Description
CROSS-REFERENCE TO RELATED APPLICATIONS
[0001] This application claims priority under 35 U.S.C. .sctn.119
to Korean Patent Application No. 10-2013-0049929 filed on May 3,
2013 in the Korean Intellectual Property Office, the disclosure of
which is incorporated herein by reference in its entirety.
TECHNICAL FIELD
[0002] The following disclosure relates to a nail sticker using a
rear print and a method for manufacturing the same.
BACKGROUND
[0003] As one of modes for expressing physical beauty pursued by
the human being, the cosmetic business is developing faster and
subdivided into various industries. In particular, from the
20.sup.th century, the cosmetic market is rapidly increasing, and
the cosmetic business becomes more popular to the public.
[0004] Generally, in order to improve the shape of the nail, a user
applies a nail polish to perform a nail art in a desired design.
However, the nail art in which a nail polish is applied to the nail
is difficult and cumbersome and takes much time to dry the applied
solution. Further, if a user directly perform the nail art to his
own nail, the shape of the applied nail art is not uniform
depending on whether the user is a right-hander or a
left-hander.
[0005] To solve this problem, a nail shop or the like which
performs the nail art professionally has appeared to decorate the
nail. However, the French nail art performed by a specialist should
be paid each time, which increases the expense. Therefore, a nail
sticker market which allows unskilled persons to easily perform the
nail art is gradually increasing.
[0006] Meanwhile, in a general nail sticker, as disclosed in the
patent literature below, a three-dimensional decoration is formed
on a substrate layer to give the same effect as jewels attached
thereto.
[0007] In addition to the above three-dimensional decoration, as
shown in FIG. 6, light-reflective particles 2 may be added to the
substrate layer 1 to emphasize various kinds of aesthetic senses.
In order to protect the light-reflective particles 2, a top coating
3 may be formed on the upper layer of the light-reflective
particles 2. However, if the top coating 3 is formed on the upper
layer of the light-reflective particles 2, due to the volume and
irregular sizes of the light-reflective particles 2, an unevenness
is formed at the top coating 3, which may cause diffused
reflection, and therefore the twinkling effect of the
light-reflective particles 2 seriously deteriorates.

DETAILED DESCRIPTION OF EMBODIMENTS
[0047] Objects, specific advantages and new features of the present
disclosure will be more apparent from the following detailed
description and embodiments taken in conjunction with the
accompanying drawings. In the specification, when reference
numerals are endowed to components in each drawing, it should be
noted that like reference numerals denote like elements even though
they are depicted in several drawings. In addition, the terms
"first", "second", and the like are used for distinguishing one
component from another, and components are not limited to the
terms. Hereinafter, in a case where detailed description of known
functions or configurations in relation to the present disclosure
is judged as unnecessarily making the essence of the present
disclosure vague, the detailed description will be excluded.
[0048] Hereinafter, preferred embodiments of the present disclosure
will be described in detail with reference to the accompanying
drawings.
[0049] FIGS. 1a and 1b are cross-sectional views showing a nail
sticker using a rear print according to an embodiment of the
present disclosure.
[0050] As shown in FIGS. 1a and 1b, the nail sticker 100 using a
rear print according to this embodiment includes a substrate 110
made of polyurethane, a print layer 120 having light-reflective
particles 125 and directly printed to the substrate 110, an
adhesive layer 130 formed on the print layer 120, and a release
layer 140 formed on the adhesive layer 130. Here, in the nail
sticker 100 using a rear print according to this embodiment, the
print layer 120 having the light-reflective particles 125 is
directed printed to the rear surface of the substrate 110, and the
flat substrate 110 is disposed at the outermost side in a final
stage. Therefore, the deep and shiny feeling and twinkling effect
of the light-reflective particles 125 may be sufficiently
exhibited.
[0051] The substrate 110 gives an area to print the print layer 120
during a manufacturing process, and if being actually adhered to
the nail, the substrate 110 is disposed at the outermost side to
protect the print layer 120. Here, the substrate 110 is made of
polyurethane. The polyurethane has more excellent printing property
in comparison to other materials such as PVC. Therefore, the print
layer 120 may be effectively printed to the substrate 110 made of
polyurethane. Additionally, by performing a surface treatment 115
such as acryl-based primer, urethane-based primer, plasma
treatment, and corona treatment print to one surface of the
substrate 110 to which the layer 120 is printed, the printing
property of the substrate 110 is enhanced, which allows the print
layer 120 having the light-reflective particles 125 to be more
effectively printed. In detail, the acryl-based primer and the
urethane-based primer may enhance the adhering force between the
substrate 110 and the print layer 120 and reinforce the persistency
of the adhesion. In addition, the plasma treatment or the corona
treatment may enhance a surface tension of the substrate 110.
Therefore, the surface tension of the substrate 110 serving as a
target to be adhered increases in comparison to the surface tension
of the print layer 120 serving as an adhesion target and thus
improves wettability, which allows the print layer 120 to be
effectively adhered and printed to the substrate 110.
