PROBLEM TO BE SOLVED: To provide a thermoplastic resin compsn. which can produce a molded article such as a film and a sheet with an excellent elongation at a low stress, a high recovery stress after elongation and an excellent adhesion as well as a small residual deformation after elongation, and a molded article therefrom. SOLUTION: This compsn. is composed of a thermoplastic polyurethane (a) consisting of a polymeric diol unit with an no. average mol.wt. of 500-8,000, an org. diisocyanate unit and a chain extending agent unit and having a nitrogen atom content of <=2.5 wt.%, a thermoplastic polyurethane (b) consisting of a polyesterdiol unit with an no. average mol.wt. of 1,500-5,000, an org. diisocyanate unit and a chain extending agent unit, having a nitrogen atom content of >=2.6 wt.% indicating an endothermic peak at 200-220 deg.C in an differential scanning calorimeter measurement and having a crystallization enthalpy obtd. from the endothermic peak of 2-15 J/g, an ethylene-α-olefin copolymer (c), and a block copolymer composed of an arom. vinyl compd. polymer block and a conjugated diene polymer block and its hydrogenated product (d), and comprises 40-90 wt.% of the component (a), 60-10 wt.% of the component (b), 5-250 wt.% of the component (c) and 5-100 wt.% of the component (d).
