Abstract

A thermosetting coating composition containing PA1 A) one or more binders convertible into liquid or dissolved form at least at the curing temperature and containing acidic groups, basic groups or ionic groups of similar charge, PA1 B) one or more binders convertible into liquid or dissolved form at least at the curing temperature and containing basic groups where (A) contains acidic groups, acidic groups where (A) contains basic groups or ionic groups of like charge opposite to the charge of the ionic groups of (A), binder (B) being noninterdiffusible under storage and application conditions, but interdiffusible with binder (A) under hardening conditions, and PA1 C) optionally standard solvents, pigments and/or typical paint auxiliaries and/or additives which do not lead to any interdiffusion of the binders A) and B) under storage and application conditions, and a process for the production of coatings by application of the coating composition and subsequent thermal curing.
