Claim 3

The photographic light-sensitive material of claim 1, wherein said alkyl group for R 1 is a straight chain, branched chain or cyclic alkyl group; said acyl group for R 1 is an alkylcarbonyl group or an alkylsulfonyl group in which the alkyl moiety thereof may be substituted with one or more of a halogen atom or a cyano group; said amino group for R 1 is an amino group, a monoalkylamino group, a dialkylamino group or an acylamino group; said sulfoalkyl group, the sulfoalkoxyalkyl group or the sulfoalkylthioalkyl group for Q may contain 1 or more of a halogen atom, a hydroxy group or an alkoxy group as a substituent in addition to the sulfo group substituent; said methine group for L is an unsubstituted methine group or a methine group substituted with an alkyl group; said alkyl group for R 5 , R 6 and R 7 is an unsubstituted alkyl group or an alkyl group substituted with one or more of a cyano group, a sulfo group, a carboxy group, a halogen atom, a hydroxy group, an alkoxycarbonyl group, an alkylcarbonyloxy group, an alkylsulfonyloxy group, an alkylcarbonyl group, an alkylsulfonyl group, an alkoxy group, and a alkylthio group; and said substituted alkyl group for R 6 and R 7 can be substituted further with one or more of an amino group, an alkylamino group, a dialkylamino group, an alkylcarbonylamino group and alkylsulfonylamino group and wherein said carboxy groups, said sulfo groups and said sulfo moieties of said sulfoalkyl groups, said sulfoalkoxyalkyl groups and said sulfoalkylthioalkyl groups may be a free carboxy or sulfo group or a salt of a carboxy or sulfo group.

Claim 4

The photographic light-sensitive material of claim 1, wherein R 1 is an alkyl group, a carboxy group, an alkoxycarbonyl group, an alkylcarbamoyl group, a hydroxy group, an alkoxy group, an acylamino group or an alkylureido group; Q is a sulfoalkyl group; L is an unsubstituted methine group; R 2 is a hydroxy group, an alkoxy group, a sulfoalkoxy group, an amino group, a dialkylamino group, an N-sulfoalkyl-N-alkylamino group, a di(sulfoalkyl)amino group or an N-(alkylsulfonylaminoalkyl)-N-alkylamino group; R 3 is a hydroxy group, a methoxy group or a methyl group; and R 4 is a hydrogen atom, a methyl group or a methoxy group.

Claim 5

The photographic light-sensitive material of claim 3, wherein R 2 is an alkoxy group, a sulfoalkoxy group, a dialkylamino group or an N-sulfoalkyl-N-alkylamino group.

Claim 6

Claim 7

The photographic light-sensitive material of claim 1, wherein said photographic light-sensitive material comprises a support having thereon at least one silver halide photographic emulsion layer.

Claim 8

The photographic light-sensitive material of claim 6, wherein said photographic light-sensitive material includes at least one non-light-sensitive hydrphilic colloid layer.

Claim 9

The photographic light-sensitive material of claim 6, wherein said dye having the formula (I) is present in said silver halide photographic emulsion layer.

Claim 10

The photographic light-sensitive material of claim 7, wherein said dye having the formula (I) is present in said silver halide photographic emulsion layer.

Claim 11
