Abstract
Abstract Auto-crosslinking, cathodically depositable binders which are water-dilutable upon neutralization comprising the reaction product of: (A) 2 moles of a polyepoxy compound with from 2 to 10 epoxy groups per molecule and an epoxy equivalent of from 100 to 1000; (B) 0.1 to 2.0 moles of a diamine, the nitrogen atoms being secondary-secondary or primary-tertiary; (C) from 1 to 10 moles of an alpha,beta-unsaturated monocarboxylic acid; and (D) from 0.5 to 10 moles of dialkanol amine and/or of a monoalkanol monoalkyl amine, whereby the weight ratios of the components are chosen in order that the sum of the epoxy-reactive hydrogen atoms of components (B) through (D) substantially correspond to the number of epoxy groups of component (A), and the binder contains from 0.5 to 2.5 basic nitrogen atoms and from 0.5 to 2.5 polymerizable double bonds per 1000 molecular weight units. The binders upon heating do not decompose and when employed in coating compositions provide good electrochemical characteristics and good surface qualities.
