| 摘要 | The present invention provides an aqueous urethane resin composition including: a urethane resin (A) that is a reaction product of essential ingredients including a polyol (a1), a reactive silicone (a2) having a number average molecular weight of 4,000 or more and having a functional group reactive with an isocyanate group, and a polyisocyanate (a3); and an aqueous medium (B). The present invention also provides a synthetic leather including a skin layer formed from the aqueous urethane resin composition and/or a surface-treated layer formed from the aqueous urethane resin composition. An object of the present invention is to provide an aqueous urethane resin composition excellent in wear resistance and hydrolysis resistance. The aqueous urethane resin composition of the present invention can be suitably used for a skin layer of a synthetic leather and its surface-treated layer. | ||||||
