ABSTRACT:
A laminate comprising a soft polyolefin resin layer, an ethylene-unsaturated carboxylic acid ester-maleic anhydride terpolymer resin layer, and a soft urethane foam resin layer is disclosed. The laminate is produced by a process comprising co-extruding a soft polyolefin resin and an ethylene-unsaturated carboxylic acid ester-maleic anhydride terpolymer resin to prepare a two-layer sheet and continuously laminating a soft urethane foam fabricated in a stratiform state on the ethylene-unsaturated carboxylic acid ester-maleic anhydride terpolymer resin layer by hot pressing. The laminate has a satisfactory appearance, toughness, a soft touch, and a cushioning effect.
