| titleOfInvention | Competing color developer composition |
| abstract | 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. |
