Abstract
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.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
86 words
A method to recover resources incorporated in a photographic material which comprises: processing an exposed silver salt light-sensitive photographic material by color development processing including a dye image-forming process but not removal of light-sensitive compositions and photographically processed material to form an image; reading the obtained image information by optical reading means; obtaining digital image information by converting the optically read information to electrical signals; recording the digital image information on a recording medium; and recovering resources comprising silver and film base from processed photographic material.
Claim 2
Independent Claim
86 words
A method to recover resources incorporated in a photographic material which comprises: processing an exposed silver salt light-sensitive photographic material by color development processing including a dye image-forming process but not removal of light-sensitive compositions and photographically processed material to form an image; reading the obtained image information by optical reading means; obtaining digital image information by converting the optically read information to electrical signals; recording the digital image information on a recording medium; and recovering resources comprising silver and film base from processed photographic material.
Claim 3
Dependent Claim
19 words
The method of claim 1 wherein the silver salt light-sensitive photographic material is a silver halide light-sensitive photographic material.
Claim 4
Dependent Claim
15 words
The method of claim 1 wherein the color development process is a thermal photographic process.
Claim 5
Dependent Claim
20 words
The method of claim 1 wherein the step of recovering resources includes recovering silver-comprising resources from the processed photographic material.
Claim 6
Dependent Claim
34 words
The method of claim 1 wherein the step of recovering resources from processed photographic material includes a step of transportating silver-comprising resources to a silver-recovering facility without changing a configuration of image-capturing photographic materials.
Claim 7
Dependent Claim
32 words
The method of claim 1 wherein the step of recovering resources from processed photographic material includes a step of recovering silver from processed photographic materials and recycling supports of the photographic materials.
Claim 8
Dependent Claim
17 words
The method according to claim 1, wherein said recovering resources consist essentially of silver and film base.
Claim 9
Independent Claim
72 words
A method to recover resources incorporated in a photographic material, which comprises: processing an exposed silver halide light-sensitive photographic material by color development processing, without processing bleaching or fixing; reading the obtained image information by optical reading means; obtaining digital image information by converting the optically read information to electrical signals, recording the digital image information on a recording medium, and recovering resources comprising silver and film base from processed photographic material.
Claim 10
Independent Claim
72 words
A method to recover resources incorporated in a photographic material, which comprises: processing an exposed silver halide light-sensitive photographic material by color development processing, without processing bleaching or fixing; reading the obtained image information by optical reading means; obtaining digital image information by converting the optically read information to electrical signals, recording the digital image information on a recording medium, and recovering resources comprising silver and film base from processed photographic material.
