The present invention provides a positive-charge control agent containing, as an active substance(s), one or two or more rhodanine compounds represented by the following formula (1).
wherein R1 represents a hydrogen atom, etc.; R2 represents a hydrogen atom, etc.; and R3 to R7, which may be identical to or different from each other, represent a hydrogen atom, a cyano group, a trifluoromethyl group, a nitro group, a linear or branched alkyl group having 1 to 8 carbon atoms which may have a substituent, etc.. R2 to R7 may be joined to each other to form a ring. V, W, X, Y and Z represent a carbon atom or a nitrogen atom and 0 to 3 of V, W, X, Y and Z are nitrogen atoms which have no substituent of R3 to R7, with the proviso that at least one of R3 to R7 is a cyano group, a nitro group, or a linear or branched alkyl group having 1 to 4 carbon atoms substituted with three or more fluorine atoms.
本发明提供了一种正电荷控制剂,其中含有一种或两种或两种以上由下式(1)表示的罗丹宁化合物作为活性物质。
其中 R1 代表氢原子等;R2 代表氢原子等;以及 R3 至 R7(可以彼此相同或不同)代表氢原子、氰基、三氟甲基、硝基、具有 1 至 8 个碳原子且可具有取代基的直链或支链烷基等。R2 至 R7 可相互连接形成一个环。V、W、X、Y 和 Z 代表碳原子或氮原子,V、W、X、Y 和 Z 中的 0 至 3 个为氮原子,它们没有取代 R3 至 R7 的基团,但 R3 至 R7 中至少有一个是氰基、硝基或具有 1 至 4 个碳原子并被 3 个或更多氟原子取代的直链或支链烷基。
