Silver halide photographic materials

A silver halide photographic material comprising a support having thereon at least one light-sensitive silver halide photographic emulsion layer and one hydrophilic colloid layer, which contains at least one nitrogen-containing heterocyclic ring compound having a charge represented by formula (I) in said emulsion layer or in a hydrophilic colloid layer adjacent thereto:

• ##STR11## wherein T, U, V and W each represents CH or N and the nitrogen-containing heterocyclic ring completed by T, U, V, and W contains 1 to 3 nitrogen atoms;
• R.sup.1 represents a substituent group;
• R.sup.2, R.sup.3, R.sup.4, R.sup.5 and R.sup.6 each represents a hydrogen atom or a substituent group, provided that at least one of R.sup.2 to R.sup.6 represents a group to be eliminated under an alkaline condition;
• X represents a counter ion for balancing charge;
• n represents the number of counter ions necessary for balancing said charge;
• and any pair of adjacent groups of R.sup.1 to R.sup.6 may combine with each other to form a ring.
