Abstract
A cationic electrodeposition coating composition is provided which contains blocked isocyanate curing agent which is blocked with a substance not recognized as a HAPs (hazardous atmospheric pollutant). The cationic electrodeposition coating composition of the present invention contains a cationic group-containing epoxy modified base resin and a blocked isocyanate curing agent, wherein said blocked isocyanate curing agent is obtained by reacting a polyisocyanate compound with, as a blocking agent, a terminal primary OH-containing propylene glycol monoalkyl ether and expressed by the formula RO(CH(CH )CH O) H (where R is an alkyl group having 1 to 8 carbons, which may be branched, and n is 1 to 3).
