## Abstract

A silver halide color photographic material comprising a support having thereon a cyan color-forming silver halide emulsion layer, a magenta color-forming silver halide emulsion layer, a yellow color-forming silver halide emulsion layer and at least one light-insensitive hydrophilic layer disposed farther from the support than any of these silver halide emulsion layers, in which the light-insensitive hydrophilic layer contains nonglobular fine-particle powder in a dispersion in an amount of at least 25% by weight based on the whole components therein, thereby ensuring excellent tone reproduction in the images and reduced dependence of image qualities upon the positions of viewing light sources. In addition, the color photographic material can provide images well-expressing a feeling of massiveness even in rapid photographic processing.

## Claims

### Claim 1

A silver halide color photographic material comprising a reflecting support having thereon a cyan color-forming silver halide emulsion layer, a magenta color-forming silver halide emulsion layer, a yellow color-forming silver halide emulsion layer and at least one light-insensitive hydrophilic layer disposed farther from the support than any of these silver halide emulsion layers, wherein said light-insensitive hydrophilic layer contains nonglobular fine-particle powder in a dispersion in an amount of at least 35% by weight based on the whole components therein.

### Claim 2 (depends on 1)

The silver halide color photographic material of claim 1, wherein the nonglobular fine-particle powder has an average particle size of from 0.6 to 5 .mu.m.

### Claim 3 (depends on 1)

The silver halide color photographic material of claim 1, wherein the amount of the nonglobular fine-particle powder is in the range of 50 to 95% by weight.

### Claim 4 (depends on 1)

The silver halide color photographic material of claim 1, wherein the nonglobular fine-particle powder comprises an inorganic substance.

### Claim 5 (depends on 4)

The silver halide color photographic material of claim 4, wherein the inorganic substance is an inorganic oxide, an alkaline earth metal salt or glass.

### Claim 6 (depends on 4)

The silver halide color photographic material of claim 4, wherein the inorganic substance is silica.

### Claim 7 (depends on 1)

The silver halide color photographic material of claim 1, wherein the reflecting support is a paper support having a waterproof resin coating filled with a white pigment in a density of at least 14% by weight on the emulsion layer-coated side.

### Claim 8 (depends on 1)

The silver halide color photographic material of claim 1, wherein the light-insensitive hydrophilic layer containing nonglobular fine-particle powder is the layer disposed farthest from the support on the emulsion layer-coated side.

### Claim 9 (depends on 1)

The silver halide color photographic material of claim 1, wherein the cyan color-forming silver halide emulsion layer, the magenta color-forming silver halide emulsion layer and the yellow color-forming silver halide emulsion layer each contains a high silver chloride emulsion having a silver chloride content of from 95 to 99.9 mole %.

### Claim 10 (depends on 9)

The silver halide color photographic material of claim 9, wherein at least one of the emulsions comprises silver chlorobromide grains having bromide-localized phases at the surface thereof.

### Claim 11 (depends on 5)

The silver halide color photographic material of claim 5, wherein said salt of an alkaline earth metal is a sulfate or carbonate salt.

### Claim 12 (depends on 11)

The silver halide color photographic material of claim 11, wherein said salt is selected from the group consisting of barium sulfate, calcium carbonate, and magnesium sulfate.

### Claim 13 (depends on 5)

The silver halide color photographic material claim 5, wherein the nonglobular fine-particle powder has an average particle size of from 0.6 to 5 .mu.m and is contained in an amount in the range of 50 to 95% by weight.
