    • A silver halide photographic material having one or more silver halide emulsion layers formed on a reflective support is disclosed, wherein at least one of the silver halide emulsion layers contains at least one cyan coupler of formula (I) dispersed therein with the aid of at least one high-boiling organic solvent having a dielectric constant of 6.1 or more, and wherein at least one photographic layer contains at least one dye of formula (II) and/or formula (III): ##STR1## wherein R.sub.1 is a straight- or branched-chain alkyl group having 2 to 4 carbon atoms; R.sub.2 is a ballast group; and X is a hydrogen atom or a group capable of leaving upon coupling reaction with the oxidized product of a color developing agent; ##STR2## wherein R.sub.3 and R.sub.5 are each a hydrogen atom, an alkyl group or an aryl group; R.sub.4 and R.sub.6 are each an aryl group or a hetero ring having at least one sulfonic acid group or carboxyl group either directly or via an alkylene group having 1 to 4 carbon atoms; and n is an integer of 0, 1 or 2; ##STR3## wherein R.sub.7, R.sub.10, R.sub.11 and R.sub.14 are each a hydrogen atom, a hydroxyl group, --OR (wherein R is alkyl or aryl), ##STR4## (wherein R' and R" are each a hydrogen atom or an alkyl or aryl group having at least one sulfonic acid group or carboxyl group); R.sub.8, R.sub.9, R.sub.12 and R.sub.13 are each a hydrogen atom, a sulfonic acid group, a carboxyl group, or an alkyl or aryl group having at least one sulfonic acid group or carboxyl group.
