating the ink permeation
rate and the like.
[0031] In a preferred embodiment of the present invention, a
recording medium having a white background can be provided by
rendering any one or both of the ink permeable layer 9 and the ink
absorptive layer 8 nontransparent.
[0032] Further, in one embodiment of the present invention, a layer
may be provided between the ink absorptive layer 8 and the ink
permeable layer 9. For example, a layer for enhancing the adhesion
between both the layers may be provided.
[0033] The recording medium according to the first aspect of the
present invention may be produced by dissolving or dispersing the
component(s) for constituting the ink absorptive layer 8 and
optionally the binder, for example, in water or an organic solvent
to prepare a composition, coating the composition onto the backside
surface 3 of the lenticular lens, drying the coating, coating a
composition, prepared by dissolving or dispersing the component(s)
for constituting the ink permeable layer 9 and the binder in a
suitable solvent, for example, water or an organic solvent, onto
the ink absorptive layer 8, and drying the coating.
Recording Medium According to Second Aspect of Invention
[0034] A recording medium 20 according to the second aspect of the
present invention has a fundamental structure as shown in FIG. 3.
In FIG. 3, an ink absorptive layer 21 is provided on a lenticular
lens layer 1 on its backside surface 3. More preferably, an ink
permeable layer 22 is provided on the ink absorptive layer 21, that
is, the surface of the recording medium 20 remote from the
lenticular lens layer 1. Further, an adhesive layer 23 which
surrounds the peripheral part of the recording medium is provided
on the ink permeable layer 22, and also a release sheet 24 is
provided on the adhesive layer 23. As will be described later, in
the recording medium 20 according to the second aspect of the
present invention, ink jet recording is carried out, the release
sheet 24 is then separated, and, in this state, the recording
medium 20 can easily be fixed through the adhesive layer 23 onto a
support such as a wall, a cardboard, or a postcard.
[0035] In the present invention, the provision of the adhesive
layer 23 on a part of the recording medium in its printing side
suffices for the fixation of the recording medium onto a substrate.
When reliable fixation is necessary, as shown in FIG. 3, the
provision of the adhesive layer surrounding the peripheral part of
the recording medium is preferred. Further, in FIG. 3, the adhesive
layer 23 is provided on the ink permeable layer 22. Alternatively,
as shown in FIG. 4, a construction may also be adopted in which the
adhesive layer 23 is provided directly on the lenticular lens 1 in
its adhesive layer forming region and the release sheet 24 is
provided on the adhesive layer 23. In this embodiment, printing by
an ink jet recording method is not substantially carried out in the
part where the adhesive layer 23 has been provided. This part may
be previously colored and subjected to printing of a pattern. In
the recording medium according to the second aspect of the present
invention, as shown in FIG. 5, a plurality of recording media are
connected to each other by easy separation means 25. Examples of
such easy separation means 25 include perforation and incisions to
such a level that can easily cause breaking for separation of the
plurality of recording media from each other.
[0036] The composition of the adhesive layer 23 is not particularly
limited so far as the composition has tackiness high enough to fix
the recording medium to a support. Further, the material for the
release sheet 24 is also not limited so far as the sheet is adhered
to the adhesive layer 23, has strength high enough to avoid the
separation of the adhesive layer during carrying of the recording
medium through an ink jet recording printer, and can easily be
separated in the fixation of the recording medium to a support. For
example, coated paper is preferred.
[0037] As with the recording medium according to the first aspect
of the present invention, in the recording medium according to the
second aspect of the present invention, recording is carried out by
an ink jet recording method from the ink permeable layer 22 side
which is opposite to the lenticular lens layer 1. Ink droplets
ejected by the ink jet recording method are deposited onto the ink
permeable layer 22, are permeated through the ink permeable layer
22, reach the ink absorptive layer 21, and are fixed within the ink
absorptive layer 21, preferably the ink absorptive layer 21 in its
part very close to the backside surface 3 of the lenticular lens 1
to form an image. The image is formed by an ink jet recording
method so as to be perceived as a three-dimensional image or a
motion picture through the lenticular lens. The ink permeable layer
22 has the function of leading ink droplets to the ink absorptive
layer 21 substantially without the fixation of the ink to the ink
permeable layer, preferably the function of leading the ink
droplets very rapidly to the ink absorptive layer 21. As a result,
even immediately after image recording by an ink jet recording
method, any ink does not stay on the recorded face of the recording
medium 20, that is, on the surface of the ink permeable layer 22,
and the image can be touched by a finger.
[0038] The construction and composition in the ink absorptive layer
21 may be the same as those in the ink absorptive layer in the
recording medium according to the first aspect of the present
invention. The construction and composition in the ink permeable
layer 22 may be the same as those in the ink permeable layer in the
recording medium according to the first aspect of the present
invention.
[0039] The recording medium according to the second aspect of the
present invention may be produced by dissolving or dispersing the
component(s) for constituting the ink absorptive layer 21 and
optionally the binder in a suitable solvent, for example, in water
or an organic solvent to prepare a composition, coating the
composition onto the backside surface 3 of the lenticular lens,
drying the coating, coating a composition, prepared by dissolving
or dispersing the component(s) for constituting the ink permeable
layer 22 and the binder in a suitable solvent, for example, water
or an organic solvent, onto the ink absorptive layer 21, drying the
coating, and further providing the adhesive layer 23 and the
release sheet 24 on a part of the ink permeable layer 22.
Recording Medium According to Third Aspect of Invention
[0040] A recording medium 30 according to the third aspect of the
present invention has a fundamental structure as shown in FIG. 6.
