发明名称 Dye mordanting development
摘要 A gelatino-silver halide film is exposed and then developed with a tanning developer bearing a positively or negatively charged substituent, e.g., a quaternary amine-substituted hydroquinone, to produce a charged matrix in the gelatin. To enhance the image the film is then processed to mordant an oppositely charged species, e.g., an anionic dye, to the charged matrix.
