Kind Code:
B2
Abstract:
The problem to be solved by the present invention is to provide, using a raw biomass material, a water-containing urethane resin composition which is excellent in terms of oleicacid resistance, texture, and mixture liquid stability. The urethane resin composition according to the present invention is characterized by comprising: a urethane resin (A) having an anionic group and a nonionic group and obtained using, as a raw material, a polycarbonate polyol (a1) obtained from a biomass-derived decanediol as a raw material; a nonionic emulsifier (B); and water (C). The present invention further provides a leather sheet characterized by comprising a fibrous base and, present therein, coagulates of the urethane resin composition. It is preferable that the urethane resin (A) and the nonionic emulsifier (B) both have an oxyethylene group and an oxypropylene group.
