ABSTRACT:
Method of producing a three-dimensional pattern on a resin article which comprises producing a two-dimensional pattern on a flexible sheet or web of a heat-foamable plastic material, applying heat to cause said plastic material to expand, thus forming a three-dimensional pattern, applying a release coating to the three dimensional surface of said flexible sheet or web, contacting said three-dimensional surface with a resin plastisol, curing said resin plastisol in contact with said surface to form a solid resin object and removing said flexible sheet or web from said cured resin object to expose the three-dimensional pattern thereon.
