This aqueous dispersion was taken as particulate dispersion 1. The volume average particle diameter of the particulate dispersion 1 measured by a laser diffraction particle size distribution analyzer (LA-9201 available from Shimadzu Corporation) was 120 nm. A part of the particulate dispersion 1 was dried, and the resin therein was isolated. The glass transition temperature (Tg) of the resin was 42° C. and the mass average molecular mass of the resin was 30,000.
