<P>PROBLEM TO BE SOLVED: To provide a synthetic leather that has fine grain features close to a natural leather and is excellent in wear resistance, and to provide a simple method for producing the same. <P>SOLUTION: The synthetic leather is provided with an adhesion layer and a surface layer on a substrate in this order. The surface layer has grains on the surface that meet the following requirements (1)-(3) in the cross-sectional shape. (1) In the cross-sectional shape of grains, a curvature radius R of a protrusion and a recess is 0.01 mm-0.30 mm. (2) In the cross-sectional shape of grains, an interior angle of a protrusion is 100°-130°. (3) In the cross-sectional shape of grains, an opening diameter of a recess is 40 μm-100 μm and a depth of a recess is 50 μm-150 μm. <P>COPYRIGHT: (C)2012,JPO&INPIT |
