The invention relates to a resin composition. The resin composition comprises at least an organophosphorous compound and a branched amorphous carboxylic acid functional polyester. The polyester has a Tg of at least 40 DEG C. The polyester comprises at least 1-45 % mol of 2,2-dimethyl-1,3-propanediol; a C3 to C5 aliphatic diol AD1 not including the 2,2-dimethyl-1,3-propanediol; a C6 to C50 aliphatic or cycloaliphatic diol AD2; 0.1-10 % mol of an at least trifunctional monomer; and 1-55 % 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 have limited or no blooming, good smoothness sufficient reverse impact resistance and preferably have also good degassing limit. The thermosetting powder coating compositions are stable in storage and comprise the resin composition and a crosslinker having functional groups that are reactive with the carboxylic acid groups of the polyester.
