Abstract

A silver halide photographic photosensitive material, containing at least one residual-color-reducing agent having at least one aromatic ring or aromatic heterocycle in its molecule; a processing method thereof; and an image-forming method.

Claims (10)

1. A silver halide photographic photosensitive material adapted for imagewise exposure followed by development processing, said photosensitive material prior to processing with a processing solution comprising at least one compound represented by the following formula (I):

A 1 -(X 1 )n 1 -B 1 -(X 2 )n 2 -A 2 Mdmd  Formula (I)

wherein, in formula (I), A 1 and A 2 each are a naphthyl group having at least one carboxy group; B 1 represents an atomic group having a π electron; X 1 and X 2 each represent a linking group; n 1 and n 2 each represent 0 or 1; Md represents a counter ion for balancing a charge; and md represents a number of 0 or more required for neutralizing a charge on the molecule.

2. A silver halide photographic photosensitive material adapted for imagewise exposure followed by development processing, said photosensitive material prior to processing with a processing solution comprising at least one compound represented by the following formula (IV):

A 1 -X 1 -L-X 2 -A 2   Formula (IV)

wherein, in formula (IV), A 1 and A 2 each are a substituted or unsubstituted naphthyl group; L represents a divalent group derived from compounds having a π electron; and X 1 and X 2 each represent a divalent linking group.

3. A silver halide photographic photosensitive material adapted for imagewise exposure followed by development processing, said photosensitive material prior to processing with a processing solution comprising at least one compound represented by the following formula (I):

A 1 -(X 1 )n 1 -B 1 -(X 2 )n 2 -A 2 Mdmd  Formula (I)

wherein, in formula (I), A 1 and A 2 each are a substituted or unsubstituted naphthyl group; B 1 represents an atomic group having a π electron; X 1 and X 2 each represent a linking group; n 1 and n 2 each represent 0 or 1; Md represents a counter ion for balancing a charge; and md represents a number of 0 or more required for neutralizing a charge on the molecule; and

wherein the at least one silver halide emulsion incorporated in the silver halide photographic photosensitive material contains dye chromophores being multilayer-adsorbed on the surface of silver halide grains.
