Abstract
The present invention provides a urethane resin composition including an anionic urethane resin (X) and water (Y), in which the anionic urethane resin (X) is produced using, as raw materials, a polycarbonate polyol (A-1) produced using biomass-derived decanediol as a raw material, and a polycarbonate polyol (A-2) produced using a biomass-derived dihydroxy compound having a cyclic ether structure as a raw material. The polycarbonate polyol (A-1) is preferably produced further using butanediol as a raw material. In the polycarbonate polyol (A-1), the molar ratio [(C4)/(C10)] of the butanediol (C4) to the biomass-derived decanediol (C10) is preferably within a range of 50/50 to 98/2.
