## Abstract

There is provided a method of producing a decorative plate which can be made quite easily without any danger of damage to user's skin. The method comprises the steps of: preparing a base plate having thereon a predetermined design, applying a water-based acrylic paint (water paint of acrylic resin) along a predetermined design to thereby expand the design three-dimensionally, permitting the coated paint to become cured to form a first transparent film portion, applying a water-based acrylic paint on the cured transparent film to thereby further expand the film portion three-dimensionally, and permitting the expanded film portion to become cured to form a second transparent film portion so that a shrinkage of the first transparent film is compensated by the film portion of the second transparent film.

## Claims

### Claim 1

A method of producing a decorative plate comprising the steps of:
preparing a base plate having thereon a design,
applying first water-based acrylic paint on the design to thereby provide a design which is expanded three-dimensionally,
curing the paint to form a first cured transparent film portion,
applying second water-based acrylic paint on the first cured transparent film portion to thereby further expand first cured transparent film portion three-dimensionally, and
curing the further expanded three-dimensional film portion to form a second cured transparent three-dimensional film portion on the design on the base plate,
wherein the water-based acrylic paint is prepared by adding 45 to 50 wt % of water, 0.5 to 1.0 wt % of ammonia. 1.0 wt % or less of anti-forming agent and 2.0 wt % or less of nonionic surface active agent to acrylic copolymerization material dispersions having specific gravity of 1.05 and viscosity of 250-300 cP.

### Claim 2 (depends on 1)

A method of producing a decorative plate according to claim 1, wherein third water-based acrylic paint is applied additionally to the second cured transparent film portion.
