PROBLEM TO BE SOLVED: To prepare a dispersion of crosslinked microparticles which, when added to a resin, can be uniformly dispersed in the form of primary particles in the resin. SOLUTION: This dispersion is the one prepared by polymerizing a non- crosslinking monomer (A) with a crosslinking monomer (B) in a solvent (C) in the presence of a polymerization initiator, and then replacing the solvent (C) contained in the dispersion with an organic solvent (E) which has a boiling point higher than that of the solvent (C) and does not dissolve the crosslinked microparticles. |
