ABSTRACT:
Coating compositions which are water soluble or dispersible after basic neutralization comprise the reaction product in the proportion by weight of 90:10 to 10:90 of (1) one or more epoxy resins containing 1 to 2 free oxirane groups, which can be partially esterified by fatty acids, with (2) one or more compounds obtained by the reaction of diene polymerizates with alpha,beta unsaturated carboxylic or dicarboxylic acids or anhydrides, in the presence of an alcoholic moderator solvent. The reaction is conducted at a temperature of at least 130.degree. C.
These coating compositions may contain, if desired, other components such as pigments, partial esters and methylol phenol ethers. They can be applied by roller, spraying, dipping, and are especially adapted for application by electrodeposition, to obtain after curing coatings which are both flexible and hard.
