Abstract
Abstract A photographic light-sensitive material wherein at least one silver halide emulsion layer and/or photographic layer adjacent thereto contains a compound represented by the formula: R1 can be a one-five carbon atom alkyl group, a one-five carbon atom hydroxyalkyl group, a tetrafurfuryl group or a seven-12 carbon atom aralkyl group. R2 and R3 can be a hydrogen atom, a one-five carbon atom alkyl group or an atomic group capable of forming a ring via linkage with R2 and R3. Q can be a sulfur atom or an imino group. Further described is a method of photographic reproduction which comprises exposing a photographic light-sensitive material as described above and developing said exposed material with an infectious developer containing hydroquinone.
