发明名称 Grain leather-like sheet having excellent scratch resistance and abrasion resistance
摘要 A grain-finished leather-like sheet having a fibrous substrate layer, a polyurethane non-porous layer and a polyurethane surface layer which are successively laminated in this order. The polyurethane surface layer contains a binder polyurethane and polyurethane fine particles having a particle size of 1 to 50μm. The total thickness of the polyurethane non-porous layer and the polyurethane surface layer is 150μm or more. The polyurethane surface layer contains the polyurethane fine particles in an amount of 10 to 40 parts by mass per 100 parts by mass of the binder polyurethane. The polyurethane fine particles are not exposed to the surface. The grain-finished leather-like sheet characterized by the above features has a smooth and luster surface, a good hand, and excellent scratch resistance, abrasion resistance and buckling wrinkle resistance. The sheet hardly damages or soils an object which is in contact with its surface by friction.
