<p>A silver halide photosensitive material is described which comprises at least one layer of a silver halide emulsion layer provided on a base, wherein said at least one silver halide emulsion layer comprises at least one novel dye compound represented by general formula (I): <CHEM> wherein Z1 and Z2 each independently represents a sulfur atom or a selenium atom; R1 and R2 each independently represents an alkyl group, provided that at least one of R1 or R2 must represent a butyl group, a pentyl group, a hexyl group, a heptyl group or an octyl group; V1 V2, V3, V4, V5, V6, V7 and V8 each independently represents a hydrogen atom, a halogen atom, an alkyl group, an acyl group, an acyloxy group, an alkoxycarbonyl group, a carbamoyl group, a sulfamoyl group, a carboxy group, a cyano group, a hydroxy group, an amino group, an acylamino group, an alkoxy group, an alkylthio group, an alkylsulfonyl group, a sulfonate group, or an aryl group, provided that adjacent groups represented by V1 to V8 can bond to each other via their carbon atoms to form a condensed ring; X represents a charged ion in equilibrium, and n is a value necessary to neutralize the electrical charge of said dye compound.</p> |
