摘要： Improved green-sensitivity is imparted to a photosensitive silver halide emulsion by a benzimidazolothiacarbocyanine dye of the formula: ##SPC1##Wherein R.sup.1 and R.sup.2 are lower alkyl; R.sup.3 is sulfoalkyl or carboxyalkyl each having an alkylene chain of from 1 to 4 carbon atoms inclusive; R.sup.4 is hydrogen, halogen, lower alkyl, lower carbalkoxy, lower alkoxy or acetamido; R.sup.5 is halogen, cyano or carbalkoxy; R.sup.6 is hydrogen or halogen; Y is an anion customary in the cyanine dye art; and n is 0 or 1.

摘要： Photosensitive silver halide emulsions for use in diffusion transfer processes are stabilized without adversely affecting spectral sensitization by the following steps: (a) spectrally sensitizing the silver halide grains; (b) lowering the pH of the emulsion from a first pH of the emulsion subsequent to chemical ripening to a pH of about 5.5 to 4.0 and/or increasing the Br ion/Ag ratio to at least 5 mg Br ion/gAg and, subsequent to steps (a) and (b), (c) adding 5-80 mg/gAg to said emulsion of a stabilizer selected from the group consisting of an hydroxy triazaindene, an amino triazaindene, an hydroxy tetrazaindene, an amino tetrazaindene, an hydroxy pentazaindene and an amino pentazaindene.
