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