Abstract
The purpose of the present invention is to provide a shoe press belt which exhibits improvement in mechanical characteristics such as crack resistance, wear resistance, delamination resistance and bending fatigue resistance, particularly in the surface wear resistance of the shoe press belt and the crack resistance of the bottom regions of water receiving parts. A shoe press belt which is produced by integrating a reinforcing substrate with a polyurethane layer including at least a felt-side layer and in which water-receiving parts are formed in the felt-side layer, wherein the polyurethane equivalent value of the second resin layer including the bottom regions of the water-receiving parts is adjusted so as to be larger than that of the first resin layer including a surface which is to be brought into contact with a felt.
