    • A process for bleaching silver dye by using a black developer containing at least one thiazole derivative represented by the general formula (I): (wherein R represents a substituted or unsubstituted alkyl group, a substituted or unsubstituted aralkyl group, or a substituted or unsubstituted aryl group, and R' and R'' each represents a hydrogen atom or a substituted or unsubstituted alkyl group, or R' and R'', when taken together, form a benzene ring optionally substituted by an alkyl group) or at least one imidazole derivative represented by the general formula (II): (wherein R1, R2, R3, and R4 each represents a hydrogen atom, a substituted or unsubstituted alkyl group or an alkenyl group). Gradation of a finished image can be easily and surely flattened by using ordinary photo-sensitive materials and conducting ordinary processings. In addition, the black developer has an improved storage stability.
    • 通过使用含有至少一种由通式(I)表示的噻唑衍生物的黑色显影剂漂白银染料的方法:其中R表示取代或未取代的烷基,取代或未取代的芳烷基或取代的 或未取代的芳基,R'和R“各自表示氢原子或取代或未取代的烷基,或R'和R”,当一起形成任选被烷基取代的苯环时)或在 由通式(II)表示的至少一种咪唑衍生物:其中R1,R2,R3和R4各自表示氢原子,取代或未取代的烷基或烯基。 通过使用普通的感光材料和进行普通的处理,可以容易且可靠地平整成品图像的分级。 此外,黑色显影剂具有改善的储存稳定性。
