The present invention relates to a polyurethane resin composition comprising a polyol (a1), a reactive silicone (a2) having a number average molecular weight of 4,000 or more and a functional group reacting with an isocyanate group, a reaction product of an urethane resin (A), a polyisocyanate (a3) And an aqueous medium (B). The present invention also provides an aqueous urethane resin composition comprising the aqueous urethane resin composition. The present invention also provides a synthetic leather characterized by having a skin layer and / or a surface treatment layer formed by the aqueous urethane resin composition. A problem to be solved by the present invention is to provide an aqueous urethane resin composition excellent in abrasion resistance and hydrolysis resistance. The aqueous urethane resin composition of the present invention can be suitably used as a skin layer or a surface treatment layer of synthetic leather. |
