ABSTRACT:
Self-crosslinking cationic paint binders based on ureide-modified epoxy resins; the preparation of these binders and their use, particularly in electrodeposition paints, is described. The modification is effected with carboxylic compounds carrying ureide groups, blocked isocyanate groups and, optionally, tertiary amino groups. The carboxylic compounds are obtained through reaction of dicarboxylic acid anhydrides or compounds carrying dicarboxylic acid anhydrides with a substituted urea or a substituted biuret. The products show excellent resistance and adhesion characteristics.
