Polycondensation and/or addition product containing carboxyl groups and tertiary amino groups, coating agents based thereon, and the use thereof

Abstract

A polycondensation and/or addition product containing carboxyl groups and tertiary amino groups, coating agents based on the latter, and the use thereof. The present invention relates to a polycondensation and/or addition product containing carboxyl groups and amino groups. This can be obtained by reacting a) polycarboxylic acids or anhydrides thereof, if appropriate together with monocarboxylic acids, b) polyols, if appropriate together with monools, and, if appropriate c) further modifying components, and, if appropriate, d) a component which is capable of reacting with the reaction product from a), b) and, if appropriate, c), with the proviso that the final product contains tertiary amino groups which originate from components a) and/or b) and/or d), and the reaction product from a), b), if appropriate c) and if appropriate d) and an acid number from 5 to 200, preferably 10 to 130, and an amine number from 3 to 150, preferably 10 to 300. The invention also relates to a process for the preparation of the polycondensation and/or process product, and to coating agents based on the polycondensation and/or addition product, a process for the preparation of the coating agents, and the use thereof for automobile refinishing of automobile bodies and as a topcoat, filler, varnish, primer or undercoat.
