Claims
- 1. A silver halide light-sensitive photographic material comprising a support having thereon a blue-sensitive silver halide emulsion layer comprising a mixture of at least two kinds of silver halide emulsions each optically sensitized with at least one blue-sensitizing dye, wherein
- (1) said silver halide emulsions each comprise silver chloride grains or silver chlorobromide grains having a silver chloride content not less than 90 mol %,
- (2) said silver halide emulsions each have an average grain size, in terms of diameter of spherical grain, being within the range of 0.6 .mu.m to 0.9 .mu.m and being different from each other in the average grain size by 0.07 .mu.m to 0.15 .mu.m, and
- (3) a total coating amount of said at least one blue-sensitizing dye is not more than 7.0.times.10.sup.-4 g/m.sup.2.
- 2. The photographic material of claim 1, wherein said blue-sensitive emulsions are sensitized with a dye represented by the following Formula 1 and a dye represented by the following Formula 2: ##STR29## wherein Z.sub.1 and Z.sub.2 are independently a group of atoms necessary to complete a thiazole ring, a benzothiazole ring, a benzoselenazole ring, a naphthothiazole ring or a naphthoselenazole ring; R.sub.1 and R.sub.2 are independently an aliphatic group or an aliphatic group having a carboxyl group or a sulfo group provided that at least one of R.sub.1 and R.sub.2 is an aliphatic group having a carboxyl group or a sulfo group; X.sub.1 is an acid anion: and m is an integer of 0 or 1, ##STR30## wherein Z.sub.3 and Z.sub.4 are independently a group of atoms necessary to complete a thiazole ring, a benzothiazole ring or a benzoselenazole ring; R.sub.3 and R.sub.4 are independently an aliphatic group provided that at least one of R.sub.3 and R.sub.4 is an aliphatic group having a carboxyl group or a sulfo group; X.sub.2 is an acid anion: and n is an integer of 0 or 1.
- 3. The photographic material of claim 1, wherein the amount of said blue-sensitizing dye is 4.0.times.10.sup.-4 g/m.sup.2 to 7.0.times.10.sup.-4 g/m.sup.2.
- 4. The photographic material of claim 1, wherein said photographic material is a color photographic material further comprising a green-sensitizing silver halide emulsion layer and a red-sensitive silver halide emulsion layer.
