PURPOSE:To make the titled composition available for a color toner, and to improve the dispersibility of the titled composition. by incorporating a specific alpha-substed. or unsubstd. amino-epsilon-caprolactam compd. in the titled composition as an electrostatic charge controller. CONSTITUTION:The titled composition contains the alpha-substd. or unsubstd. amino-epsilon-caprolactam compd. shown by the formula as the charge controller. In the formula, R1, R2 and R3 are each hydrogen atom, the substd. or unsubtd. alkyl, aryl, aralkyl or cycloalkyl group, X is an anion. Said compd. displays positive charge ability as the charge controller, and can be used as one component or two components developer. Thus, as the titled composition contains said compd., the suitable color developer is obtd. and the compatibility of the titled composition with a binding resin is improved, thereby obtained the stable electrification of the titled composition. |
