    摘要: A laminate comprising a layer formed by melt molding a thermoplastic polyurethane and a fibrous base layer, a film or sheet melt molded from the thermoplastic polyurethane, and a thermoplastic polyurethane composition comprising the thermoplastic polyurethane and tin compound in an amount of 0.3 to 15 ppm (in terms of tin atom) based on the thermoplastic polyurethane; the thermoplastic polyurethane being a thermoplastic polyurethane obtained from a polymeric diol (a) having a number average molecular weight of 1,500 to 4,000, an organic diisocyanate (b) and a chain extender (c) and having an inherent viscosity of at least 0.9 dl/g and a retention of long-chain hard segments when heat melted of at least 80%, the polymeric diol (a) having a crystallization enthalpy (.DELTA.H) of not more than 70 J/g and having low molecular diol units comprising at least 30 mole % of 1,9-nonanediol units. These articles are excellent in resistance to abrasion melting and abrasion and resistance to bleed/whitening and also good in tensile strength and like mechanical properties, durability and cold resistance, as well as softness and flexibility, so that they can be used for leather-like products and other various purposes.
