[0037]FIG. 1 is a perspective view showing a configuration according to one embodiment of the present invention. FIG. 2 is an exploded perspective view showing a total configuration according to one embodiment of the present invention. FIG. 3 is a sectional view showing a total configuration according to one embodiment of the present invention.
[0038]Hereinafter, the present invention will be described in detail.
[0039]The present invention includes a decorative plate formed on a lid of a compact case opened at a top thereof and includes a case body 10 accommodating contents, and a case lid 20 hinge-coupled to one side of the case body 10, wherein a decorative plate recess 22 is formed on an upper surface of the case lid 20 and includes a decorative plate 30 mounted and bonded onto the decorative plate recess 22, and the decorative plate 30 includes a transparent plate base 31, a printing layer 32 printed on a bottom of the transparent plate base 31, a pigment layer 33 formed by applying a pigment on a bottom of the printing layer 32, and an adhesive layer 34 formed by applying an adhesive on a bottom of the pigment layer 33.
[0040]The transparent plate base 31 is formed of a transparent synthetic resin material, a phrase or picture printed on a bottom thereof is prevented from being directly exposed to the outside so as to prevent being peeled or erased, thus an additional transparent coating is unnecessary, thereby reducing production costs and allowing long-term use.
[0041]Preferably, the transparent synthetic resin material includes one selected from the group consisting of acryl resin, vinyl acetate resin, vinyl acetyl resin, methyl methacyl resin, polystyrene resin, and celluloid.
[0042]Preferably, a printing layer 32 printed on a bottom of the transparent plate base 31 may include one selected from the group consisting of a pad printing, an offset printing, a screen printing, a transfer printing, and a digital printing.
[0043]The pad printing is a scheme to transfer ink, which is put on an engraved portion of a corrosion plate, onto the transparent plate base 31 by using a silicon pad. Because the silicon pad is used, a printing can be performed on a curved surface as well as a flat surface.
[0044]The offset printing is a printing scheme for expressing all of several tens of million colors the same as seen with eyes. The offset printing is basically formed of four colors, and C.M.Y.K colors are treated into gradation, thus each of the colors is printed in one color, form and texture as same as seen with the eyes. C refers to a blue series, M refers to a red series, Y refers a yellow series, and K refers a black series.
[0045]The screen printing refers to a printing in a manner that a web-shape structure of a fabric formed of a silk or a chemical fiber, and a metal etc. is tightly fastened and used for a screen, a part to be a non-screen image part is covered by a paper stencil or a glue material, and ink is applied on the screen, thus the ink is printed only on a screen image part through the screen.
[0046]The transfer printing refers to a printing in a manner that a print is performed beforehand on a paper applied thereon with special glue, namely, on a transfer paper, and the transfer paper is attached to and peeled from the bottom of the transparent plate base 31 so as to transfer a pattern and a phrase.
[0047]The digital printing does not require an additional film because a digital printer is used. To spontaneously perform printing and coating in the digital printer or to perform an uneven embossing and special intaglio processing is available.
[0048]In addition, preferably, the digital printing uses at least one type of ink selected from the group consisting of aqueous dying ink, aqueous a pigment ink, strong solvent a pigment ink, weak solvent a pigment ink, mild ink, eco ink, and oil ink.
[0049]In addition, according to the digital printing, an image is printed in an ink-jet or a laser type, so that the image can be delicately and clearly to be suitable for a concept of a product.
[0050]Further, in order to emphasize an image of a specific part on an entire print surface, it is preferable to use mixed ink obtained by mixing one of polyester acrylate, epoxy acrylate, and urethane acrylate with palm oil alkyd resin, nonvolatile oil and a pigment.
[0051]The palm oil alkyd resin has low unsaturation due to a low iodine value of about 8 to about 10, thus a dried oxide film is formed, so that a blockage of a nozzle is prevented. In addition, by using palm oil alkyd resin having 20,000 to 40,000 of molecular weight, the gloss and the abrasion resistance of a print surface applied thereon with the mixed ink can be excellent, and the ink dries more rapidly, thus a spread-out, a set-off and so forth are prevented on the applied print surface, thereby implementing a preferable printing.
