The present invention provides an additive which can improve or improve the light resistance (or whiteness) of a non-fluorinated thermoplastic resin (for example, a super engineering plastic such as an aromatic polyamine, a liquid crystal polyester, or an aromatic polyether ketone resin). This additive includes a fluorine-containing resin and an inorganic white pigment such as titanium oxide. The fluorine-containing resin may be, for example, a fluorine-containing resin having a polymerization component of tetrafluoroethylene, and particularly a tetrafluoroethylene copolymer (for example, a copolymer of tetrafluoroethylene and another fluorinated olefin, tetrafluoroethylene and fluorine). A copolymer of a vinyl ether, at least one selected from the group consisting of a copolymer of tetrafluoroethylene and another fluorinated olefin and a fluorinated vinyl ether). |
