Abstract

The invention relates to a self-crosslinking heat-curable binder, in particular for electrocoating finishes, based on an organic synthetic resin which contains primary and/or secondary hydroxyl groups, esterified carboxyl groups and quaternary ammonium groups and can be diluted with water as a result of partial or complete neutralization with acids. The esterified carboxyl groups are activated in the alcohol component by a substituent which has a negative inductive effect.
