A silver halide light-sensitive color photographic material is disclosed. A coupler represented by the formula is used.

Silver halide light-sensitive color photographic material

A method to recover the resources incorporated in a photographic material is disclosed. An exposed silver salt light-sensitive photographic material is subjected to color development processing; the obtained image information is optically read; digital image information is obtained by converting the read information to electrical signals, and the resulting image information is recorded on a recording medium, and resources incorporated in a photographic material is recovered from the processed photographic material.

Resources recovery method in a silver salt photographic system

A silver halide light-sensitive color photographic material comprising containing a coupler is disclosed. The coupler is represented by formula (VII): wherein PUG represents a photographically useful group; R represents a substituent; m represents an integer from 1 to 5; and n represents zero or an integer from 1 to 4, wherein the coupler has a group represented by formula (VII a) at a position other than active point of the coupler, ##STR1##

A method of manufacturing a sulfide comprises the steps of (a) dissolving a thiol in a solvent to form a solution; (b) oxidizing the thiol to a disulfide in the presence of a first oxidizing agent in the solution; (c) reacting the disulfide with a coupler in the presence of a base and a second oxidizing agent, without isolation of said disulfide from the solution, to form a reaction mixture in which the sulfide is produced; and (d) obtaining said sulfide.

Manufacturing method of sulfides

A silver halide color photographic light-sensitive material is disclosed. The light-sensitive material comprises a support, provided thereon, a blue-sensitive silver halide emulsion layer, a green-sensitive silver halide emulsion layer and a red-sensitive silver halide emulsion layer, and the green-sensitive emulsion layer contains a coupler represented by the following Formula I; ##STR1## wherein R.sub.1 is a hydrogen atom or a group capable of being released upon reaction with the oxidation product of a color developing agent; R.sub.2 is a chlorine atom or an alkoxyl group; R.sub.3 and R.sub.4 are each independently a hydrogen atom or a substituent, provided that when R.sub.3 is a hydrogen atom, R.sub.4 is a substituent; and R.sub.5, R.sub.6, R.sub.7, R.sub.8 and R.sub.9 are each a halogen atom.
