发明名称 ELECTROSTATIC PHOTOGRAPHIC TONER
摘要 PURPOSE:To inexpensively provide the color toner having light resistance, non- migratability, bright color tone property, and transparency by incorporating the coloring agents obtd. by bringing a polymer having a carboxyl group, sulfonyl group, etc., in the side chain group and basic dyes into reaction into the toner. CONSTITUTION:The so-called high-polymer dyes obtd. by bringing the polymer having at least one kind of the carboxyl group, sulfonyl group or the salts thereof the in the side chain group and the acidic dyes into reaction are used as the coloring agents. Particularly this polymer is preferably the polymer contg. the styrene driv., acryl(methacryl) deriv. and ester acryl(methacryl) driv. expressed by formulas I to III as a unit. In the formulas I to III, (n) is 2, 3; (m) is 0 to 2; X is -COOM, -SO2M, -O-(C2H4O)lSO2M, -O-(C2H4O)lCOOM; M is H, Na, K, NH4; l is 1 to 8; R1 is H, CH3; R2 is CH3, C2H5.
