Abstract

See full text

A method for producing hollow resin particles, the method comprising a mixture liquid preparation step, a suspension preparation step, a polymerization step, and a solvent removal step; wherein a content of a saturated hydrocarbon solvent is 50% by mass or more with respect to 100% by mass of a total amount of a hydrocarbon solvent; wherein a polymerization initiator is an oil-soluble polymerization initiator; and wherein, in the mixture liquid, a crosslinkable monomer contains a tri- or higher functional crosslinkable monomer, and with respect to 100 parts by mass of a total amount of the polymerizable monomer, a total content of the crosslinkable monomer is 80 to 98 parts by mass, a content of the tri- or higher functional crosslinkable monomer is from 10 parts by mass to 98 parts by mass, and a content of the hydrocarbon solvent is from 300 parts by mass to 1500 parts by mass.
