RESIN COMPOSITION FOR AQUEOUS PAINTS

A resin composition for an aqueous coating composition contains as a main component a cationic resin (U) having a primary hydroxyl group, obtained by reacting (A) a phenol-novolak epoxy resin, (B) a primary or secondary amine compound having a primary hydroxyl group, and (c) a phenol compound having...

Beschreibung
Zusammenfassung:	A resin composition for an aqueous coating composition contains as a main component a cationic resin (U) having a primary hydroxyl group, obtained by reacting (A) a phenol-novolak epoxy resin, (B) a primary or secondary amine compound having a primary hydroxyl group, and (c) a phenol compound having at lest one phenolic hydroxyl group per molecule. The composition has improved water dispersibility, bath stability and pigment dispersibility, and is useful as a cationic electrodeposition coating composition.
