Abstract

A high-sensitivity silver halide photographic light-sensitive material is provided, which is a silver halide photographic light-sensitive material, in which a dye chromophore is adsorbed in multiple layers on the surface of a silver halide grain and at least one of the dye chromophore-containing compounds satisfies: a specific condition relating to the aggregation property, hydrophilicity/hydrophobicity or J-aggregation property; or a specific structure.

Claims (27)

1. A silver halide photographic light-sensitive material comprising a silver halide photographic emulsion containing a silver halide grain, wherein the silver halide photographic emulsion includes a dye compound consisting of one chromophore adsorbed in multiple layers on the surface of the silver halide grain, and the chromophore of the dye compound is Dye X satisfying Condition 1 represented by the following formula (1):

{Agg(Dye X )/Agg(Dye 1)}≧1.1

wherein Agg(Dye 1) represents an aggregation property of the following Dye 1 and Agg(Dye X) represents an aggregation property of Dye X:

2. A silver halide photographic light-sensitive material comprising a silver halide photographic emulsion containing a silver halide grain, wherein the silver halide photographic emulsion includes a dye compound consisting of one chromophore adsorbed in multiple layers on the surface of the silver halide grain, and the chromophore of the dye compound is Dye X satisfying Condition 2 represented by the following formula (2):

{log P (Dye X )/log P (Dye 1)}≧1.1

wherein log P(Dye 1) represents a hydrophilicity/hydrophobicity of the following Dye 1 and log P(Dye X) represents a hydrophilicity/hydrophobicity of Dye X:

3. A silver halide photographic light-sensitive material comprising a silver halide photographic emulsion containing a silver halide grain, wherein the silver halide photographic emulsion includes a dye compound consisting of one chromophore adsorbed in multiple layers on the surface of the silver halide grain, and the chromophore of the dye compound is Dye X satisfying Condition 3 represented by the following formula (3);

{ J -Agg(Dye X )/ J -Agg(Dye 1)}≧1.1

wherein J-Agg(Dye 1) represents a J-aggregation property of the following Dye 1 and J-Agg(Dye X) represents a J-aggregation property of Dye X:

4. A silver halide photographic light-sensitive material comprising a silver halide photographic emulsion containing a silver halide grain, wherein the silver halide photographic emulsion includes a dye compound consisting of one chromophore adsorbed in multiple layers on the surface of the silver halide grain, and the chromophore of the dye compound is Dye X satisfying all of Conditions 1 to 3 represented by the following formulas (1) to (3), respectively:

Condition 1:

{Agg(Dye X )/Agg(Dye 1)}≧1.1  Formula (1)

wherein Agg(Dye 1) represents an aggregation property of the following Dye 1 and Agg(Dye X) represents an aggregation property of Dye X,

Condition 2:

{log P (Dye X )/log P (Dye 1)}≧1.1  Formula (2)

wherein log P(Dye 1) represents a hydrophilicity/hydrophobicity of the following Dye 1 and LogP(Dye X) represents a hydrophilicity/hydrophobicity of Dye X,

Condition 3:

{ J -Agg(Dye X ) J -Agg(Dye 1)}≧1.1  Formula (3)

wherein J-Agg(Dye 1) represents a J-aggregation property of the following Dye 1 and J-Agg(Dye X) represents a J-aggregation property of Dye X:

5. The silver halide photographic light-sensitive material as described in claim 1 , wherein in the silver halide photographic emulsion, tabular silver halide grains having an aspect ratio of 2 or more occupy 50% (area) or more of all silver halide grains in the emulsion.

6. The silver halide photographic light-sensitive material as described in claim 2 , wherein in the silver halide photographic emulsion, tabular silver halide grains having an aspect ratio of 2 or more occupy 50% (area) or more of all silver halide grains in the emulsion.

7. The silver halide photographic light-sensitive material as described in claim 3 , wherein in the silver halide photographic emulsion, tabular silver halide grains having an aspect ratio of 2 or more occupy 50% (area) or more of all silver halide grains in the emulsion.

8. The silver halide photographic light-sensitive material as described in claim 4 , wherein in the silver halide photographic emulsion, tabular silver halide grains having an aspect ratio of 2 or more occupy 50% (area) or more of all silver halide grains in the emulsion.

9. The silver halide photographic light-sensitive material as described in claim 1 , wherein the silver halide photographic emulsion is subjected to a selenium sensitization.

10. The silver halide photographic light-sensitive material as described in claim 2 , wherein the silver halide photographic emulsion is subjected to a selenium sensitization.

11. The silver halide photographic light-sensitive material as described in claim 3 , wherein the silver halide photographic emulsion is subjected to a selenium sensitization.
