PURPOSE:To improve moisture resistance and durability and to enhance image quality by treating the suspension polymerized particles obtd. by dispersing a polymer monomer and a coloring agent in an aq. phase contg. a dispersion stabilizer and subjecting the dispersion to suspension polymn. with an org. acid having a specific carbon fluoride group. CONSTITUTION:The suspension polymerized particles obtd. by dispersing the polymer monomer and the coloring agent in the aq. phase contg. the dispersion stabilizer and subjecting the dispersion to the suspension polymn. is treated with the org. acid having the carbon fluoride group expressed by formula I. In the formula I, m=1 to 3, w=1 to 3; RF is CF3(CY2)n [where n=0 to 9; Y is hydrogen or fluorine atom; respectively Y may be the same or different]; Ar is a bivalent arom. hydrocarbon group or arom. hydrocarbon group; X is a carboxy group, sulfonic acid group or hydroxyl group. The moisture resistance and durability are improved in this way and further, the image quality is enhanced. |
