THERMOPLASTIC RESIN COMPOSITION, MOLDED RESIN ARTICLES AND POLARIZER PROTECTING FILM MADE BY USING THR SAME, AND PROCESS FOR PRODUCTION OF THE ARTICLES

摘要

A resin composition comprising a thermoplastic acrylic resin and an ultraviolet absorber (UVA), which has excellent heat resistance due to its high glass transition temperature and which is suppressed in blowing and bleed-out even in high-temperature molding and little suffers from problems resulting from the evaporation of UVA, namely, a thermoplastic resin composition which comprises both a thermoplastic acrylic resin and an ultraviolet absorber having a molecular weight of 700 or above and which has a glass transition temperature of 110°C or above. It is preferable that the ultraviolet absorber have a hydroxy- phenyltriazine skeleton. Further, it is preferable that the acrylic resin have in the backbone chain at least one kind of cyclic structures selected from among lactone ring structure, glutaric anhydride structure, glutarimide structure, N-substituted maleimide structure, maleic anhydride structure, and so on.
