In one form, the present invention provides a synthetic resin leather adhering a base material via an adhesive layer to the back side of a film composed mostly of thermoplastic polyurethane, and the film has on the surface thereof a surface treatment layer formed by coating with a surface treatment agent in which aqueous polycarbonate polyurethane is cross linked by aqueous cross-linking agent containing a carbodiimide group.

Synthetic resin leather and manufacturing method of the same

The present invention provides a surface material which can be replaced to the conventional surface material made of soft polyvinylchloride resin. This surface material is useful for the various uses such as the material for car interior, surface material furniture or the material for porches. The present invention is the urethane resin surface material comprising, a mixed resin sheet composed of 50-95 wt. % thermoplastic polyurethane and 50-5 wt. % of acrylic soft resin and the Shore A hardness of said urethane resin surface material is 60-80. On one side surface of the mixed resin sheet, a layer of knitted, woven, nonwoven fabric or soft foam sheet can be provided. As the thermoplastic polyurethane resin, the thermoplastic polyurethane resin of Shore A hardness 65-90 is desirable, and as the acrylic soft resin, the acrylic soft resin of Shore A hardness 50-80 is desirable.
