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. Transition metal complexes of the purified low molecular weight polymer are similarly useful for silver halide emulsions.
