Abstract

A water-dilutable binder for coatings based on reaction products of diene polymers and poly-unsaturated polyfunctional amidoamines, which comprises (a) a cyclorubber, (b) a polyfunctional amidoamine which has been added to component (a) and is derived from reaction with a monomeric unsaturated fatty acid free from conjugated double bonds but having 12 to 18 carbon atoms or from its oligomers, and (c) a polyisocyanate which is bonded to component (b) and whose isocyanate groups which are not bonded to component (b) are blocked, a process for its preparation and its use for paints and coatings.
