Abstract:
An enamel composition comprising:(a) about 50 to 90 weight % of a polyester, based on the total weight of (a) and (b), comprising the reaction products of (1) about 40 to 65 mole % of a diol, based on the total moles of (1), (2), (3), and (4), (2) about 0 to 20 mole % of a polyol, based on the total moles of (1), (2), (3), and (4), (3) about 0 to 25 mole % of a diacid residue, based on the total moles of (1), (2), (3), and (4), (4) about 10 to 60 mole % of an ethylenically unsaturated diacid residue, based on the total moles of (1), (2), (3), and (4), (b) about 10 to 50 weight % based on the total weight of (a) and (b), of an imine-ester crosslinker composition comprising the reaction products of (1) a compound with multifunctional aldehyde groups represented by the formula: â€ƒZâ€”[Râ€”CHO]n wherein Z is a multifunctional residue; R is Ar or alkyl; n is 2 or 3; and (2) an amine with an electron withdrawing group at the &agr; position represented by the formula: H2Nâ€”CH(R)â€”E.W. wherein R is H or alkyl; E.W. is an electron withdrawing group selected from CO2R, CN, COR, Cl, Br, or I; and (c) an organic solvent.
