<p>ENHANCED BLEACHING OF PHOTOGRAPHIC ELEMENTS CONTAINING SILVER HALIDE AND ADSORBED DYE The bleaching from photographic elements of silver produced by the development of silver halide having a dye adsorbed to its surface by employing as a bleaching agent a ferric complex of a polycarboxylic acid is improved by the presence of a compound of the formula: (I) wherein Ar is an aromatic linking group, R1, R2, R3, and R4 are hydroxy substituted lower alkyl groups, R5 and R6 are lower alkanediyl groups, X is a charge balancing counter ion, x and y are 0 or 1, and z is 0, 1, or 2.</p> |
