    摘要： The present invention provides a synthetic leather including at least a substrate (i), an adhesive layer (ii), and a skin layer (iii), in which the adhesive layer (ii) and the skin layer (iii) are formed from respective specific urethane resin compositions. The adhesive layer (ii) is formed from a urethane resin composition including an anionic urethane resin (X) and water (Y). The skin layer (iii) is formed from a urethane resin composition including an anionic urethane resin (S) and water (T), in which the anionic urethane resin (S) is produced using, for example, a polycarbonate polyol (A-1) produced using biomass-derived decanediol.
