Abstract:
The present invention addresses the problem of providing a urethane resin composition for forming a surface skin layer of a leather-like sheet, said urethane resin composition enabling the formation of the surface skin layer which has an excellent durability, such as perspiration resistance and oil resistance, at such a level that the leather-like sheet shows neither deterioration in appearance nor peeling from a substrate over time even in the case where, for example, sweat, oil or the like sticks thereto. The leather-like sheet according to the present invention is characterized by comprising: a surface skin layer (C) formed by using a urethane resin composition comprising a urethane resin (A) that has two or more hydroxyl groups at least at one end thereof, and an aqueous medium (B); an adhesive layer (D); and a substrate layer (E).
