摘要： A color developer composition comprising a primary aromatic amino developing agent, a color-forming coupler, an alkali, and a water-soluble competing developing agent having the formula:
WHEREIN X and X'' each represents a p-hydroxyanilino group of which the benzene ring may further be substituted by a member selected from the class consisting of an alkyl group having from one to four carbon atoms, a hydroxyalkyl group having from one to four carbon atoms, an alkoxy group having from one to four carbon atoms and a halogen atom, and the X''-CH2-group may be located at the o-, m- or p-position to the position of the X-CH2-group. An improved color reversal development of a multilayer, multicolor photographic element is also claimed, where the improvement comprises utilizing, in at least one color developer used in the process, a water-soluble competing developing agent as above described. Further described is a composition for preparing a color developer solution comprising a primary aromatic amino developing agent and the water-soluble competing developing agent described above.-

摘要： Ferricyanide and/or ferrocyanide ions are effectively removed from waste photographic treating solutions by contacting the solutions with weakly basic anion exchange resins. Improved results are obtained with the free base form of the weakly basic anion exchange resin when contacting takes place in the presence of a compound having a buffering action at a pH of 7 to 9, e.g., in the presence of boric acid, metaboric acid or a water soluble borate. Upon regeneration of the anion exchange resin the eluted ions can be reused as a photographic processing solution, e.g., a bleaching solution, with the addition of make up components.
