Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
79 words
A COLOR PHOTOGRAPHIC MATERIAL COMPRISING A SUPPORT HAVING THEREON AT LEAST ONE BLUE-SENSITIVE SILVER HALIDE EMULSION LAYER CONTAINING A YELLOW DYE-FORMING COUPLER, AT LEAST ONE RED-SENSITIVE EMULSION LAYER CONTAINING A CYAN DYEFORMING COUPLER, AT LEAST ONE GREEN-SENSITIVE EMULSION LAYER CONTAINING A MAGNETA DYE-FORMING COUPLER, AND AT LEAST ONE SILVER HALIDE EMULSION LAYER CONTAINING A BLEACH INHIBITOR HAVING AT LEAST TWO OXYETHYLENE GROUPS, SAID SILVER HALIDE EMULSION LAYER SUBSTANTIALLY NOT BEING CAPABLE OF FORMING A DYE IMAGE FOR PICTURE RECORDING.
Claim 2
Dependent Claim
79 words
A COLOR PHOTOGRAPHIC MATERIAL COMPRISING A SUPPORT HAVING THEREON AT LEAST ONE BLUE-SENSITIVE SILVER HALIDE EMULSION LAYER CONTAINING A YELLOW DYE-FORMING COUPLER, AT LEAST ONE RED-SENSITIVE EMULSION LAYER CONTAINING A CYAN DYEFORMING COUPLER, AT LEAST ONE GREEN-SENSITIVE EMULSION LAYER CONTAINING A MAGNETA DYE-FORMING COUPLER, AND AT LEAST ONE SILVER HALIDE EMULSION LAYER CONTAINING A BLEACH INHIBITOR HAVING AT LEAST TWO OXYETHYLENE GROUPS, SAID SILVER HALIDE EMULSION LAYER SUBSTANTIALLY NOT BEING CAPABLE OF FORMING A DYE IMAGE FOR PICTURE RECORDING.
Claim 3
Dependent Claim
28 words
The color photographic material as set forth in claim 1 wherein said silver halide emulsion layer containing the bleach inhibitor is formed adjacent to the green-sensitive emulsion layer.
Claim 4
Dependent Claim
33 words
The color photographic material as set forth in claim 1 wherein said silver halide emulsion layer containing the bleach inhibitor is formed adjacent to an intermediate layer adjacent to the green-sensitive emulsion layer.
Claim 5
Dependent Claim
28 words
The color photographic material as set forth in claim 1 wherein said silver halide emulsion layer containing the bleach inhibitor is formed adjacent to the blue-sensitive emulsion layer.
Claim 6
Dependent Claim
28 words
The color photographic material as set forth in claim 1 wherein said silver halide emulsion layer is formed adjacent an intermediate layer adjacent to the blue-sensitive emulsion layer.
Claim 7
Dependent Claim
24 words
The color photographic material as set forth in claim 1 wherein said silver halide emulsion layer containing the bleach inhibitor further contains a coupler.
Claim 8
Dependent Claim
39 words
The color photographic material as set forth in claim 1 wherein said silver halide emulsion layer containing the bleach inhibitor has a sensitivity lower than one-fourth of the sensitivity of the silver halide emulsion layers for forming dye images.
Claim 9
Dependent Claim
21 words
The color photographic material as set forth in claim 1 wherein said color photographic material is a color photographic print film.
Claim 10
Dependent Claim
33 words
A process of forming dye images and silver images in the color photographic material as set forth in claim 1 comprising subjecting said color photographic material to exposure, color development, bleaching and fixing.
Claim 11
Dependent Claim
20 words
The process as set forth in claim 9 wherein said bleach and said fix are conducted in a mono-bath system.
