Publication number: 20100182689Abstract: Provided is a resin composition containing a thermoplastic acrylic resin and an ultraviolet absorber (UVA). While this resin composition has excellent heat resistance because of its high glass transition temperature, foaming and bleed-out can be suppressed and the problems arising from the evaporation of the UVA can be reduced even during the molding of the resin composition at a high temperature. The resin composition is a thermoplastic resin composition containing a thermoplastic acrylic resin and an ultraviolet absorber having a molecular weight of 700 or more, and having a glass transition temperature of 110° C. or higher. It is preferable that the ultraviolet absorber has a hydroxyphenyltriazine skeleton. It is preferable that the acrylic resin has a ring structure in its main chain. The ring structure is, for example, at least one selected from a lactone ring structure, a glutaric anhydride structure, a glutarimide structure, an N-substituted maleimide structure, and a maleic anhydride structure.Type: ApplicationFiled: June 13, 2008Publication date: July 22, 2010Applicant: NIPPON SHOKUBAI CO., LTD.Inventors: Hidetaka Nakanishi, Akio Naka
