  • Laminates and process for producing the same
    Patent number: 5318649
    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.
    Type: Grant
    Filed: February 16, 1993
    Date of Patent: June 7, 1994
    Assignees: Sumitomo Chemical Company, Limited, Sanvic Incorporation
