The use of oxythioamido substituted arylhydrazides in producing images in silver halide photographic elements is disclosed. The oxythioamido substituted arylhydrazide can be incorporated in photographic silver halide emulsions. The oxythioamido substituent is capable of promoting adsorption of the arylhydrazide to silver halide grain surfaces. In negative working surface latent image forming emulsions the oxythioamido substituted arylhydrazides permit higher speeds to be achieved. In direct positive internal latent image forming emulsions increased nucleation activity can be achieved.
本发明公开了在卤化银感光元件中使用氧硫代氨基取代的芳基肼来产生图像的方法。 氧硫代氨基取代的芳基肼可以加入到卤化银感光乳剂中。 氧硫代氨基取代基能够促进芳基肼在卤化银颗粒表面的吸附。 在负工作表面潜像形成乳剂中,氧硫代氨基取代的芳基肼可以实现更高的速度。 在直接正内部潜像形成乳剂中,可以实现更高的成核活性。
