摘要:
The addition of 3-substituted-5-mercapto-1H-tetrazoles to silver halide photothermographic emulsions improves the post-processing stability of the emulsion.
摘要:
The present invention relates to a light-sensitive silver halide photographic material comprising a support and silver halide emulsion layer or layers, wherein at least one of said silver halide emulsion layers comprises an alkylaminomercaptotetrazole antifoggant. According to a preferred embodiment of the present invention said silver halide emulsion layer comprises tabular silver halide grains having an average aspect ratio higher than 3:1 and a thickness lower than 0.4 .mu.m.
