Silver halide photographic material.

摘要

A silver halide photographic material comprising a support having thereon at least one silver halide emulsion layer, wherein the layer contains at least one compound represented by the following formula (I) and at least one compound represented by the following formula (X): wherein R1, R2 and R3 are the same or different and each represents a substituted or unsubstituted aliphatic group, a substituted or unsubstituted aryl group or a substituted or unsubstituted heterocyclic group; R4 represents a hydrogen atom, a substituted or unsubstituted alkyl group, a substituted or unsubstituted aryl group or a substituted or unsubstituted heterocyclic group; and R1 and R2, and R3 and R4 each may be combined with each other to form a ring; wherein Z11 represents a sulfur atom, a selenium atom or a substituted nitrogen atom represented by in which R13 represents a substituted or unsubstituted alkyl group, a substituted or unsubstituted aryl group or a substituted or unsubstituted heterocyclic group; Z12 represents a sulfur atom, a selenium atom, an oxygen atom or a substituted nitrogen atom represented by in which R13a has the same meaning as R13; R11 and R12 are the same or different and each represents a substituted or unsubstituted alkyl group; V11, V12, V13, V14, V15, V16, V17 and V18 are the same or different and each represents a hydrogen atom or a monovalent substituent; and adjacent two substituents thereof may be combined with each other to form a ring; L11, L12 and L13 are the same or different and each represents a substituted or unsubstituted methine group; n11 represents 1, 2 or 3; M11 represents a counter ion for neutralizing charge; and m11 is a number of 0 or more necessary for neutralizing the molecular charge.
