titleOfInvention | Photographic bleach composition and process |
abstract | An aqueous photographic bleach solution comprises, as primary oxidant,nin a concentration eg from about 0.1 to about 1 Molar of a transition metalnoxidizing agent and, as secondary oxidant, from about 0.03 to about 0.15 Molarnof a persulphate or from about 0.1 to about 0.8 Molar of a peroxide. The primarynoxidant is preferably a ferric complex of an aminopolycarboxylic acid such asnethylene diamine tetraacetic acid (EDTA), propylene diamine tetraacetic acidn(PDTA), diethylene triamine pentaacetic acid (DTPA), or a substituted iminondiacetic acid such as methyl imino diacetic acid (MIDA). n The peroxide can be provided by a compound that liberates peroxide undernthe bleach conditions. n The solutions of the invention are particularly suitable for use with a singlenuse surface application device in which a small volume of the solution is usednonce and then discarded. |
