ABSTRACT:
The invention relates to surface-coating binders and to their use.
The surface-coating binders, which are substantially free from epoxide groups, are based on a reaction product of (A) a Mannich base obtained from one or more polyhydric phenols which are free from ether groups and contain two or more aromatic rings, and/or one or more monohydric or polyhydric phenols which contain one or more ether groups and contain two or more aromatic rings, one or more secondary amines which contain one or two hydroxyalkyl groups and which may or may not be mixed with secondary dialkylamines or dialkoxyalkylamines, and formaldehyde or a formaldehyde donor, and (B) an epoxy resin, the reaction product of (A) and (B) additionally containing, built into its chemical structure, an olefinically unsaturated alkylphenol of the general formula (I) ##STR1## where R is a radical of 11 to 19 carbon atoms which contains from one to three carbon-carbon double bonds.
These surface-coating binders are used, especially in their protonized form, for the cathodic electrocoating of metal articles.
