ABSTRACT:
Silver halide emulsions can be spectrally sensitized by adding a silver salt solution to them until the pAg value reaches a point close to equivalence, then adjusting the pAg value to a value between 7.5 and 10 by addition of halide or thiocyanate, adsorbing a part quantity of a sensitizing dye on the silver halide crystals of the emulsions, and repeating these steps once to seven times, and adding the residual quantity of sensitizing dye in the last repeat.
