Abstract:
1. A method of producing a hollow resin particle, having a single hollow structure and an average particle diameter being 10 to 100 nm, which comprises: a step of preparing a dispersion obtained by dispersing a polymerizable droplet containing a species selected from the group consisting of a polyisocyanate, an epoxy prepolymer and an acid halide as lipophilic reaction component A and an organic solvent in a polar medium containing at least one species selected from the group consisting of water, amine, polyol, and polycarboxylic acid as hydrophilic reaction component B; a step of reacting the lipophilic reaction component A with the hydrophilic reaction component B; and a step of removing the organic solvent from the resin particle.
