Abstract
Disclosed is a micro gel particle having a cationic charge, which is electrodepositable. The micro gel particle is obatined in the form of aqueous dispersion. The micro gel particle dispersion is prepared by a process comprising PA0 emulsifying in an aqueous medium a resin composition comprising PA1 (A) 100 parts by weight of a cationic film-forming aqueous resin, and PA1 (B) 10 to 250 parts by weight of a thermosetting crosslinking agent which is self-crosslinked or crosslinked with said aqueous resin (A) in terms of condensation or addition reaction; PA0 parts by weight being based on the solid content of the resin composition, and PA0 heating the resultant emulsion to above a crosslinkable temperature of said crosslinking agent (B).
