An imitation-leather sheet laminate material is prepared employing an acidic, heat-coagulated, cross-linkable, elastomeric, latex polymer, wherein the acidic latex polymer is coated onto a top, resin, skin layer and a fibrous base sheet is placed on the wet foam layer, which method comprises: shock-heating the wet foam layer to coagulate and cross-link the polymer therein into a fine, open-cell, tough, foam layer and to remove rapidly water from the coagulated foam layer.

Imitation-leather material and method of preparing such material

An imitation-leather sheet laminate material is prepared employing an acidic, heat-coagulated, carboxylated, elastomeric latex polymer, wherein the acidic latex polymer is coated onto a top resin skin layer and a fibrous base sheet is placed on the wet foam layer, which method comprises: shock-heating the wet foam layer to coagulate the carboxylated polymer therein into a fine, open-cell, tough foam layer and to remove rapidly water from the coagulated foam layer.

An imitation leather material comprising a thin layer of a resin film having a decorative top surface, the film bonded to a fabric base layer through an intervening layer of essentially open-cell, carboxylated, elastomeric-cured foam. The foam layer is prepared with a foamable aqueous latex composition having a pH of about 5.0 to 6.5, a viscosity of from about 5,000 to 30,000 cps, and from about 2 to 10 phr of a free acrylic, acid-containing, partially ammonia-neutralized acrylate polymer.
