Patent ID: 8288006

Claim:
An artificial leather comprising a protective layer comprising a polyurethane resin, a surface layer comprising a polyurethane resin, and a fibrous substrate, successively laminated, wherein the polyurethane resin forming the surface layer is obtained by reacting a urethane polyisocyanate prepolymer (A) and a polyol component (C) containing a urethane polyol prepolymer (B), the urethane polyisocyanate prepolymer (A) is obtained by reacting a polyisocyanate and a polyol in an equivalent ratio (isocyanate groups of polyisocyanate/hydroxyl groups of polyol) of from 2.0 to 6.0, and has a number average molecular weight of from 3,000 to 30,000, the urethane polyol prepolymer (B) is obtained by reacting a polyisocyanate and a polyol containing a polycarbonate polyol in an equivalent ratio (isocyanate groups of polyisocyanate/hydroxyl groups of polyol) of from 0.2 to 0.8, and has a number average molecular weight of from 3,000 to 30,000, an equivalent ratio between the urethane polyisocyanate prepolymer (A) and the polyol component (C) (isocyanate groups of (A)/active hydrogen groups of (C)) is from 1.01 to 2.0, and a weight ratio between the urethane polyisocyanate prepolymer (A) and the polyol component (C) (weight of (A)/weight of (C)) is from 0.7 to 2.0.
