Abstract
The present invention provides a micro gel particle having a cationic charge, prepared by a radical polymerization. The micro gel particle is obtained in the form of an aqueous dispersion. The micro gel particle dispersion is prepared by dispersing or emulsifying in an aqueous medium (A) a cationic aqueous resin and (B) a resin having at least two polymerizable vinyl groups and a number average molecular weight of 400 to 20,000, followed by radical-polymerizing.
