ABSTRACT:
A surface-coating binder which is substantially free from epoxide groups is obtained by reacting Mannich bases, obtained from condensed phenols, secondary amines which contain at least one hydroxyalkyl group, and formaldehyde, with epoxy resins having an epoxide value of from 0.15 to 0.6, which carry blocked isocyanate groups. In the protonized form, the binders may be used for the cationic electrocoating of metal articles.
