  The invention relates to a resin composition comprising at least an organophosphorous compound and a branched amorphous carboxylic acid functional polyester, said polyester having a Tg of at least 40° C., said polyester comprising at least 1 to 45% mol of 2,2-dimethyl-1,3-propanediol; a C3 to C5 aliphatic diol AD1 not including 2,2-dimethyl-1,3-propanediol; a C6 to C50 aliphatic or cycloaliphatic diol AD2; 0.1 to 10% mol of an at least trifunctional monomer; 1 to 55% mol of terephthalic acid, wherein the % mol is based on the polyester. The powder coatings of the present invention derived upon curing at low temperature of the thermosetting powder coating compositions of the invention that were storage stable and comprised said resin composition and a crosslinker having functional groups that are reactive with the carboxylic acid groups of the polyester, have limited or no blooming, good smoothness sufficient reverse impact resistance and preferably have also good degassing limit.

  本发明涉及一种树脂组合物，至少包含一种有机磷化合物和一种支链无定形羧酸官能团聚酯，所述聚酯的 Tg 至少为 40°C、所述聚酯包含至少 1% 至 45% mol 的 2,2-二甲基-1,3-丙二醇；不包括 2,2-二甲基-1,3-丙二醇的 C3 至 C5 脂肪族二元醇 AD1；C6 至 C50 脂肪族或环脂族二元醇 AD2；0.1% 至 10% mol 的至少三官能团单体；1% 至 55% mol 的对苯二甲酸，其中 % mol 基于聚酯。本发明的粉末涂料是在本发明的热固性粉末涂料组合物低温固化后得到的，该组合物储存稳定，由所述树脂组合物和具有与聚酯的羧酸基团反应的官能团的交联剂组成，具有有限的发花或无发花、良好的平滑性和足够的反向抗冲击性，最好还具有良好的脱气极限。
