Claim 2

A silver halide color photographic material comprising: a support; and a pluraity of photographic layers including silver halide emulsion layer formed thereon, wherein one of said photographic layers is comprised of a compound containing recurring unit represented by the formula (I) in an amount of at least 0.01 mole percent ##STR18## wherein R represents hydrogen, an alkyl group having 1 to 6 carbon atoms, or a halogen group; M represents hydrogen, an alkali metal, an alkaline earth metal, or an organic base; X represents an alkyl group having 1 to 6 carbon atoms, an alkoxy group, an alkylamino group or a halogen group; m represents 0, 1, or 2 and n represents 1 or 2.

Claim 3

A silver halide color photographic material as claimed in claim 1 wherein the compound having the recurring unit is incorporated in one of the silver halide emulsion layers of the color photographic material.

Claim 4

The silver halide color photographic material as claimed in claim 2 wherein the compound is incorporated in a silver halide emulsion layer further comprising a yellow coupler.

Claim 5

The silver halide color photographic material as claimed in claim 1, 2 or 3 wherein the compound is incorporated in a silver halide emulsion layer further comprising a yellow coupler of the formula (III): ##STR19## wherein R 1 represents an aryl group which may be substituted by an aryl group having 1-10 carbon atoms, an acylamino group, or an alkoxy group having 1-5 carbon atoms; a tertiary alkyl group; an anilino which may be substituted by R 2 , R 3 , R 4 and R 5 ; wherein R 2 is hydrogen, a halogen group, or an alkoxy group having 1-3 carbon atoms; and wherein R 3 , R 4 and R 5 are each independently hydrogen, an alkoxy group having 1-2 carbon atoms, an alkoxycarbonyl group having 10-20 carbon atoms, and acylamino group, a sulfonamino group, a sulfamoyl group, or a carbamoly group; wherein X represents hydrogen, ##STR20## wherein R 6 and R represents hydrogen, a halogen group, a carboxylic acid ester group, an amino group, an alkyl group, an alkylthio group, an alkoxy group, an alkylsulfoxy group, a carboxlic acid group, a sulfonic acid group, an unsubstituted or substituted phenyl group, or a heterocyclic group; wherein R 8 and R 9 represent hydrogen, a halogen group, a alkyl group having 1-20 carbon atoms, a phenyl group, a benzyl group, an alkoxy group, an alkoxycarbonyl group, or a carboxy group; wherein R 10 represents a substituted or unsubstituted aryl group or a heterocyclic group; and wherein Z represents a non-metallic atomic group necessary for forming a 4-membered, 5-membered or 6-membered ring together with ##STR21## of X; and having a pK value of lower than 8.0.

Claim 6

The silver halide color photographic material as claimed in claim 1 wherein the compound contains at least 1 mole percent of the recurring unit.

Claim 7

The silver halide color photographic material as claimed in claim 1 wherein the compound having the recurring unit has a molecular weight of 1,000 to 2,000,000.

Claim 8

The silver halide color photographic material as claimed in claim 1 wherein the compound having the recurring unit has a molecular weight of 10,000 to 500,000.

Claim 9

The silver halide color photographic material as claimed in claim 1 where in the amount of the compound having the recurring unit incorporated in the photographic layer is 0.05 to 20 g per square meter of the color photographic material.

Claim 10

The silver halide color photographic material as claimed in claim 3 wherein the amount of the compound having the recurring unit is 5 to 100 g per mole of the yellow coupler.
