摘要:
Disclosed is a silver halide photographic lightsensitive material which comprises a support and at least one hydrophilic colloid layer including a silver halide emulsion layer, said hydrophilic colloid layer layer containing at least one dye represented by the following formula (I): ##STR1## (where R.sub.1 represents an alkyl group, R.sub.2 represents an alkyl group or an aryl group, Y represents a group of atoms necessary to form a saturated hydrocarbon ring or a saturated heterocyclic ring together with the carbon atom on the 3 position of pyrrole ring having Z, Z represents a group of atoms necessary to form a benzo condensed ring or a naphtho condensed ring, n represents 1 or 2, m represent 1 or 2 and m is 1 when the dye forms an inner salt, and X.crclbar. represents an anion, with a proviso that a molecule of the dye has at least one acid substituent.
