Reaction Steps

To a 50 kgf/cm2 pressure resistant autoclave equipped with a stirrer, methyl methacrylate 200 parts, styrene 150 parts, a cross-linkable monomer constituted by divinyl benzene 5 parts, sodium dodecyl benzenesulfonate 10 parts, ion exchanged water 1200 parts, and a polymerization initiator constituted by azobis butyronitrile 10 parts were charged. The mixture was sufficiently stirred, then was heated to 80° C. to perform the polymerization. Further, after the start of polymerization, when the amount of consumption of the monomer reached 99.8%, the mixture was cooled to stop the polymerization reaction and thereby obtain a latex of the polymer particles D. The obtained latex of the polymer particles D had a solid content concentration of 39%. Note that, polymer particles D are particles which do not have a core-shell structure. Further, the obtained polymer particles D had an average particle size of 190 nm. Next, to the obtained latex of the polymer particles D, decalin: 15,000 parts were added and the particles were sufficiently dispersed. After that, the moisture was removed by drying in vacuo to thereby obtain a decalin dispersion of the polymer particles D. The obtained dispersion had a solid content concentration of 5%.
