New electrostatographic toners and developers are provided containing charge-control agents comprising 3,5-di-tertiary-alkyl-4-hydroxybenzenesulfonate salts having the structure:
wherein
R1 and R2 are tertiary-alkyl containing from 4 to 8 carbon atoms; R3, R4, R5 and R6 are the same or different and are independently selected from an unsubstituted alkyl group having from 1 to 24 carbon atoms; a substituted alkyl group having from 1 to 24 carbon atoms substituted with one or more hydroxy-, carboxy-, alkoxy-, carboalkoxy-, acyloxy-, nitro-, cyano-, keto- or halo-groups; a cycloalkyl group having from 3 to 7 carbon atoms; an unsubstituted aryl group having from 6 to 14 carbon atoms; a substituted aryl group having from 6 to 14 carbon atoms substituted with one or more hydroxy-, carboxy-, alkoxy-, carboalkoxy-, acyloxy-, amino-, nitro-, cyano-, keto- or halo-groups; an alkaryl group having from 1 to 20 carbon atoms in the alkyl group and 6 to 14 carbon atoms in the aryl group; an aralkyl group having from 1 to 4 carbon atoms in the alkyl group and 6 to 14 carbon atoms in the aryl group wherein the aryl group may be unsubstituted or substituted with one or more alkyl-, hydroxy-, carboxy-, alkoxy-, carboalkoxy-, acyloxy-, amino-, nitro-, cyano-, keto- or halo-groups; or wherein any two or more of R3, R4, R5 or R6 can be interconnected to one another to form a 5 to 14 membered saturated or unsaturated ring system.
本发明提供了含有电荷控制剂的新型电显影调色剂和显影液,电荷控制剂包括具有以下结构的 3,5-二叔烷基-4-羟基苯磺酸盐:
其中
R1 和 R2 是含有 4 至 8 个碳原子的叔烷基;R3、R4、R5 和 R6 相同或不同,且独立选自具有 1 至 24 个碳原子的未取代烷基;具有 1 至 24 个碳原子的被一个或多个羟基、羧基、烷氧基、羧基烷氧基、酰氧基、硝基、氰基、酮基或卤基取代的取代烷基;具有 3 至 7 个碳原子的环烷基; 具有 6 至 14 个碳原子的未取代芳基; 具有 6 至 14 个碳原子的被一个或多个羟基、羧基、烷氧基、羧基烷氧基、酰氧基、氨基、硝基、氰基、酮基或卤素基取代的取代芳基;烷基中含有 1 至 20 个碳原子、芳基中含有 6 至 14 个碳原子的烷芳基; 烷基中含有 1 至 4 个碳原子、芳基中含有 6 至 14 个碳原子的芳烷基,其中 芳烷基可以未被取代,也可以被一个或多个烷基、羟基、羧基、烷氧基、 碳烷氧基、酰氧基、氨基、硝基、氰基、酮基或卤基取代;或其中任意两个或多个 R3、R4、R5 或 R6 可相互连接,形成 5 至 14 个成员的饱和或不饱和环系统。
