PURPOSE:To provide a sheet having excellent design effect displaying the color of the lower coating layer through the upper layer, by coating the surface of a sheet substrate containing a polymeric elastomer successively with a coating layer containing a pigment, etc. and with a porous coating layer, and breaking a part of the porous structure of the porous coating layer. CONSTITUTION:The surface of a sheet substrate prepared by impregnating and/or coating a polyurethane elastomer, etc. to a fibrous substrate such as nonwoven cloth, etc. is coated with (A) a coating layer composed of a polyurethane elastomer containing pigment and/or dye, and then with (B) a coating layer composed of a polyether-type polyurethane elastomer having an apparent density of 0.35-0.55g/cm<3> and a thickness of 0.1-6.5mm. The layer B has a porous structure masking the color of the layer A and turns transparent to display the color of the layer A when the porous structure is broken with heat. The product is topped with a coating layer C having a thickness of 0.5-100mu to improve the abrasion strength. A sheet having excellent abrasion resistance and design effect can be produced by this process.
