NOVELTY - A thermoplastic resin composition comprises 50-94.5 mass parts ethylene-based copolymers (A) chosen from ethylene/ alpha , beta -unsaturated carboxylic acid copolymer, and ethylene, ( alpha ),( beta )-unsaturated carboxylic acid and ( alpha ),( beta )-unsaturated-carboxylic-ester copolymer, 0.5-10 mass parts ternary copolymers (B) which have structural unit derived from alpha -olefin, glycidyl (meth)acrylate, glycidyl unsaturated ether and vinyl ester, or ( alpha ),( beta )-unsaturated carboxylic ester, and 5-40 mass parts polyolefin (C).    USE - Thermoplastic resin composition for molded object used for multilayer material (all claimed). Can also be used for floorings (e.g. flooring for public facilities and residences, industrial flooring, motor vehicles and motor vehicle interior-or-exterior component), electronic materials (e.g. protection film and back-grind film, intermediate film of solar cell sealing material sheet or laminated glass), and building materials (e.g. veneers, timber and plywood, steel plate, wallpaper, furniture and layer sheet of signboard). Molded articles are decorative sheet, strain-resistant sheet or protection sheet, handrail, bag, notebook, dictionary, curtain, partition sheet, industrial sheet, desk mat, tablecloth, mouse pad, marking film, sticker, toy, and stationery articles.    ADVANTAGE - Blocking and melting are hard to produce and shrinkage rate is small.    DETAILED DESCRIPTION - INDEPENDENT CLAIMS are included for:    (1) manufacture of thermoplastic resin composition which involves melt-mixing ethylene-based copolymers (A) chosen from ethylene/ alpha , beta -unsaturated carboxylic acid copolymer, and ethylene, ( alpha ),( beta )-unsaturated carboxylic acid and ( alpha ),( beta )-unsaturated-carboxylic-ester copolymer, ternary copolymers (B) which have structural unit derived from alpha -olefin, glycidyl (meth)acrylate, glycidyl unsaturated ether and vinyl ester, or ( alpha ),( beta )-unsaturated carboxylic ester, and polyolefin (C);    (2) molded object comprising molded thermoplastic resin composition; and    (3) multilayer material comprising single layer or multilayer base material and molded object which are multilayered.
