PURPOSE:To obtain the titled developer having a good storage stability and less tendency for generating a color stain by incorporating diethyl hydroxyamine, etc., and poly(alkyleneimine) to a processing solution for the color processing of the photosensitive material. CONSTITUTION:The liquid color-developer contains at least one of the compd. selected from the group comprising diethyl hydroxyamine, dimethyl hydroxyamine and poly(alkyleneimine) shown by the formula where R1 is 1-6C alkylene group, R2 is alkyl group, (n) is an integer of 500-20,000. The poly(alkyleneimine) is exemplified by poly(ethyleneimine), poly(propyleneimine) and poly(N-methylethyleneimine), etc. Thus, by incorporating poly(alkyleneimine) together with diethylhydroxyamine or dimethylhydroxyamine to the liquid color- developer, the developer having the good storage stability and less tendency for generating the color stain is obtd. |