[0052]Further, a mixed ink composition contains 10 to 15 wt % of the palm oil alkyd resin with respect to 100 wt %, so a color of printed image becomes defected when being under 10 wt % of the palm oil alkyd resin, and a stain is generated on the applied print surface due to low drying speed because of high viscosity of the mixed ink, when being over 10 wt % of the palm oil alkyd resin.
[0053]The pigment layer 33 applied thereon with a pigment is formed at a bottom of the printing layer 32, such that the printing layer 32 can stand out more clearly, and the adhesive layer 34 can be prevented from being seen through the transparent plate, when the decorative plate 30 is bonded into the decorative plate recess 22 on the lid 20.
[0054]In addition, the pigment uses water soluble baking resin a pigment, preferably includes at least one from the group consisting of amino alkyd resin, phenol resin, melamine denatured acryl resin, and amino resin.
[0055]The amino alkyd resin is a baking a pigment formed of a mixture of melamine or urea resin and alkyd resin.
[0056]The melamine denatured acryl resin is a pigment formed of a mixture of melamine resin and thermosetting acryl resin.
[0057]The alkyd resin belongs to polyester resin which is a polymer material generated by condensation of polyvalent alcohol and polyvalent acid.
[0058]In addition, the decorative plate 30 is expressed in various colors by adding a coloring pigment into the pigment, and the decorative plate 30 is expressed in various colors due to light or heat by adding luminous a pigment or cyan a pigment, thereby improving the aesthetic of the decorative plate.
[0059]The adhesive layer 34 formed by applying an adhesive on the bottom of the pigment layer 33 may use an adhesive using rubber cement melt in gasoline or polyvinyl acetate-based polymer melt in thinner as a solution, an adhesive using cyanoacrylate or bisacrylate which is a liquid state having small molecule at first and becomes polymer through polymerization after attachment, or a hot melt adhesive attached by heating and fusing a solid having high molecule, in which the hot melt adhesive is preferably polyester-based polymer.
[0060]A decorative plate formed on a lid of a compact case according to another embodiment of the present invention will be described with reference to FIG. 4.
[0061]FIG. 4 is a sectional view showing a decorative plate formed on a lid of a compact case according to another embodiment of the present invention.
[0062]Hereinafter, the another embodiment of the present invention uses reference numbers the same as the one embodiment.
[0063]The present invention further includes a metal vacuum depositing layer 35 between the printing layer 32 and the pigment layer 33.
[0064]The transparent plate base 31 formed thereon with a printing layer 32 is put into a vacuum chamber, and a metal is vacuum-deposited on the printing layer 32 under the high vacuum condition of 1×10−5 to 1×10−4 torr to form a metal vacuum depositing layer 35.
[0065]The metal vacuum depositing layer 35 preferably includes at least one selected from the metal group consisting of Ti, Al, Au, Ni, Cr, and Cu.

[0069]Preferably, a clear coating composition is sprayed on a top of a transparent plate base 31 so as to form a clear coating layer 36.
[0070]Preferably, the clear coating composition has a three-dimensional web structure and contains silanol which is an ionic bonding of silicon and oxygen.
[0071]The clear coating composition containing the silanol is used to protect an upper surface of the transparent plate base 31 from dusts, sands, and ultraviolet rays and polish the upper surface of the transparent plate base 31.
[0072]Because the clear coating composition contains the silanol (Si—OH), a surface resistance thereof is lower than that of fluororesin, thus static electricity is prevented, and a pollution resistance against urban dusts and discharging gas and cleaning recovery are excellent.
[0073]In addition, ion binding energy between silicon and oxygen of the silanol (Si—OH) is 101 kcal/mol, which is greater than ultraviolet energy having 85 kcal/mol, thus the collapse between molecules due to the ultraviolet rays is prevented, thereby blocking bleach and discoloration.
