Abstract
1442470 Bleaching photographic materials FUJI PHOTO FILM CO Ltd 5 July 1974 [7 July 1973] 30025/74 Heading G2C A developed, imagewise exposed silver halide photographic material is bleached with a bleaching solution containing (a) as the bleaching agent a complex formed from a polyvalent ferric iron, cobalt, nickel or cupric copper cation and an organic phosphonic acid and (b) a re-halogenating agent and treating the bleached material with a fixing solution. Suitably an amino-poly(methylene phosphonic acid, e.g. of the Formula R
