ABSTRACT:
Simulated leather materials are described. These are obtained by treating a substrate having a microporous surface film layer by known processes for producing synthetic leathers. The microporous film is obtained by placing a dope containing film-forming polymer, a solvent therefore and an ionizable organic compound on a support and passing the dope bearing support through a coagulation bath under the application of an electric current. The resultant film has a microporous structure made up of open, vertically elongated and uniform cells which imparts a desirable full hand to the leather-like materials made therefrom.
