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.
