ABSTRACT:
A silver halide color photographic material is disclosed comprising at least one silver halide emulsion layer on a support, wherein at least one type of development inhibitor releasing type coupler is present which, by means of a coupling reaction with the oxidized form of a primary aromatic amine developing agent, releases a precursor of a compound, the precursor inhibiting the development of silver halide which subsequently, by means of an electron transfer reaction via an ethylenic conjugated chain, releases a compound which inhibits the development of silver halide, and at least one type of bleach accelerating agent releasing type coupler is present which, by means of a coupling reaction with the oxidized form of primary aromatic amine developing agent, releases a bleach accelerating agent or a precursor thereof.
