A silver halide color photographic material comprising a support having thereon at least one silver halide emulsion layer, wherein the silver halide color photographic material contains an image forming compound represented by the following general formula (I):
(Dye-X)q-Y (I)
wherein Dye represents a cyan dye group represented by the general formula (II) described below or a precursor thereof; X represents a chemical bond or a linking group; Y represents a group having a property of releasing Dye in correspondence or counter-correspondence to development of a light-sensitive silver salt having a latent image distributed imagewise and making a difference in diffusibility between the dye thus-released and the compound represented by (Dye-X)q-Y; Dye and X are connected with each other by C or E in the general formula (II); and q represents an integer of 1 or 2, and when q is 2, the two groups (Dye-X) may be the same or different:
wherein A represents a halogen atom, -OR¹ or -SR¹ (wherein R¹ represents an alkyl group, an aryl group or a heterocyclic group); B represents an electron withdrawing group having a Hammett's σp value of not less than 0.3; C represents a chemical bond, a hydrogen atom, an alkyl group, a cycloalkyl group, an aryl group, a halogen atom, -OR⁴, -CONR⁴R⁵, -SO₂NR⁴R⁵, -N(R³)-COR₄ or -N(R³) -SO₂R₄ (wherein R³, R⁴ and R⁵ each represents a hydrogen atom or a group selected from those defined for R¹, or R⁴ and R⁵ may combine with each other to form a 5-membered or 6-membered ring); E represents a chemical bond, a hydrogen atom, an alkyl group, a halogen atom, -OR⁴, -CONR⁴R⁵, -SO₂NR⁴R⁵, -N(R⁵)-COR⁴ or -N(R⁵)-SO₂R⁴ (wherein R⁴ and R⁵ have the same meaning as defined above); and G represents a hydroxy group or a salt thereof, or a group selected from those represented by the formula (T), (U) or (V):
wherein R²¹ and R²², which may be the same or different, each represents an alkyl group, a cycloalkyl group, an alkenyl group, an aralkyl group, an aryl group, a heterocyclic group, an alkylthio group, an arylthio group, an alkoxy group, an aryloxy group or an amino group, or R²¹ and R²² may combine with each other to form a 5-membered or 6-membered ring.
