PROCESS FOR PREPARING CROSSLINKED RESIN PARTICLES

摘要

Disclosed is an improved process of the post-emulsion method capable of forming crosslinked resin particles which do not have fusion bonds between particles and which have good storage stability and good redispersibility in an aqueous medium. The process comprises (a) dispersing in an aqueous medium a resinous component comprising: (I) a base resin having a glass transition temperature (Tg) of 0.degree.C or less and a polymerizable double bond, (II) a monomer which, when polymerized, provides a resin of which Tg is 20.degree.C higher than that of said base resin, or a resin of which Tg is 20.degree.C higher than that of said base resin, and (III) a polyvinyl compound; (b) bringing about crosslinking inside the dispersed resin particles; and (c) removing the aqueous medium therefrom.
