ABSTRACT:
Water-dilutable paint binders based on acrylates for cathodically depositable paints particularly suited for the formulation of decorative single coats or pale primers are described. The binders are partial condensation products of from 60% to 90% by weight of a hydroxy and amino group containing acrylic copolymer, the basic groups of which were obtained through reaction of glycidyl groups with secondary amines, with 10% to 40% by weight of an oliogomeric or polymeric compound carrying CH-active ester groups, preferably malonic acid ester groups, capable of transesterification or transamidation. The paint films afford particularly good yellowing resistance, detergent resistance, and abrasion resistance.
