Abstract
Abstract A silver halide color photographic material is disclosed. The material is comprised of a support base having provided thereon a fine grain silver halide emulsion layer and, positioned adjacent to the fine grain silver halide emulsion layer, a silver halide emulsion layer containing a coupler. The coupler is a phenolic cyan coupler substituted at the 5-position with an acylamino group and at the 2-position with an ureido group. The material has high sensitivity and good granularity. The material produces an image which has excellent fastness to light and heat.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
60 words
A silver halide color photographic material comprising: a support having coated thereon; at least one layer of silver halide emulsion containing a phenolic cyan coupler which is substituted by an acylamino group at the 5-position and by an ureido group at the 2-position; and at least one layer, adjacent to said coupler-containing layer, containing a fine grain silver halide emulsion.
Claim 2
Dependent Claim
60 words
A silver halide color photographic material comprising: a support having coated thereon; at least one layer of silver halide emulsion containing a phenolic cyan coupler which is substituted by an acylamino group at the 5-position and by an ureido group at the 2-position; and at least one layer, adjacent to said coupler-containing layer, containing a fine grain silver halide emulsion.
Claim 3
Dependent Claim
122 words
A silver halide color photographic material as claimed in claim 1, wherein the phenolic cyan coupler is a coupler represented by the general formula (I): ##STR4## wherein R is an alkyl group, an aryl group or a heterocyclic group, which may be substituted, R 1 is a group selected from the group consisting of a hydrogen atom, a halogen atom, a sulfonyl group, a sulfonamide group, a sulfamoyl group, a polyfluoroalkyl group, an acyl group, an alkoxycarbonyl group, an acylamino group and a cyano group, n is an integer of 1 to 5, R 1 may be the same or different when n is 2 or more, and X is a group which can be eliminated at oxidative-coupling with a developing agent.
Claim 4
Dependent Claim
26 words
A silver halide color photographic material as claimed in claim 2, wherein R is a cyclic or alicyclic alkyl group containing 1 to 22 carbon atoms.
Claim 5
Dependent Claim
61 words
A silver halide color photographic materials as claimed in claim 2, wherein R 1 is a halogen atom, a sulfonyl group, a sulfonamido group, a sulfamoyl group, a polyfluoroalkyl group, an acyl group, an alkoxycarbonyl group or an acylamino group, n is 1 or 2, and the substituents are located at the m- or p-position with respect to the ureido group.
Claim 6
Dependent Claim
29 words
A silver halide color photographic material as claimed in claim 2, wherein R 1 is a sulfonyl group, a sulfonamido group, or a sulfamoyl group and n is 1.
Claim 7
Dependent Claim
45 words
A silver halide color photographic material as claimed in claim 2, wherein X is a hydrogen atom, a halogen atom, an alkoxy group, an aryloxy group, an acyloxy group, a sulfonyloxy group, an amido group, an alkoxycarbonyloxy group, an aryloxycarbonyloxy group or an imido group.
