ABSTRACT:
Provided is a process for preparing a decorative plate in which delicate gradation and shadow of a pattern from a photograph or the like can be reproduced with improved sharpness and clarity. The decorative plate has improved adhesive characteristics allowing the pattern forming plating layers to adhere to a substrate with excellent durability.
In the decorative plate, a plating layer is formed so that a desired pattern is formed on a substrate made of stainless steel. The portions other than the plating layer comprise a large number of lines having a predetermined line density. The decorative plate is prepared through a masking step, a plating step and a step of removing a masking layer. The masking process comprises a step of coating a light-sensitive resin on a screen having meshes, curing the light-sensitive resin using a photographic film, mounting the film on the screen and allowing the resin to cure by UV rays. The uncured resin is then removed from the screen, the screen is mounted on a substrate, and an ink layer is formed by a printing process.
