The photographic material comprises a support and provided thereon at least one silver halide emulsion layer containing at least one of the methine compounds represented by the following Formula (I) and at least one of the compounds represent-ed by the following Formula (II): ##STR1## wherein R.sup.1 represents --(CH.sub.2).sub.r --CONHSO.sub.2 --R.sup.3, --(CH.sub.2).sub.s --SO.sub.2 NHCO--R.sup.4, --(CH.sub.2).sub.t --CONHCO--R.sup.5, or --(CR.sub.2).sub.u --SO.sub.2 NHSO.sub.2 --R.sup.6, in which R.sup.3, R.sup.4, R.sup.5 and R.sup.6 each represent an alkyl group, an alkoxy group, or an amino group and r, s, t and u each repre-sent an integer of 1 to 5; R.sup.2 is synonymous with R.sup.1 or represents an alkyl group which is different from R.sup.1 ; Z.sup.1 and Z.sup.2 may be the same or different and represent the group of non-metallic atoms necessary to form a 5- or 6-membered heterocyclic ring; L.sub.1, L.sub.2 and L.sub.3 each represent a methine group; n.sub.1 represents 0, 1 or 2; X.sub.1 represents an anion; k.sub.1 represents a number necessary to adjust a charge in a molecule to 0; and p and q each represent 0 or 1. ##STR2## wherein R.sub.7 represents an aliphatic group or an aromatic group; R.sub.8 represents a hydrogen atom, an alkyl group, an aryl group, an alkoxy group, an aryloxy group, an amino group, or a hydrazino group; G.sub.1 represents a --CO-- group, a --SO.sub.2 -- group, a --SO-- group, a --P(O)R.sub.9 -- group, a --CO--CO-- group, a thiocarbonyl group, or an iminomethylene group; both of A.sub.1 and A.sub.2 represent a hydrogen atom, or either of them represents a hydrogen atom and another represents a substituted or unsubstituted alkylsulfonyl group, a substituted or unsubstituted arylsulfonyl group, or a substituted or unsubstituted acyl group; and R.sub.9 is selected from the same groups as those defined for R.sub.8 and may be different from R.sub.8.
