Abstract
A resin composition in which an inorganic-type ultraviolet absorber stand dispersed in a transparent thermoplastic resin, and the ultraviolet absorber has been surface-treated with a surface treating agent selected from a silane coupling agent, a titanium coupling agent and so forth which have an alkoxyl group or a hydroxyl group and an organofunctional group, where the mixing ratio X of the surface treating agent to the inorganic-type ultraviolet absorber is set within the range of 0.05<X<10, and the proportion of content of the inorganic-type ultraviolet absorber in the transparent thermoplastic resin is set within the range of from more than 0.01% by weight to less than 30% by weight.
Claims5
A resin composition which comprises a transparent thermoplastic resin and dispersed therein at least one inorganic-type ultraviolet absorber selected from the group consisting of a titanium oxide, a zinc oxide, a cerium oxide and an iron oxide, wherein;
- said inorganic-type ultraviolet absorber has been surface-treated with at least one surface treating agent selected from the group consisting of a silane coupling agent, a titanium coupling agent, an aluminum coupling agent and a zirconium coupling agent which have an alkoxyl group or a hydroxyl group and an organofunctional group, where the mixing ratio X of the surface treating agent to said inorganic-type ultraviolet absorber (weight of surface treating agent/weight of inorganic-type ultraviolet absorber) is set within the range of 0.05<X<10, and the proportion of content of said inorganic-type ultraviolet absorber in said transparent thermoplastic resin is set within the range of from more than 0.01% by weight to less than 30% by weight.
