| titleOfInvention | Method for alleviating partial inactivation of color couplers |
| abstract | A method is disclosed for alleviating the partial inactivation of color couplers caused by adventitious reaction with vapors of formaldehyde or a vinyl monomer. Partial inactivation is evidenced by decreased spectral absorptivity of the dye produced by reaction of the color coupler with color dye-forming compounds, such as oxidized photographic color developing agents. The method comprises contacting a partially inactivated coupler with an aqueous solution comprising an oxidizing agent and an oxidation accelerator. |
