Claim 6

The silver halide color photographic material of claim 1, wherein the diameter of the tabular silver halide grains is 0.6 to 5.0 μm.

Claim 7

The silver halide color photographic material of claim 1, wherein the thickness of the tabular silver halide grains is 0.05 to 0.5 μm.

Claim 8

The silver halide color photographic material of claim 1, wherein the red-sensitive emulsion layer and/or the green-sensitive emulsion layer contains said dye in an amount sufficient to reduce the sensitivity thereof by 30% or more.

Claim 9
