Method for producing hollow resin particles
Provided is a method for producing hollow resin particles in which a residual amount of a hydrocarbon solvent once held inside particles in a production process is reduced and particle breakage is suppressed. The method for producing hollow resin particles, which include preparing a mixture liquid containing a polymerizable monomer, a hydrocarbon solvent, a polymerization initiator and an aqueous medium, suspending the mixture liquid to prepare a suspension, subjecting the suspension to a polymerization reaction to prepare a precursor composition containing precursor particles having a hollow portion and including the hydrocarbon solvent in the hollow portion, and removing the hydrocarbon solvent from the precursor particles, wherein the polymerizable monomer contains a crosslinkable monomer in an amount of from 40% by mass to 100% by mass, and wherein the removal of the hydrocarbon solvent is performed by a specific method.
