摘要:
A photographic light-sensitive material comprising a support having provided thereon at least one light-sensitive silver halide emulsion layer in combination with an immobile LDA compound represented by the following general formula (I): ##STR1## wherein n, x, y and z each stands for an integer of 1 or 2; m stands for an integer of 1 or more; D stands for a group containing an electron donor or its precursor moiety; A stands for an organic group linking Nup to --E--Q--Col or D; Nup stands for a precursor of a nucleophilic group; E stands for an electrophilic center; Q is a divalent group; Col stands for a group containing a dye or its precursor moiety; Ball stands for a ballast group; L stands for a linking group; and M stands for an optional substituent, said LDA compound being capable of releasing a diffusible dye or its precursor upon redox reaction.
