ABSTRACT:
Cationic epoxy resin esters suitable as binders for stoving coating compositions, particularly for application by electrodeposition, and as mill base resins for grinding pigments and extenders; and a process for producing same is described. The resin esters are produced through reaction of a resinous compound carrying at least two 1,2-epoxy groups with carboxylic acids and, optionally, with primary and/or secondary alkyl- and/or alkanolamines. The carboxylic acid employed, totally or partially, is the reaction product of a dicarboxylic acid anhydride and a tertiary amine which has the structure - ##STR1## wherein R and R.sub.x are a hydrogen atom or an alkyl radical or an aryl radical which may be substituted, R.sub.7 is an alkyl radical, an amino-alkyl radical having the primary amino groups, if present, blocked (as a ketimine) or the moiety remaining after the reaction with an active hydrogen atom of an acrylic or methacrylic monomer monofunctional with regard to the double bond, and wherein n is 2 or 3, the quantity of basic component being chosen in order that the epoxy-free final product has an amine value of at least 35, and preferably of from 40 to 140 mg KOH/g.
