ABSTRACT:
There is disclosed a silver halide photographic light-sensitive material containing a dye which colors a specific layer in the light-sensitive material and furthermore is quickly decolored and/or eluted during a development processing. The light-sensitive material contains at least one compound represented by the following formula (1), (2) or (3): ##STR1## wherein R.sup.11 represents a hydrogen atom, an alkyl group, an aryl group, --COOR.sup.16, or --CONR.sup.16 R.sup.17 ; R.sup.12, R.sup.13 and R.sup.14 each represents a hydrogen atom, an alkyl group, and an aryl group; R.sup.15 represents a hydrogen atom, an alkyl group, an aryl group, or an amino group; R.sup.13 and R.sup.14 may be combined to form a 6-membered ring; and R.sup.16 and R.sup.17 each represents a hydrogen atom, an alkyl group, and an aryl group; provided that the compound represented by formula (1) does not have a carboxy group or a salt thereof as a substituent; ##STR2## wherein R.sup.1 represents an alkyl group or an aryl group; R.sup.2 represents an alkyl group, an aryl group or a hydrogen atom; R.sup.3 represents a hydrogen atom or an alkyl group; R.sup.4, R.sup.5, R.sup.6 and R.sup.7 each represents a hydrogen atom, an alkyl group, an aryl group, a halogen atom, --OR.sup.21, --NR.sup.21 R.sup.22, --N(R.sup.21)SO.sub.2 R.sup.22, --N(R.sup.21)COR.sup.22, and --COOR.sup.21 ; and R.sup.21 and R.sup.22 each represents a hydrogen atom, an alkyl group and an aryl group; provided that the compound represented by formula (2) does not have a carboxy group or a salt thereof as a substituent; ##STR3## wherein R.sup.2, R.sup.3, R.sup.4, R.sup.5, R.sup.6 and R.sup.7 each represents the same groups as those defined for R.sup.2, R.sup.3, R.sup.4, R.sup.5, R.sup.6 and R.sup.7 in formula (2); X represents --SO.sub.2 NH--, --SO.sub.2 NHCO--, --CONHCO--, or --SO.sub.2 NHSO.sub.2 --; R.sup.8 represents an alkyl group, an aryl group or a heterocyclic group; R.sup.9 represents a hydrogen atom, an alkyl group, an aryl group, --OR.sup.23, --NR.sup.23 R.sup.24, --N(R.sup.23)COR.sup.24, or --COOR.sup.23 ; and R.sup.23 and R.sup.24 each represents a hydrogen atom, an alkyl group and an aryl group; provided that the compound represented by formula (3) does not have a carboxy group or a salt thereof as a substituent. There is also disclosed a methine dye represented by the above formula (1), (2) or (3).
