    摘要: 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:emulsifying in an aqueous medium a resin composition comprising(A) 100 parts by weight of an anionic film-forming aqueous resin, and(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 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, andheating the resultant emulsion to above a crosslinkable temperature of said crosslinking agent (B).
