Abstract
A silver halide photographic lightsensitive material comprising a support having thereon at least one lightsensitive silver halide emulsion layer, wherein the lightsensitive material contains at least one compound represented by general formula (I) and at least one photographically useful group-releasing compound represented by general formula (II) or (III) that is capable of forming a compound having substantially no contribution to a dye after its coupling with an oxidized form of a developing agent: (X)k-(L)m-(A-B)n (I) COUP1-D1 (II) COUP2-C-E-D2 (III) The definitions of the substituents are set forth in the specification.
Claims11
A silver halide photographic lightsensitive material comprising a support having thereon at least one red-sensitive layer, at least one green-sensitive layer and at least one blue-sensitive layer wherein the at least one blue-sensitive layer contains at least one compound represented by formula (I), and an emulsified dispersion containing at least one surfactant having a critical micelle concentration of 4.0×10−3 mol/L or less in an amount of 0.01% by weight or more based on all the ingredients contained in the blue-sensitive layer:
- (X)k−(L)m−(A-B)n (I)
- wherein X represents an adsorbing group to silver halide or a light-absorbing group having at least one atom selected from the group consisting of N, S, P, Se and Te;
- L represents a bivalent linking group having at least one atom selected from the group consisting of C, N, S and O;
- A represents an electron-donating group;
- B represents a leaving group or a hydrogen atom, wherein after—(A-B)n portion is oxidized, B is eliminated or deprotonated thereby to form a radical A.;
- k and m independently represent an integer of 0 to 3;
- and n represents 1 or 2.
