Claims
- 1. A silver halide light-sensitive photographic material comprising a light-sensitive silver halide emulsion layer provided on a support, wherein the light-sensitive silver halide emulsion layer comprises a sensitizing dye represented by the general formula I: ##STR21## wherein, W.sub.1 is a fluorine-substituted alkyl group; W.sub.2, W.sub.3 and W.sub.4 independently are a group selected from a group consisting of a fluorine free aliphatic group, an aromatic group, a halogen atom, an acylamino group carbamoyl group, a carboxyl group, a sulfonamide group and a sulfamoyl group;
- n.sub.1 is 1 or 2;
- n.sub.2, n.sub.3 and n.sub.4 are independently 0, 1 or 2;
- R.sub.1 and R.sub.2 are an aliphatic group or an aromatic group which may be substituted, provided that they may be either same or different;
- X is an oxygen atom or an alkyl-substituted nitrogen atom;
- L is a hydrogen atom or an alkyl group;
- A is a counter ion which is necessary to neutralize ion charge of the molecule; and
- n.sub.5 represents zero or one.
- 2. The silver halide light-sensitive photographic material of claim 1, wherein X is an oxygen atom.
- 3. The silver halide light-sensitive photographic material of claim 1, wherein W.sub.1 is --CHF.sub.2, --CF.sub.3, --CF.sub.2 CHF.sub.2, --C.sub.3 HF.sub.6 or --C.sub.3 F.sub.7.
- 4. The silver halide light-sensitive photographic material of claim 3, wherein W.sub.1 is a tri-fluoromethyl group.
- 5. The silver halide light-sensitive photographic material of claim 1, wherein R.sub.1 and R.sub.2 are an aliphatic group or an aromatic group having at least one sulfo group as a substituent.
- 6. The silver halide light-sensitive photographic material of claim 5, wherein R.sub.1 and R.sub.2 sulfoethyl group, sulfopropyl group, 3-sulfobutyl group, 4-sulfobutyl group, a or 2-hydroxy-3-sulfopropyl group.
- 7. The silver halide light-sensitive photographic material of claim 1, wherein X is an oxygen atom.
- 8. The silver halide light-sensitive photographic material of claim 1, wherein L is an ethyl group.
- 9. The silver halide light-sensitive photographic material of claim 1 wherein said sensitizing dye contains a maximum of one fluorine-substituted aliphatic group.
