Abstract

See full text

Provided is a method for producing a latex comprising hollow resin particles each with a high void ratio and a method for producing hollow resin particles each with a higher void ratio. In the method for producing the latex: a suspension treatment of the mixture liquid which comprises a monomer, a crosslinkable monomer, an oil-soluble polymerization initiator, a fat/fatty oil, a hydrocarbon solvent, a suspension stabilizer and an aqueous medium is carried out to prepare a suspension comprising monomer drops; a polymerization reaction of the suspension is carried out to prepare a precursor composition which comprises precursor particles each having a hollow portion including the hydrocarbon solvent.
