41 words
A color reversal photographic light-sensitive material having at least one light-sensitive silver halide emulsion layer, wherein at least one of said emulsion layer and a layer adjacent thereto contains a silver halide emulsion of silver halide grains containing internal fog centers.
Claim 2
Dependent Claim
41 words
A color reversal photographic light-sensitive material having at least one light-sensitive silver halide emulsion layer, wherein at least one of said emulsion layer and a layer adjacent thereto contains a silver halide emulsion of silver halide grains containing internal fog centers.
Claim 3
Dependent Claim
51 words
A color reversal photographic light-sensitive material as in Claim 1, wherein said silver halide emulsion of silver halide grains containing internal fog centers is an emulsion comprising core-shell type silver halide grains having a structure such that the surface-fogged silver halide inner core is covered with a silver halide outer shell.
Claim 4
Dependent Claim

A color reversal photographic light-sensitive material as in Claim 2, wherein the thickness of the outer shell is selected between 50 and 1,000 A.
Claim 5
Dependent Claim
42 words
A color reversal photographic light-sensitive material as in Claim 1, wherein from 0.0005 to 0.50 mol of the silver halide emulsion of silver halide grains containing internal fog centers is used per mol of light-sensitive silver halide emulsions used in combination thereof.
Claim 6
Dependent Claim
42 words
A color reversal photographic light-sensitive material as in Claim 1, wherein from 0.001 to 0.25 mol of the silver halide emulsion of silver halidc grains containing internal fog centers is used per mol of light-sensitive silver halide emulsions used in combination thereof.
Claim 7
Dependent Claim
42 words
A color reversal photographic light-sensitive material as in Claim 1, wherein from 0.005 to 0.10 mol of the silver halide emulsion of silver halide grains containing internal fog centers is used per mol of light-sensitive silver halide emulsions used in combination thereof.
Claim 8
Dependent Claim
131 words
A color reversal photographic light-sensitive material as in Claim 1, wherein said silver halide emulsion of silver halide grains containing internal fog centers is an emulsion capable of providing (1) almost no increase in density when subjected to 2- minute processing (normal processing),and (2) when subjected to 10-minute processing (push processing), an increase in density as high as at least five times that obtained by the 2-minute processing is obtained, in which the 2-minute processing and the 10-minute processing are carried out by coating the emulsion on a film support in a silver amount coated of 0.5 g/m 2 , processing the resulting sample without exposure at 38°C for 2 minutes (normal processing) and at 38°C for 10 minutes (push processing) using a developer of the following formulation, Formulation of Developer:
Claim 11
Dependent Claim
57 words
A color reversal photographic light-sensitive material as in Claim 1, wherein said light-sensitive silver halide emulsion layer is formed as two or more separate layers having the same color sensitivity and unequel speed and said silver halide emulsion of silver halide grains containing internal fog centers is added to a lower speed layer of the separate layers.
Claim 12
Dependent Claim
93 words
A color reversal photographic light-sensitive material as in Claim. 1, wherein the material comprises a support coated thereon with at least one lower speed red-sensitive emulsion layer, at least one higher speed red-sensitive emulsion layer, at least one lower speed green-sensitive emulsion layer, at least one higher speed green-sensitive emulsion layer, at least one lower speed blue-sensitive emulsion layer and at least one higher speed blue-sensitive emulsion layer, and said silver halide emulsion of silver halide grains containing internal fog centers is added to at least one layer of the lower speed layers.
Claim 13
Dependent Claim
59 words
A process for forming a positive color image comprising exposing, black-and-white developing (first development), reversing and color developing a color reversal photographic light-sensitive material having at least one light-sensitive silver halide emulsion layer, wherein at least one of said emulsion layer and a layer adjacent thereto contains a silver halide emulsion of silver halide grains containing internal fog centers.
Claim 14
Dependent Claim
59 words
A process for forming a positive color image comprising exposing, black-and-white developing (first development), reversing and color developing a color reversal photographic light-sensitive material having at least one light-sensitive silver halide emulsion layer, wherein at least one of said emulsion layer and a layer adjacent thereto contains a silver halide emulsion of silver halide grains containing internal fog centers.
Claim 15
Dependent Claim
21 words
A process for forming a positive color image as in Claim 10, wherein said first development is pushed Lo increase speed.
