PROBLEM TO BE SOLVED: To provide a synthetic leather which has excellent wear resistance optimal for industrial materials such as a vehicular interior material and an interior material, especially for a sheet for a seat, and in which whitening is not generated.SOLUTION: The synthetic leather is formed by sequentially laminating a skin layer made of a polyurethane resin and a surface treatment layer made of a polyurethane resin on a fibrous substrate. The surface treatment layer contains particles of a copolymer of polyorganosiloxane having a radical polymerizable group at a terminal and (meta) acrylic acid ester. The polyorganosiloxane having a radical polymerizable group at a terminal has a number average molecular weight of 300,000 or more and a copolymerization ratio of the polyorganosiloxane having a radical polymerizable group at a terminal and the (meta) acrylic acid ester is 95:5 to 85:15. |
