  The thermosetting powdery coating composition of the invention comprises (A) from 40 to 98 parts by weight of a fluorinecontaining copolymer, which is a copolymer of a fluoroolefin and a comonomer having a crosslinkable reactive group, e.g., hydroxy, carboxyl, amino and glycidyl groups, containing at least 10% by weight of fluorine and having an intrinsic viscosity of 0.05-2 dl/g (30 °C, tetrahydrofuran) and a glass transition temperature of 30-120 °C and (B) from 60 to 2 parts by weight of a curing agent capable of forming crosslinks by reacting with the crosslinkable reactive groups in (A). The powdery coating composition of the invention is excellent in the dispersibility of pigments and efficiency in the coating works therewith and capable of giving a coating film having improved adhesion to the substrate surface, surface luster, impact resistance and insusceptibility to stain.

  本发明的热固性粉状涂料组合物包括 (A) 40 至 98 份（按重量计）的含氟共聚物，它是氟烯烃和具有可交联反应基团（如羟基、羧基、氨基和缩水甘油基）的共聚物，含氟量至少为 10%（按重量计），固有粘度为 0.05-2 dl/g（30℃，四氢呋喃）、(B) 60 至 2 份（按重量计）能与（A）中的可交联反应基团反应形成交联的固化剂。本发明的粉末涂料组合物在颜料的分散性和涂布效率方面都非常出色，能使涂膜与基材表面的附着力、表面光泽、抗冲击性和抗污性得到改善。
