PROCESS FOR THE PREPARATION OF PIGMENT PASTE RESINS FOR CATHODICALLY DEPOSITABLE COATING COMPOSITIONS

摘要

The invention relates to a process for the prepar- ation of pigment paste resins for cathodically depositable coating compositions, wherein diepoxide compounds which con- tain polyoxyalkylene structures and alkyl and/or alkylene and/or hydroxyalkyl radicals having more than 3 carbon atoms are first reacted to form epoxy resin/amine adducts and final products with oxazolidine structures are obtained by a partial or complete reaction of secondary amino groups with formaldehyde.
