Abstract:
A cationic paint composition containing as resin component a polyol-modified amino group-containing epoxy resin obtained by reacting(a) 60-85% by weight of an epoxy resin with an epoxy equivalent of 180-2,500 with (b) 0.5-15% by weight of an acid compound selected from the group consisting of the phenols of the following formula (1) and the carboxylic acids of the following formula (2), â€ƒwherein, X represents a hydrogen atom or a hydrocarbon group with a carbon atom number 1-15 which may have optionally substituents selected from the group consisting of â€”OH, â€”OR, â€”SH and â€”SR, and Y represents a hydrocarbon group with a carbon atom number 1-15 which may have optionally substituents selected from the group consisting of â€”OH, â€”OR, â€”SH and â€”SR, wherein R represents an alkyl group, (c) 5-20% by weight of a polyol compound obtained by adding a caprolactone (c2) to a compound (c1) containing a plurality of active hydrogen groups, and (d) 5-25% by weight of an amino group-containing compound, the weight ratios being based upon the total solid content weight of the epoxy resin (a), acid compound (b), polyol compound (c) and amino group-containing compound (d).
