Abstract: 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.

Abstract: A developer composition of an alkaline aqueous solution containing a reducing inorganic salt, typically an alkali metal salt of sulfurous acid such as sodium sulfite, is found to be applicable for development of a lithographic printing plate material containing a photosensitive o-quinonediazide compound and an organic polymer, with reduced deterioration in developing capacity caused by the air and enhanced stability with lapse of time. In particular, a developer composition composed of an alkaline aqueous solution of pH 11 or higher containing a water-soluble sulfurous acid salt is effective for developing both of a lithographic printing plate material having a nega-type photosensitive layer containing a photosensitive diazo compound and an organic polymer, and a lithographic printing plate material having a posi-type photosensitive layer containing an o-quinonediazide compound and an organic polymer.

Abstract: In a dye image forming process in color photography comprising imagewise exposing a photographic element comprising a support and a light sensitive silver halide emulsion layer, and processing the exposed photographic element with an alkaline processing solution in the presence of a dye developer whereby a dye image corresponding to the imagewise exposure is formed by oxidation of said developer as a function of development of silver halide, the improvement which comprises the dye developer being a mono azo dye developer represented by the following formula:X--N.dbd.

Abstract: A novel color diffusion transfer photographic element is disclosed which is characterized as having a photosensitive element containing a compound represented by the formula ##STR1## wherein A represents oxygen or a group of the formula .dbd.NR (in which R represents hydroxyl or an amino group); X represents hydrogen or halogen; Z represents a group of nonmetallic atoms necessary to form a first ring and being a 5 to 7-membered nonaromatic hydrocarbon ring which may be fused with a second ring, at least one of said first ring and said second ring having one or more substituents wherein at least one of said substituents is a ballast group which renders said compound nondiffusible during processing with said solution; J represents a divalent group; D represents a dye moiety or a dye precursor moiety; and n represents zero or 1.

Abstract: An improved process for forming a dye image in an image receiving layer of a film unit containing a light-sensitive element and an image receiving element by incorporation therein of a compound represented by the formula ##STR1## WHEREIN R.sub.1 and R.sub.2 individually represent lower alkyl, and n is 3.

Abstract: A process for forming a dye image on a receiving element by diffusion transfer from a photosensitive element is disclosed wherein the exposed photosensitive element is processed with an alkaline solution in the presence of a particular dye developer having at least one azo radical.
