Abstract
Abstract A silver halide light-sensitive photographic material comprises a support and a Lippmann emulsion layer on the support containing a silver halide and at least one compound of the following formula in a quantity of at least 3.5×10 -3 mole per mole of the silver halide of the Lippmann emulsion layer: ##STR1## wherein Z represents an atomic group necessary to form a heterocyclic ring; Y is a hydrogen atom or --S--R 1 group; R and R 1 are each a hydrogen atom, an alkali-metal atom, ammonium or an alkyl group; X and X 1 are each a divalent organic group; m and m 1 are each 0 or 1; and n is an integer of up to 3, provided if n is 0, Y is --S--R 1 group. The silver halide light-sensitive photographic material is developed in a developer containing at least 0.6 mole per liter of sulfurous ions.
