Patent ID: 11053343

Abstract:
Provided is a thermoplastic resin composition which has improved ultraviolet absorbing capability, mechanical characteristics, hydrolysis resistance, transparency, and blooming resistance and is used for protecting an article used outdoors from ultraviolet light. A problem is solved by a thermoplastic polyurethane resin composition which is 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 and contains an ultraviolet absorber (B1) having a benzotriazole skeleton, an ultraviolet absorber (B2) having a maximum absorption wavelength in a range from greater than or equal to 250 nm to less than or equal to 290 nm and having a triazine skeleton, a hindered amine light stabilizer (C), and an antioxidant (D).
