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.

Method of producing a foamed resin sheet having a three-dimensional pattern or design thereon which comprises applying a heat-foamable plastic material in the form of a two-dimensional pattern on a flexible sheet or web, then heating said heat-foamable plastic material to cause said heat-foamable plastic material to unite with said sheet or web and to expand forming a three-dimensional pattern on said sheet or web and thus form a master mold form, applying a release coating to the three-dimensional surface of said flexible sheet or web, depositing a layer of a foamable resin plastisol upon the surface of said three-dimensional pattern, heating said layer to gel, fuse and foam said layer to form a foamed resin object, and removing said master mold form from said foamed resin object to expose the three-dimensional pattern thereon. Method of producing a resin sheet having a three-dimensional pattern or design thereon which comprises applying a heat-foamable plastic material in the form of a two-dimensional pattern on a flexible sheet or web, then heating said heat-foamable plastic material to cause said heat-foamable plastic material to unite with said sheet or web and to expand forming a three-dimensional pattern on said sheet or web and thus form a master mold form, applying a release coating to the three-dimensional surface of said sheet or web, depositing a layer of fluid non-foaming resin upon the surface of said three-dimensional pattern, curing said layer while said layer is in contact with said three-dimensional surface to form a solid resin article and removing said sheet or web from said fused resin article to expose the three-dimensional pattern thereon.
