Resin microparticles and method for producing same

Abstract

An object is to provide resin microparticles that are made of a general-purpose material and exhibit both high monodispersity and excellent heat resistance, and a method for producing the same. As a solution, the present invention provides resin microparticles obtained by polymerizing vinyl-based monomers, the resin microparticles containing an antioxidant with a melting point of 30° C. or higher and 105° C. or lower and a multifunctional thiol compound and/or a monofunctional thiol compound having an alkyl group having 1 to 9 carbon atoms in the molecule, moreover the resin microparticles having a volume average primary particle size of 0.05 μm or more and 3.0 μm or less, and a coefficient of variation of the volume average primary particle size of 20% or less.
