ABSTRACT:
Cationic paint binders obtained through reaction of substituted ureas with formaldehyde and phenols are described. The substituted ureas are obtained through reaction of an isocyanate compound carrying at least one free, and optionally also blocked, NCO-group with equivalent quantities of a secondary non-aromatic amine. After partial protonation, the binders are used in water-dilutable paints, particularly in cathodically depositable electrodeposition paints.
