发明名称 TONER FOR COLOR ELECTROSTATIC PHOTOGRAPHY
摘要 PURPOSE:To make compatible light resistance, non-transforming property, transparency by containing a coloring agent obtained by making a polymer having amino group or hydroxyl group on a side chain group to react with a reactive dyestuff. CONSTITUTION:The so called polymer dyestuff obtained by making the polymer having amino group or hydroxyl group on the side chain group of the polymer main chain to react with the reactive dyestuff is used. And the polymer has an unit of styrene derivative or acryl(methacryl)derivative expressed by the formula I or II. In the formula I, II, (n) is 2-3, (m) is 0-2, X is -NH2, -OH and Y is C2nH4nOH, R1 is H, CH3 and R2 is CH3, C2H5. Thus the toner for color electrostatic photography having both light resistance, non-transforming property of pigment and clear color, transparency of dyestuff is obtained low in cost.
