An embossed plastic sheet material having a surface design effect thereon, and the process of preparing such material which comprises: applying to compressed areas of an embossed release sheet having a design effect thereon a first polymer characterized by a high modulus of elongation; applying a continuous layer of a second polymer characterized by a low modulus of elongation over the first polymer in the depressed areas; removing the release sheet to provide a polymeric sheet material composed of a continuous layer of a low modulus polymer, with raised areas composed of a high modulus polymer secured thereto, the raised areas of the high modulus polymer forming a substantial part of the sheet surface; and flexing the low modulus polymer in the intervening low areas between the raised high polymer areas to the polymeric sheet to form a weak-hinge effect, thereby providing an imitation leather-type material with an accentuated design effect thereon.

Method of preparing imitation sheet material

An imitation leather material which comprises in combination: a woven fabric base sheet material, one surface of which is a napped surface and the other surface of which is not napped; the napped surface of the base sheet impregnated with a crosslinked polymeric material; the napped impregnated surface of the base sheet characterized by a smooth, buffed, flesh-like surface; an open-cell flexible polymeric foam layer bonded to the other unnapped surface of the base sheet material; a thin polymeric skin layer bonded to the surface of the foam layer; and the thin polymeric skin layer characterized by an imitation leather-like surface.
