    • The invention relates to a hardenable composition containingA) compounds having at least two activated double bonds (I) based on .alpha.,.beta.-unsaturated carbonyl compounds, .alpha.,.beta.-unsaturated carboxylic acid esters or .alpha.,.beta.-unsaturated nitrile groups,B) compounds containing either at least one primary amino group which is blocked by an aldehyde or ketone having not more than 10 C atoms or at least 2 groups which can be hydrolyzed to NH groups, andC) customary additives, if appropriate catalysts, if appropriate pigments and organic solvents.Either component A or component B or components A and B are based on a branched soluble acrylate copolymer P, which is obtainable by copolymerization ofa) 5 to 30% by weight of monomers having at least two ethylenically unsaturated polymerizable double bonds,b) 5 to 60% by weight of monomers having a functional group andc) 5 to 90% by weight of other ethylenically unsaturated monomers,the sum of a, b and c being 100% by weight.The invention also relates to processes for the preparation of the hardenable composition and its use.
