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 embossed plastic suede material is prepared by the method of embossing under heat and pressure particular areas of a layer of a cellular plastic material characterized by a suede-like surface to provide an embossed surface composed of valley areas and peak areas, the peak areas characterized by a suede-like surface, the cellular structure beneath the valley areas differing from the cellular structure beneath the peak areas and characterized by a higher cell density.

Embossed suede material and method of preparing same

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.
