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.
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.
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.
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).
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.
The amino alkyd resin is a baking a pigment formed of a mixture of melamine or urea resin and alkyd resin.
