ABSTRACT:
Polyvinyl chloride articles are chemically embossed by placing a pattern thereon with a composition of vinyl ink containing silicone oil wherein the quantity of silicone oil is from about 2.5% to 5% by weight of the composition and then top coating the article with a fluid coating of an aromatic-hydroxyl functional polyester and a multi-isocyanate curing agent which is cured in the presence of a vaporous tertiary amine catalyst to form an adherent film over said substrate and whereby the fluid coating retracts from over the siliconized ink prior to curing to form a concave pattern on the cured film which is in registry with the siliconized ink.
