Abstract

See full text

A resin particle aggregate is the resin particle aggregate formed by aggregating a plurality of resin particles including a polymer of a vinyl monomer, includes 100 parts by mass of the resin particles and 1 to 5 parts by mass of a surfactant. The resin particles are cross-linked by a cross-linkable monomer in an amount of 10 to 50% by mass relative to the total mass of the resin particles, the resin particle aggregate contains an inorganic component in an amount of 0.5% by mass or less, the resin particles have a volume average particle diameter D1, particles contained in a dispersion liquid of the resin particle aggregate in water have a volume average particle diameter D2, and the ratio of D2/D1 is 15 or less.
