Abstract
Abstract Waterdispersible cationic resins are formed by reacting the components comprising at least (A) an epoxidized polydiene, (B) a bisglycidylether of a polyphenol, (C) an amide compound, which is formed by one or more higher, substantially multiply unsaturated fatty acids and a polyamine and which may comprise a ketimine group or a hydroxy group, and possibly (D) an organic secondary amine and/or (E) a partially and/or fully masked polyisocyanate, which product comprises excess epoxide groups and carbon-carbon double bonds and which resins can be made waterdispersible with an acid under formation of cationic groups. A composite is provided comprising the cationic resin superposed on a conducting substrate and a method is described for forming the composite.
