Diffusion transfer material |
abstract |
A photographic silver halide material comprising a compound which is capable of being reduced by a silver halide developing agent at a rate slower than that of image-wise developable silver halide and in reduced state is capable of releasing a photographically useful group, characterized in that said compound corresponds to the following formula :n wherein :n R 10 and R 20 (same or different)n (1) represent an alkyl group, a cycloalkyl group, an alkenyl group, a cycloalkenyl group or an aralkyl group including said groups in substituted form, (2) represent an aryl group including a substituted aryl group, or (3) represent a heterocyclic ring residue including such residue in substituted form or R'° and R 20 are ringclosed, either R'° or R 20 containing a ballasting group conferring diffusion resistance to the com- pond in hydrophilic colloid media when penetrated by an aqueous alkaline liquid; L' and L 2 (same or different) represent an NHCO-:n group; p and q (same or different) represent an integer 0 or 1; Z represents an atom or an atom group which is electronegative with respect to carbon, and PUG represents together with Z a releasable photographically useful group. |
