Silver halide emulsion containing a purified cysteine-glutaraldehyde
polymer fraction and process of making
摘要:
From the complex reaction mixture of cysteine and glutaraldehyde a low molecular weight polymer is recovered for use as an additive to silver halide emulsions and developers to increase speed. Iron and nickel complexes of the purified low molecular weight polymer are similarly useful for silver halide emulsions.
