Abstract
A method for providing a color image in an exposed color negative silver bromoiodide film element comprising contacting said element with an aqueous color developing composition having a pH of 9.0 to 12.0 and comprising a color developing agent, sulfite ion and an additional antioxidant wherein the color developing agent/sulfite ion molar ratio is less than 10:1 and greater than 0.55:1, and the sulfite ion/antioxidant molar ratio is less than 4.35:1 and greater than 0.25:1.
Claims18
A method for providing a color image in an exposed color negative silver bromoiodide film element comprising contacting said element with an aqueous color developing composition having a pH of 9.0 to 12.0 and comprising a color developing agent, sulfite ion and hydroxylamine sulfate wherein the color developing agent/sulfite ion molar ratio is less than 10:1 and greater than 0.55:1, and the sulfite ion/hydroxylamine sulfate molar ratio is less than 4.35:1 and greater than 0.25:1.
A method for providing a color image in an exposed color negative silver bromoiodide film element comprising contacting said element with an aqueous color developing composition having a pH of 9.0 to 12.0 and comprising a color developing agent in the amount of 0.027 to 0.068 mol/l, sulfite ion and hydroxylamine sulfate wherein the color developing agent/sulfite ion molar ratio is less than 10:1 and greater than 0.55:1, and the sulfite ion/hydroxylamine sulfate molar ratio is less than 4.35:1 and greater than 0.25:1.
