The present invention provides a thermoplastic resin composition which improves ultraviolet absorbing ability, mechanical properties, hydrolysis resistance, transparency, blooming resistance, and is used for protecting articles for outdoor use from ultraviolet rays. It is solved by this thermoplastic polyurethane resin composition which is an isocyanate component (A1) containing an aliphatic polyisocyanate, a chain extender (A2), and a polyol component (A2) containing a polycarbonate diol having a side chain alkyl group. The reaction product of A3), and comprising: a UV absorber (B1) having a benzotriazole skeleton, a UV absorber (B2) having a triazine skeleton having a maximum absorption wavelength in the range of 250 nm or more and 290 nm or less, hindered Amine light stabilizer (C), antioxidant (D). |
