Abstract
An object of the present invention is to provide a urethane resin composition for forming a skin layer of a leather-like sheet having a sufficient level of durability, including perspiration resistance and oil resistance, not to result in a poor appearance of the leather-like sheet or peeling of the skin layer from the support over time, for example, when perspiration or oil adheres thereto. The present invention is a leather-like sheet including a skin layer (C) formed from a urethane resin composition containing a urethane resin (A) having two or more hydroxyl groups on at least one end thereof and an aqueous medium (B); an adhesive layer (D); and a support layer (E).
Claims5
