Artificial leather is produced by applying a dope comprising urethane prepolymers containing terminal isocyanate groups, an amine catalyst and a foam stabilizer onto a releasing carrier sheet, exposing the resulting coating layer to a moisture-containing gas under controlled conditions, laminating the coating layer onto a backing material and stripping off the releasing carrier sheet. The resulting artificial leather has a cellular structure of polyurethane microfoam in adhesion with the backing material and an adhesion strength of 100 to 10,000 g/cm of width.

Process for producing artificial leather

A synthetic resin composition which comprises 20 to 50 parts by weight of olefinic resins, 10 to 40 parts by weight of vinyl chloride resins, and 70 to 10 parts by weight of alumina trihydrate having a gibbsite crystal structure whose average particle size is 30 microns at most.
