Abstract: The artificial leather of the invention comprises a fibrous sheet material having on the surface thereof a coating formed of at least two layers of polyurethane elastomer with the elasticity modulus E of the layer of the polyurethane elastomer adjacent to the fibrous sheet being lower than the elasticity modulus E.sub.2, E.sub.3 . . . E.sub.p-1 of any of the following layer or layers, and at the same time being lower than the elasticity modulus E.sub.p of the finish layer according to the relationE.sub.1 <E.sub.2 <E.sub.3 < . . . <E.sub.p-1 <E.sub.p,under the condition that all values of the elasticity modulus E are in the range of from 12 to 170 MPa. The method of manufacturing the artificial leather according to the invention is characterized in that the reactive polyurethaneprepolymer, containing free isocyanate -NCO groups, preferably in the range of from 2.2 to 3.2 percent by weight, in admixture with an amine hardening agent of the molar ratio of -NCO groups to -NH.sub.2 groups of from 1.

Abstract: This invention relates to a coating composition which is a mixture of an elastomeric material and a homopolymeric material alone or in admixture with a copolymeric material, the coating having good microporous properties and agreeable "hand" and pliability.

Abstract: A process for the manufacture of artificial leather which has a napped, suede or nubuck surface finish by contacting a natural, synthetic of semi-synthetic backing member with a polymeric system comprising a mixture of a heat-reactive latex and a carboxylated latex and which contains at least one dyestuff. Each of the latices is cross-linked in sequence while the contacted backing member is dried. The migration of non-polymeric components in the system of latices is suppressed during drying. The backing so treated is mechanically altered on the grain side of the backing member to provide an irregular leather-like surface thereto.