In FIG. 6, an ink absorptive layer 31 is provided on a lenticular
lens layer 1 on its backside surface 3. Preferably, an ink
permeable layer 32 is further provided on the ink absorptive layer
31. In the recording medium according to the present invention
temporarily applicable part 33 is further provided. FIG. 7 is an
enlarged view of a temporarily applicable part 33 in the recording
medium according to the present invention. In the embodiment shown
in FIG. 7, the temporarily applicable part 33 is provided as a part
of a transparent sheet 34 provided between the lenticular lens 1
and the ink receptive layer 31. The transparent sheet 34 is larger
than the lenticular lens 1, and the transparent sheet 34 in its
part protruded from the lenticular lens 1 is the part 33. Further,
in a preferred embodiment of the present invention, the part 33 is
connected to the transparent sheet 34 by the easy separation means
35, for example, perforation and incisions to such a level that can
easily cause breaking.
[0041] The recording medium according to the third aspect of the
present invention is in use applied to one side of a sheet having
an adhesive layer on its one or both sides. The sheet having an
adhesive layer on its one or both sides has a fundamental structure
as shown in FIG. 8. In FIG. 8, preferably, a sheet 40 comprises a
sheet 41 having the same size as the recording medium according to
the present invention and a region 42 applicable to the temporarily
applicable part in the recording medium according to the present
invention. The recording medium 30 according to the present
invention is applied to the sheet 40 as follows. The part 33 in the
recording medium 30 according to the present invention is first
temporarily applied onto the part 42 in the sheet 40, and
positioning is then carried out. That is, positioning is carried
out so that the recording medium 30 and the sheet 41 can be
superimposed on top of the other accurately at a predetermined
position. After the positioning, the recording medium 30 is applied
to the sheet 41, and, if necessary, the part 33 in the recording
medium and the part 42 in the sheet 40 are cut away, whereby the
sheet 41 can be well applied to the recording medium. When the
sheet 41 is a postcard or a mount having an adhesive layer on its
one side, the recording medium 30 can be well applied to the
postcard or the mount without misalignment. When the sheet 41 has
an adhesive layer on its both sides, the recording medium 30 can be
further well applied to another support, for example, a mount or a
wall.
[0042] FIG. 9 is an enlarged view of the part 42 or its vicinity in
the sheet 40 shown in FIG. 8 in a preferred embodiment of the
present invention. The sheet 40 comprises a base material sheet 51,
an adhesive layer 52, and a release sheet 53 for protecting the
adhesive layer 52. The part 42 in the sheet 40 comprises an
extended part 51a in the base material sheet 51, an adhesive layer
52a provided on the extended part 51a, and a release sheet 53a for
protecting the adhesive layer 52a. In a preferred embodiment of the
present invention, this part 42 is connected to the sheet 41 by
easy separation means 54, for example, perforation or incision to
such a depth that can easily cause breaking. In the application of
the part 42 to the temporarily applicable part 33 in the recording
medium 30, the release sheet 53a is separated from the sheet 40,
and the part 42 is then temporarily applied to the temporarily
applicable part 33 in the recording medium 30 for positioning, and
the release sheet 53 is separated, followed by the application of
the sheet 42 to the recording medium 30. Thereafter, if necessary,
the part 42 is cut off from the means 54. In a preferred embodiment
of the present invention, as shown in FIG. 9, in the sheet 40, a
construction having an adhesive layer on both sides of the base
material sheet may also be adopted in which an adhesive layer 55
and a release sheet 56 are provided on the other side the base
material sheet 51 remote from the adhesive layer 52 and the release
sheet 53. According to this embodiment, the recording medium 30 can
be well applied to another support, for example, a mount or a
wall.
[0043] In the recording medium in the third embodiment of the
present invention, as shown in FIG. 10, a plurality of recording
media may be connected to each other through easy separation means
61. For the recording medium in this embodiment, preferably, the
sheet having an adhesive layer on its one or both sides is also in
such a form that a plurality of sheets are connected to each other
by easy separation means.
[0044] As with the recording medium according to the first aspect
of the present invention, in the recording medium according to the
third aspect of the present invention, recording is carried out by
an ink jet recording method from the ink permeable layer 32 side
which is opposite to the lenticular lens layer 1. Ink droplets
ejected by the ink jet recording method are deposited onto the ink
permeable layer 32, are permeated through the ink permeable layer
32, reach the ink absorptive layer 31, and are fixed within the ink
absorptive layer 31, preferably the ink absorptive layer 31 in its
part very close to the backside surface 3 of the lenticular lens 1
to form an image. The image is formed by an ink jet recording
method so as to be perceived as a three-dimensional image or a
motion picture through the lenticular lens. The ink permeable layer
32 has the function of leading ink droplets to the ink absorptive
layer 31 substantially without the fixation of the ink to the ink
permeable layer, preferably the function of leading the ink
droplets very rapidly to the ink absorptive layer 31. As a result,
even immediately after image recording by an ink jet recording
method, any ink does not stay on the recorded face of the recording
medium 30, that is, on the surface of the ink permeable layer 32,
and the image can be touched by a finger.
[0045] The construction and composition in the ink absorptive layer
31 may be the same as those in the ink absorptive layer in the
recording medium according to the first aspect of the present
invention. The construction and composition in the ink permeable
layer 32 may be the same as those in the ink permeable layer in the
recording medium according to the first aspect of the present
invention.
[0046] The recording medium according to the third aspect of the
present invention may be produced by dissolving or dispersing the
component(s) for constituting the ink absorptive layer 31 and
optionally the binder in a suitable solvent, for example, water or
an organic solvent to prepare a composition, coating the
composition onto the backside surface 3 of the lenticular lens,
drying the coating, coating a composition, prepared by dissolving
or dispersing the component(s) for constituting the ink permeable
layer 32 and the binder in a suitable solvent, for example, water
or an organic solvent, onto the ink absorptive layer 31, and drying
the coating.
