ABSTRACT:
Cathodic electrodeposition paints of the type in which a cationically modified epoxy resin is crosslinked with a blocked polyisocyanate crosslinker are disclosed. The paint contains a cationically modified epoxy resin having at least one oxazolidone ring in the molecule and a Tg ranging between 0.degree. C. and 35.degree. C., and a blocked alicyclic polyisocyanate. The use of lead based anticorrosive pigments may be eliminated or substantially reduced. When the alicyclic polyisocyanate is a bicycloalkane polyisocyanate, the use of organic solvent may also be reduced.