[0052] The print layer 120 plays a role of substantially giving an
aesthetic feeling at the nail sticker 100. Here, the print layer
120 may be directly printed to the substrate 110. At this time, the
print layer 120 may be printed to the substrate 110 by using a roll
coater, a bar coater, or a screen printing. In addition, the print
layer 120 includes light-reflective particles 125 which reflect
light. At this time, the print layer 120 may be formed by mixing
the light-reflective particles 125 with any one of acryl-based
resins, urethane-based resins, and combinations thereof, and the
light-reflective particles 125 may be mixed with any one of the
acryl-based resins, the urethane-based resins, and combinations
thereof by means of screen printing, scattering, or spraying. Here,
the light-reflective particles 125 include glitter, bling, spangle,
confetti, or pearl and have a predetermined volume. Since the
light-reflective particles 125 have a predetermined volume as
described above, if the print layer 120 having the light-reflective
particles is printed to the front surface of the substrate 110,
instead of rear printing, the twinkling effect of the
light-reflective particles 125 may deteriorate. In detail, if the
print layer 120 is printed to the front surface of the substrate
110 and a top coating is formed at the outermost side to protect
the print layer 120, an unevenness is formed at the top coating due
to the volume and irregular sizes of the light-reflective particles
125. Therefore, diffusion reflection occurs, which seriously
deteriorates the twinkling effect of the light-reflective particles
125. However, in the nail sticker 100 using a rear print according
to this embodiment, the print layer 120 having the light-reflective
particles 125 is printed to the rear surface of the substrate 110,
and the substrate 110 is disposed at the outermost side in a final
stage. As a result, since the flat substrate 110 is disposed at the
outermost side, regular reflection occurs (see the arrow of FIG.
1a) instead of diffused reflection, and so the deep and shiny
feeling and twinkling effect of the light-reflective particles 125
may be sufficiently realized.
[0053] The adhesive layer 130 plays a role of adhering the nail
sticker 100 to the nail and is formed on the print layer 120. Here,
the adhesive layer 130 may be made of pressure sensitive adhesive
(PSA), without being limited thereto. The PSA is a decompressing
adhesive material which applies an adhesive force when a pressure
is applied thereto for the adhesion to the nail.
[0054] The release layer 140 plays a role of protecting the
adhesive layer 130 until the nail sticker 100 is adhered to the
nail, and is formed on the adhesive layer 130. Here, the material
of the release layer 140 is not specially limited if it may be
easily separated from the adhesive layer 130 for the convenience of
the user, but the release layer 140 may be made of, for example,
any one of polyethylene terephthalate (PET), polypropylene (PP),
and combinations thereof, which is matt-treated at a surface
thereof opposite to the surface contacting the adhesive layer 130.
As described above, by matt-treating the release layer 140, it is
possible to give a slipping property. Therefore, during the
manufacturing process, the release layer 140 may effectively pass
through an automatic printing machine or the like, and it is
possible to prevent release layers 140 of adjacent products from
being adhered to each other.
[0055] In addition, as shown in FIG. 1b, at a surface of the
substrate 110 opposite to the surface thereof to which the print
layer 120 is printed, a three-dimensional decoration 160 may be
formed to protrude. Here, the three-dimensional decoration 160 may
be formed with limestone or transparent paint having a jewel shape.
By forming such a three-dimensional decoration 160, it is possible
to give an aesthetic feeling as if an actual jewel is attached.
[0056] FIGS. 2a and 2b are perspective views for illustrating a
process of using the nail sticker using a rear print according to
an embodiment of the present disclosure.
[0057] As shown in FIGS. 2a and 2b, in the nail sticker 100 using a
rear print according to this embodiment, after the release layer
140 is removed (see FIG. 2a), the adhesive layer 130 is adhered to
the nail (see FIG. 2b). In this case, the adhesive layer 130, the
print layer 120, and the substrate 110 are disposed in order from
the nail. In other words, the flat substrate 110 is disposed at the
upper side of the print layer 120 having the light-reflective
particles 125. As described above, since the flat substrate 110 is
disposed at the upper side of the print layer 120, diffused
reflection does not occur, and accordingly the deep and shiny
feeling and twinkling effect of the light-reflective particles 125
may be sufficiently realized.
[0058] Meanwhile, FIG. 3 is a cross-sectional view showing a nail
sticker using a rear print according to another embodiment of the
present disclosure.
[0059] As shown in FIG. 3, a binder layer 150 may be additionally
formed between the adhesive layer 130 and the print layer 120.
Here, the binder layer 150 plays a role of preventing an unevenness
from being generated at the adhesive layer 130 by the
light-reflective particles 125 included in the print layer 120. In
detail, if the adhesive layer 130 is directly formed on the print
layer 120 having the light-reflective particles 125, an unevenness
may be generated at the adhesive layer 130 due to a volume or
irregular sizes of the light-reflective particles 125. The
unevenness of the adhesive layer 130 deteriorates the adhesion to
the nail as well as bends the nail sticker 100 and deteriorates the
flatness of the substrate 110 as a whole, which may deteriorate
deep and shiny feeling and twinkling effect of the light-reflective
particles 125. However, if the binder layer 150 is added between
the adhesive layer 130 and the print layer 120, the binder layer
150 absorbs the volume or irregular sizes of the light-reflective
particles 125, thereby preventing the flatness of the substrate 110
from deteriorating.
