Abstract: Poromeric artificial leather is produced by (1) impregnating a textile sheet with an aqueous polyurethane (PU) dispersion and drying to form an essentially nonporous material and (2) treating the impregnated material with an aqueous solution of a Bronsted base. An Independent claim is also included for poromeric artificial leather obtained by this process.

Abstract: A process for producing poromeric synthetic leather comprises I. producing an essentially nonporous impregnate by impregnating a textile sheet material with an aqueous polyurethane dispersion and drying, and II. producing a poromeric synthetic leather from the impregnate by subjecting the impregnate to the action of an aqueous solution of a Bronsted base.
