ABSTRACT:
A producing method of resin particles, which comprises at least an emulsification step of emulsifying a composition containing at least a polymerizable monomer and a polymerization step to form droplets of the composition, and a polymerization step of polymerizing the polymerizable monomer in the droplets to synthesize resin particles, wherein the composition is one selected from Composition A, Composition B, or Composition C:(Composition A): a composition containing a vinyl-based monomer, lactone, a vinyl-based monomer polymerization catalyst for polymerizing the vinyl-based monomer, and a lactone polymerization catalyst for polymerizing the lactone(Composition B): a composition containing a polyester resin, lactone, and a lactone catalyst for polymerizing the lactone(Composition C): a composition containing a vinyl-based monomer, a cyclic keteneacetal compound represented by the following general formula (1), and a radical polymerization initiator(in the general formula (1), R represents a chain or cyclic divalent aliphatic group optionally containing an ether linkage, and the aliphatic group may have a substituent.)
