Silver halide photographic material and methine dye

A silver halide photographic material which comprises a silver halide emulsion containing silver halide grains that are sensitized with at least one sensitizing methine dye represented by the following formula (I):

• wherein Y represents an atomic group necessary to form a 5- or 6-membered unsaturated heterocyclic ring, and Y may further be condensed with other 5- or 6-membered carbocyclic ring or heterocyclic ring, or may have a substituent;
• the bond between two carbon atoms in which Y is condensed may be a single bond or a double bond;
• Z represents an atomic group necessary to form a 5- or 6-membered nitrogen-containing heterocyclic ring, and Z may further be condensed with other 5- or 6-membered carbocyclic ring or heterocyclic ring;
• R represents a substituted or unsubstituted alkyl group, aryl group, or heterocyclic group;
• D represents a group necessary to form a sensitizing methine dye;
• L1 and L2 each represents a methine group;
• p represents 0 or 1;
• M represents a counter ion;
• and m represents a number of 0 or higher necessary to neutralize the charge in the molecule;
• wherein the condensed ring containing Y and Z in the sensitizing methine dye represented by formula (I) is selected from the following Y-1 to Y-26, provided that Y-1 to Y-3 and Y-6 to Y-26 may further be condensed with other 5- or 6-membered carbocylic or heterocyclic ring, or may have a substituent:
• in each structural formula, * represents a position to link to a methine chain.

A silver halide photographic material which comprises at least one methine dye represented by the following formula (XXXI) or (XXXII):

• V61 represents a halogen atom;
• X61 represents an oxygen atom, a sulfur atom, or a nitrogen atom;
• X62 represents an oxygen atom, a sulfur atom, a selenium atom, a nitrogen atom, or a carbon atom;
• Y62 represents an atomic group necessary to form a benzene ring or a 5- or 6-membered unsaturated heterocyclic ring, which may be condensed with other 5- or 6-membered carbocyclic or heterocyclic ring or may have a substituent, and two carbon atoms to which Y62 is condensed may be bonded by a single bond or a double bond;
• R61 and R62 each represents a substituted or unsubstituted alkyl group, a substituted or unsubstituted aryl group, or a substituted or unsubstituted heterocyclic group;
• n61 represents 0 or 1;
• M61 represents a counter ion;
• and m61 represents a number of 0 or higher necessary to neutralize the charge in the molecule.

• the bond between two carbon atoms in which Y is condensed may be a single bond or a double bond;
• Z represents an oxazole ring, a thiazole ring, an imidazole ring, a 2-pyridine ring or a 4-pyridine ring, and Z may further be condensed with other 5- or 6-membered carbocyclic ring or heterocyclic ring;
• R represents a substituted or unsubstituted alkyl group, aryl group, or heterocyclic group;
• D represents a group necessary to form a sensitizing methine dye;
• L1 and L2 each represents a methine group;
• p represents 0 or 1;
• M represents a counter ion;
• and m represents a number of 0 or higher necessary to neutralize the charge in the molecule.