[0060] FIG. 4 is a cross-sectional view for illustrating a method
for manufacturing a nail sticker using a rear print according to an
embodiment of the present disclosure, according to a process
order.
[0061] As shown in FIG. 4, a method for manufacturing a nail
sticker 100 using a rear print according to this embodiment
includes (A) printing a print layer 120 having light-reflective
particles 125 to a substrate 110 made of polyurethane, (B) forming
an adhesive layer 130 on the print layer 120, and (C) forming a
release layer 140 on the adhesive layer 130.
[0062] First, as shown in FIG. 4a, the substrate 110 is prepared.
Here, the substrate 110 is made of polyurethane with an excellent
printing property. In addition, in order to further reinforce the
printing property of the substrate 110, a surface treatment 115
such as acryl-based primer, urethane-based primer, plasma
treatment, and corona treatment print may be performed to one
surface of the substrate 110 to which the layer 120 is printed.
[0063] Next, as shown in FIG. 4b, the print layer 120 is printed to
the substrate 110. Here, the print layer 120 may be printed by
using a roll coater, a bar coater, or a screen printing. In
addition, the print layer 120 may be made of any one of acryl-based
resins, urethane-based resins, and combinations thereof, and the
light-reflective particles 125 may be mixed to the print layer 120.
At this time, the light-reflective particles 125 may be mixed with
any one of the acryl-based resins, the urethane-based resins, and
combinations thereof by means of screen printing, scattering, or
spraying. Meanwhile, the light-reflective particles 125 include
glitter, bling, spangle, confetti, or pearl and have a
predetermined volume.
[0064] In this step, since the print layer 120 is printed to the
rear surface of the flat substrate 110 and the substrate 110 is at
the outermost side in a final stage (see FIG. 4e), the volume or
irregular sizes of the light-reflective particles 125 included in
the print layer 120 does not give an influence on the flatness of
the outermost member (the substrate 110). Therefore, diffused
reflection does not occur, and thus the twinkling effect of the
light-reflective particles 125 may be sufficiently realized, as
described above.
[0065] Next, as shown in FIG. 4c, the adhesive layer 130 is formed
on the print layer 120. Here, the adhesive layer 130 is finally
adhered to the nail and may be made of, for example, PSA.
[0066] Next, as shown in FIG. 4d, the release layer 140 is formed
on the adhesive layer 130. Here, the release layer 140 protects the
adhesive layer 130, and for example, the release layer 140 may be
made of, for example, any one of polyethylene terephthalate (PET),
polypropylene (PP), and combinations thereof, which is matt-treated
at a surface thereof opposite to the surface contacting the
adhesive layer 130.
[0067] Next, as shown in FIG. 4e, the three-dimensional decoration
160 is formed on an exposed surface of the substrate 110. Here, the
three-dimensional decoration 160 may be formed with limestone or
transparent paint having a jewel shape. However, this step is
optional and may be excluded.
[0068] Meanwhile, FIG. 5 is a cross-sectional view for illustrating
a method for manufacturing a nail sticker using a rear print
according to another embodiment of the present disclosure,
according to a process order.
[0069] The method for manufacturing a nail sticker 100 using a rear
print as shown in FIG. 5 is substantially identical to the method
for manufacturing a nail sticker 100 using a rear print as shown in
FIG. 4, until the step of forming the print layer 120 on the
substrate 110 (see FIGS. 5a and 5b).
[0070] However, as shown in FIG. 5c, before the step of forming the
print layer 120 and the step of forming the adhesive layer 130, a
step of forming a binder layer 150 on the print layer 120 may be
added. Here, the binder layer 150 may be made of any one of
acryl-based materials, urethane-based materials, silicon-based
materials, epoxy-based materials, and combinations thereof. In
addition, the binder layer 150 absorbs the volume or irregular
sizes of the light-reflective particles 125 included in the print
layer 120. In other words, the binder layer 150 plays a role of
leveling the print layer 120. Therefore, as shown in FIG. 5d, even
though the adhesive layer 130 is formed on the binder layer 150, an
unevenness is not generated at the adhesive layer 130, which may
prevent the nail sticker 100 from being bent as a whole. Meanwhile,
after the adhesive layer 130 is formed on the binder layer 150, as
shown in FIG. 5e, the release layer 140 may be formed on the
adhesive layer 130, and as shown in FIG. 5f, the three-dimensional
decoration 160 may be formed on an exposed surface of the substrate
110.
[0071] While the present invention has been described with respect
to the third embodiment, this is just for illustrating the present
disclosure in detail, and the present disclosure is not limited
thereto. It will be apparent to those skilled in the art that
various changes and modifications may be made without departing
from the spirit and scope of the present disclosure.
[0072] Simple changes or modifications of the present disclosure
belong to the scope of the present disclosure, and the protection
range of the present disclosure will be apparent from the appended
claims.
