Abstract
Powder coating compositions comprising (a) an epoxy resin, (b) at least one polycarboxylic acid of formula I or II
(see fig I and II) wherein R1, R2, R3 and R4 are each independently of one another a hydrogen atom, C1-C4alkyl or the radical -CH2-CH2-COOH, R5 and R6 are each independently of the other a hydrogen atom, C1-C4alkyl, the radical -CH2-CH2-COOH or, when taken together, are an unsubstituted or alkyl-substituted methylene or polymethylene group, each of 1 to 7 atoms, with the proviso that at least two of the substituents R1 to R6 are the radical -CH2-CH2-COOH, the substituents R are each independently of one another a hydrogen atom or the radical
(see fig I and II) wherein R1, R2, R3 and R4 are each independently of one another a hydrogen atom, C1-C4alkyl or the radical -CH2-CH2-COOH, R5 and R6 are each independently of the other a hydrogen atom, C1-C4alkyl, the radical -CH2-CH2-COOH or, when taken together, are an unsubstituted or alkyl-substituted methylene or polymethylene group, each of 1 to 7 atoms, with the proviso that at least two of the substituents R1 to R6 are the radical -CH2-CH2-COOH, the substituents R are each independently of one another a hydrogen atom or the radical
