    Abstract: Thermosetting powder compositions comprising as binder a mixture of polyesters containing carboxyl groups and of a crosslinking agent having functional groups capable of reacting with the carboxyl groups.The polyesters comprise:(a) a semicrystalline polyester containing carboxyl groups, which comprises, with respect to the total amount of alcohols, of from 85 to 100 mol % of 1,4-cyclohexanediol and of from 0 to 15 mol % of at least one other aliphatic and/or cycloaliphatic polyol and, with respect to the total amount of acids, of from 85 to 100 mol % of a straight-chain saturated dicarboxylic aliphatic acid having from 4 to 14 carbon atoms and of from 0 to 15 mol % of at least one other aliphatic and/or cycloaliphatic and/or aromatic polycarboxylic acid; and(b) an amorphous polyester containing carboxyl groups, which comprises, with respect to the total amount of acids, of from 70 to 100 mol % of isophthalic acid and of from 0 to 30 mol % of at least one other aliphatic and/or cycloaliphatic and/or aromatic polycarboxylic acid and, with respect to the total amount of alcohols, of from 70 to 100 mol % of neopentyl glycol and/or of 2-butyl-2-ethyl-1,3-propanediol and of from 0 to 30 mol % of at least one other aliphatic and/or cycloaliphatic polyol.
