Abstract
Disclosed is a micro gel particle having an anionic charge for which it is electrodepositable by itself. The present invention provides a process for preparing an anionic micro gel particle dispersion comprising: PA1 emulsifying in an aqueous medium a resin composition comprising PA2 (A) 100 parts by weight of an anionic film-forming aqueous resin, and PA2 (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 PA1 excepting the combination of an acrylic resin and an alcoxylated methylol melamine; parts by weight being based on the solid content of the resin composition, and PA1 heating the resultant emulsion to above a crosslinkable temperature of said crosslinking agent (B).
