Abstract: A curable powder coating composition comprises (a) a copolymer produced from ai) 5 to 10 wt % of a C1 to C4 alkyl diester of an ethylenically unsaturated dicarboxylic acid, aii) 10 to 45 wt % of a glycidylester of an ethylenically unsaturated carboxylic acid, aiii) 10 to 35 wt % of an alkenyl ester of a branched tertiary carboxylic acid wherein the acid moiety contains nine carbon atoms, and aiv) 0 to 45 wt % of a C1 to C12 alkyl ester of an ethylenically unsaturated carboxylic acid having from 3 to 4 carbon atoms in the acid moiety, the percentages of ai) to av) are relative to the total weight of the polymer adding up to 100%; and (b) a blend comprising (bi) C4 to C16 (cyclo)aliphatic dicarboxylic acid and (bii) a polyester resin having an acid value of from 4500 to 4900 mmole/kg produced from a C5 to C12 branched polyhydroxyalkane and a C4 to C16 (cyclo)aliphatic dicarboxylic acid or anhydride in a polyhydroxyalkane:dicarboxylic acid molar ratio of from 0.2:1 to 0.

Abstract: Linear, carboxylic acid functional polyester resins produced by reaction of: (a) at least one aromatic and/or cycloaliphatic dicarboxylic acid compound A, comprising two aromatic and/or secondary aliphatic carboxyl groups in the 1,2-position, or anhydride thereof; (b) at least one hydroxyl monocarboxylic acid B1, comprising two aliphatic hydroxyl groups, which groups each independently may be primary or secondary hydroxyl groups and wherein the carboxylic acid group is a tertiary carboxyl group, mixed with a cycloaliphatic diol B2 in an amount of at least 5 wt %, relative to the weight of B1 and B2 together; (c) optionally an aliphatic dicarboxylic acid C, comprising an alkylene group having from 3 to 8 carbon atoms and having two terminal aliphatic carboxyl groups; and (d) optionally an aromatic monocarboxylic acid D, the molar ratio of the compounds A:B1+B2:C:D being X:Y+X+Z1:Y:Z2, wherein X ranges from 1 to 8, Y ranges from 0 to 8, Z1 ranges from −3 to 3 and Z2 ranges from 0 to 2,
