Abstract
This invention relates to a self-crosslinking binder for coating compositions comprising an aqueously dispersed resinous component A having at least one carbonyl group of the ketone or aldehyde type per molecule, and a component B having at least two hydrazine or hydrazide groups per molecule, and at least one structural unit —NR—NR—CHR—CHR—NH—R(I) where the radicals R, R, Rand Rare each individually selected from the group consisting of a hydrogen radical, and a linear or branched alkyl radical having from 1 to 10 carbon atoms, Rand Rmay additionally be selected from the group consisting of aryl and alkylaryl radicals having from 6 to 15 carbon atoms, and from oxy alkyl radicals with from 1 to 10 carbon atoms, where oxy groups may be inserted into the alkyl chain, or at the end of an alkyl chain, and Ris selected from the group consisting of a hydrogen radical, alkyl radicals which may be linear, branched or cyclic and may have from 1 to 10 carbon atoms, and residues of the formula —(CH)—CO—O—X, where n is an integer of from 1 to 6, and X is the residue of a polyhydric alcohol or phenol, and a process for its preparation.
