Silver halide photographic materials

Claim 1

A silver halide color photographic material having one layer of silver halide emulsion layers containing a silver halide having a silver chloride content of not less than 25 molar % and a color coupler, characterized in that at least one of said silver halide emulsion layers contains a silver halide sensitized with a compound having at least one of the following formula (Ia), and the following formula (Ib) and is hardened with a compound having at least one of the following formula (II) and a compound having the formula (III); ##STR18## wherein each of R 1 and R 2 represents an alkyl group; each of Z 1 and Z 2 represents a nonmetallic atom group for forming a 5- or 6-membered nitrogen-containing heterocyclic ring; X represents an anion; each of n 1 and n 2 is 1 or 2; and m is 1 or 2 provided that, when an inner salt is formed, m is 1; ##STR19## wherein each of R 13 , R 16 , R 17 and R 20 represents a hydrogen atom, a hydroxy group, a group of --OR of a group of ##STR20## in which R is an alkyl or aryl group and each of R' and R" is a hydrogen atom or an alkyl or aryl group having at least one of a sulfonic acid group or a carboxylic acid group; and each of R 14 , R 15 , R 18 and R 19 represents a hydrogen atom, a sulfonic acid group, a carboxylic acid group or an alkyl or aryl group having at least one of a sulfonic acid group or a carboxylic acid group; ##STR21## wherein R 9 represents a chlorine atom, a hydroxyl group, an alkyl group, an alkoxy group, a group of ##STR22## in which each of R 91 and R 92 is a hydrogen atom, an alkyl group or an aryl group, a group of 13 NHCOR 93 , in which R 93 is a hydrogen atom, an alkyl group, an aryl group or an alkylthio group, or a group of --OH, in which M is a monovalent metal atom; and R 10 is the same as R 9 except for a chlorine atom; ##STR23## wherein each of R 11 and R 12 represents a chlorine atom, a hydroxyl group, an alkyl group, an alkoxy group or a group of --OM, in which M is as defined above; each of Q and Q' represents a binding group of --O--, --S-- or --NH--; L represents an alkylene group of an arylene group; and each of p and q is 0 or 1.
