ABSTRACT:
A thermoplastic elastomer laminate comprising: a base fabric, a polyolefin intermediate layer formed on said fabric comprising a polyolefin, at least a part of which is modified by grafting with at least one monomer selected from unsaturated carboxylic acids and derivatives thereof, and a thermoplastic elastomer surface layer formed on said intermediate layer comprising a thermoplastic elastomer. The surface layer is comprised of a composition comprising: a polyolefin resin and an ethylene/alpha-olefin copolymer rubber, in which only said copolymer rubber is, or both said copolymer rubber and at least a part of said polyolefin resin are partially crosslinked. The product is attractive as an artificial leather.
