摘要
The invention relates to a process for preparing a binder for electrodeposition coating compositions comprising providing:(A) from 1 to 99.9% by weight of an epoxy resin and(B) from 0.1 to 99.% by weight of a copolymer of vinyl acetate and at least one further component selected from the group vinyl alcohol, alkyl-vinyl acetal and ethylene,characterized in that components (A) and (B) of the binder are mixed intensively in a solvent or in the melt before being used in the coating composition, preferably in the presence of epoxy ring-opening catalysts.
