The problem to be solved by the present invention is to provide a urethane resin composition, which uses biomass raw materials in a urethane resin composition containing water, and has excellent oil and acid resistance, hand feeling, and stability of the formulated liquid . The present invention provides a urethane resin composition characterized by containing a urethane resin (A) having an anionic group and a nonionic group, a nonionic emulsifier (B), and water (C) The urethane resin (A) uses a polycarbonate polyol (a1) as a raw material, and the polycarbonate polyol (a1) uses a biomass-derived decanediol as a raw material. In addition, the present invention provides a leather sheet characterized in that a coagulated product of the urethane resin composition is present in a fiber base material. Both the urethane resin (A) and the nonionic emulsifier (B) preferably have an oxyethylene group and an oxypropylene group. |
