Estimating the term…
A thermoplastic skin sheet constituted by (a) a thermoplastic polyolefin or elastomer sheet; (b) a primer layer coated on the sheet, the primer being based on a modified polyolefin resin containing 2 mg-equivalent/g or less of a hydroxyl group or a carboxyl group; and (c) a topcoat layer coated on the primer layer. The topcoat layer may be mainly composed of (a) 100 parts by weight of a polycarbonate polyurethane resin having a number-average molecular weight of 8,000 or more and a 100% modulus of 20 kg/cm2 or more, and (b) 0.1-40 parts by weight of a (meth)acrylate-butadiene-styrene resin. The surface of the topcoat layer may be subjected to embossing.
A thermoplastic skin sheet comprising a thermoplastic sheet made of a thermoplastic polyolefin resin or a thermoplastic elastomer, a modified polyolefin primer layer free from chlorine coated on said sheet, and a topcoat layer coated on said primer layer, said topcoat layer mainly comprising (a) 100 parts by weight of a polycarbonate polyurethane resin having a number-average molecular weight of 8,000 or more and a 100% modulus of 20 kg/cm2 or more, and (b) 0.1-40 parts by weight of a (meth)acrylate-butadiene-styrene resin.
