ABSTRACT:
Carrier resin for pigment pastes, preparation and use thereof The invention relates to paste resins comprising (a) quaternary ammonium groups, (b) hydroxyl groups, (c) urethane radicals and (d) groups of the formula (I) ##STR1## in which R.sup.1 to R.sup.4 independently of one another represent hydrogen or a hydrocarbon radical of 1 to 10 carbon atoms and X denotes hydroxyl or a urethane radical, the average molecular weight (Mn) of these paste resins being 500 to 10,000.
The invention further relates to the preparation of these paste resins, their use for pigment pastes as well as these pigment pastes. Water-thinnable paints, especially electrocoating paints which comprise the pigment pastes according to the invention, furnish, from a variety of substrates, surfaces free from defects and comparable film thicknesses.
