    • PROBLEM TO BE SOLVED: To provide a toner that exhibits good start-up of electrification and can reproduce stable images for an extended period of time without being affected by temperature or humidity even if development is repeated in continuous use.SOLUTION: A charge control agent contains a metal complex salt compound represented by the general formula (1), and is controlled to have an electric conductivity of 110 μS/cm or lower when the compound of 1 wt.% is dispersed in an ion exchanged water. Toner for developing electrostatic charge image containing the charge control agent is also provided. In the formula, M represents a coordination center metal such as Fe; Ar represents a substituted or unsubstituted aryl group; X and Y represent -O- or the like; and Krepresents a sodium ion or the like or may be a mixture thereof; m represents 1, 2, 3 or 6; p represents a valence of the metal M; n represents 1, 2 or 4; and q represents 0 or an integer.
    • 要解决的问题:即使连续使用时重复显影,也可以提供展现良好的通电启动的调色剂,并能长时间地再现稳定的图像而不受温度或湿度的影响。 解决方案:电荷控制剂含有通式(1)表示的金属络盐化合物,当将1重量%的化合物分散在其中时,其电导率控制在110μS/ cm以下 离子交换水。 还提供了用于显影含有电荷控制剂的静电荷图像的调色剂。 在该式中,M表示配位中心金属如Fe; Ar表示取代或未取代的芳基; X和Y表示-O-等; 并且K + 表示钠离子等,或者可以是它们的混合物; m表示1,2,3或6; p表示金属M的化合价; n表示1,2或4; q表示0或整数。 版权所有(C)2012,JPO&INPIT

    • PROBLEM TO BE SOLVED: To provide organic solvent soluble dyes, in particular, to provide organic solvent soluble metal complex dyes containing chelated metal atoms.
      SOLUTION: The invention provides organic solvent soluble nonionic copper or nickel complex azo dyes having ranges widened in solubility and compatibility to solvents. The dyes have a widened range of solvent solubility from aliphatic hydrocarbons to a lower alcohol depending on individual chemical structures. The dyes are compatible with many organic solvents in various ratios, the dyes, for example, are hard to crystallize or form solid precipitation even in incorporated into such as ink. The solvents can be replaced partly or whole with a dispersant, surfactant or other appropriate substance, and configured as able to convert the dyes into a stable aqueous dispersion.
