Abstract

A silver halide color photographic light-sensitive material improved in graininess, comprising a support having thereon a red-sensitive silver halide emulsion layer, a green-sensitive silver halide emulsion layer and a blue-sensitive silver halide emulsion layer, wherein at least one of the red-sensitive emulsion layer and the green-sensitive emulsion layer has the three-layered structure, in which the low speed silver halide emulsion layer, medium speed silver halide emulsion layer and high speed silver halide emulsion layer are coated on the support in this order; and the coating amount of silver in the layer increases in the order of the medium speed layer, low speed layer and high speed layer.

Claims

exact text as granted — not AI-modified
What is claimed is: 
     
       1. A silver halide color photographic light-sensitive material comprising a support having thereon a red-sensitive silver halide emulsion layer, a green-sensitive silver halide emulsion layer and a blue-sensitive silver halide emulsion layer, wherein said green-sensitive emulsion layer has a three-layered structure, in which a low speed silver halide emulsion layer, medium speed silver halide emulsion layer and high speed silver halide emulsion layer are coated on said support in this order; and the coating amount of silver in the layers increases in the order of the medium speed layer, low speed layer and high speed layer. 
     
     
       2. The photographic material of claim 1, wherein the red-sensitive silver halide emulsion layer and the green-sensitive siler halide emulsion layer each have the layer structure in which the low speed layer, medium speed layer and high speed layer are coated on a support in this order. 
     
     
       3. The photographic material of claim 2, wherein the blue-sensitive silver halide emulsion layer has the layer structure in which the low speed layer, medium speed layer and high speed layer are coated on a support in this order. 
     
     
       4. The photographic material of claim 1, wherein the total coating amount of silver in the photographic material is 2.0 to 10.0 g/m 2 . 
     
     
       5. The photographic material of claim 4, wherein the total amount of silver is 4.0 to 8.0 g/m 2 .
