An object of the present invention is to provide a thermoplastic resin composition for improving ultraviolet absorption ability, mechanical properties, hydrolysis resistance, transparency and bloom resistance and protecting articles used outdoors from ultraviolet rays. A reaction product of an isocyanate component (A1) containing an aliphatic polyisocyanate, a chain extender (A2), and a polyol component (A3) containing a polycarbonate diol having a side chain alkyl group, the benzotriazole skeleton A thermoplastic containing an ultraviolet absorber (B1) having a viscosity, an ultraviolet absorber (B2) having a triazine skeleton having a maximum absorption wavelength in a range of 250 nm to 290 nm, a hindered amine light stabilizer (C), and an antioxidant (D) This is solved by the polyurethane resin composition.
