Abstract
Abstract Production of a decorative iridescent cast plastic article comprising a clear cast resin, e.g., polyester, body having embedded therein an embossed multicolored iridescent facsimile on a metal, e.g., aluminum, foil of a multicolored iridescent body, e.g., an abalone shell, the embossed facsimile forming a multicolored iridescent image of the iridescent body in the cast resin, with highlights corresponding to those of the iridescent body, said iridescent cast plastic article being produced by forming color separation negatives from a photographic color transparency of such iridescent body, producing lithographic printing plates from the respective color transparencies, printing the colored image of such iridescent body from said lithographic plates onto a pre-determined area of a metal, e.g., aluminum, foil, embossing into the resulting facsimile on such metal foil, a surface contour bringing out the highlights of the iridescent body, cutting the metal foil embossed iridescent facsimile from the metal foil, and embedding the metal foil embossed iridescent facsimile in a clear casting resin.

Claims Analysis
Total Claims: 15
Claim 1
Independent Claim
32 words
A method as defined in claim 1, including initially coating said multicolored iridescent body with a clear resin to enhance the iridescence of said body prior to said photographing said iridescent body.
Claim 2
Dependent Claim
