Abstract
Synthetic resins which are self-crosslinking under the action of heat have on average two phenolic hydroxyl groups per molecule and are prepared by reacting a reaction product of an epoxy resin and a bifunctional phenol with formaldehyde and a mixture of secondary amines. After they have been protonated with an acid, the resins are suitable as cathodic electrocoating binders.
