Abstract

Binder compositions comprising PA0 (A) copolymers having a molecular weight of from 1500 to 75000 of maleic acid anhydride with other selected olefinically unsaturated monomers, PA0 (B) organic polyamines with aldimine- and/or ketimine-blocked amino groups and, optionally, reaction products containing amide groups of (i) copolymers (A) with (ii) polyamines having free and blocked amino groups, PA0 a process for the production of these compositions by mixing components (A) and (B) and optionally partially blocked polyamines which react with a part of component (A) under formation of component (C) as well as the use of these binder compositions as binder in lacquers, coating compositions or sealing compounds.
