Claims Analysis
Total Claims: 19
Claim 1
Independent Claim
101 words
An image reproduction process comprising: (1) exposing imagewise to actinic radiation a photosensitive element comprised of, in order, (A) a solvent-processable photosensitive layer, (B) a nonphotasenitine tonable contiguous layer comprised of an elastomeric material, and (C) a sheet support, either the exposed or unexposed areas of said solvent-processable photosensitive layer being solvent-soluble after said imagewise exposure, (2) washing out either exposed or unexposed areas of said solvent-processable photosenstive layer while the other areas of said layer remain on said contiguous elastomeric layer, and (3) toning the areas of the contiguous elastomeric layer from which areas of the photosensitive layer were removed.
Claim 2
Dependent Claim
101 words
An image reproduction process comprising: (1) exposing imagewise to actinic radiation a photosensitive element comprised of, in order, (A) a solvent-processable photosensitive layer, (B) a nonphotasenitine tonable contiguous layer comprised of an elastomeric material, and (C) a sheet support, either the exposed or unexposed areas of said solvent-processable photosensitive layer being solvent-soluble after said imagewise exposure, (2) washing out either exposed or unexposed areas of said solvent-processable photosenstive layer while the other areas of said layer remain on said contiguous elastomeric layer, and (3) toning the areas of the contiguous elastomeric layer from which areas of the photosensitive layer were removed.
Claim 3
Dependent Claim
17 words
A process of claim 1 having a removable cover sheet or layer on said solvent-processable photosensitive layer.
Claim 4
Dependent Claim
25 words
A process of claim 1 wherein said solvent-processable photosensitive layer is comprised on an ethylenically unsaturated photohardenable material selected from photopolymerizable, photocrosslinkable, and photodimerizable compositions.
Claim 5
Dependent Claim
14 words
A process of claim 1 wherein said solvent-processable photosensitive layer is a photosoluble composition.
Claim 6
Dependent Claim
19 words
A process of claim 1 wherein said elastomeric layer has a glass transition temperature of -10° C. or lower.
Claim 7
Dependent Claim
15 words
A process of claim 5 wherein the elastometric layer is a butadiene polymer or copolymer.
Claim 8
Dependent Claim
27 words
A process of claim 1 wherein the unexposed areas of said solvent-processable photosensitive layer are washed out and the exposed areas remain on said contiguous elastomeric layer.
Claim 9
Dependent Claim
27 words
A process of claim 1 wherein the exposed areas of said solvent-processable photosensitive layer are washed out and the unexposed areas remain on said contiguous elastometric layer.
Claim 10
Dependent Claim
13 words
A process of claim 1 wherein said contiguous elastomeric layer contains a colorant.
Claim 11
Dependent Claim
12 words
A process of claim 1 wherein said solvent-processable photosensitive layer is colored.
Claim 12
Dependent Claim
15 words
A process of claim 1 wherein said contiguous elastomeric layer is toned with particulate material.
Claim 13
Dependent Claim
70 words
A process for producing an image from a photosensitive element comprising, in order from bottom to top, (A) a sheet support, (B) a tonable contiguous layer comprised of an elastomeric material, (C) a solvent-processable photosensitive layer, and (D) a removable cover sheet or layer, comprising: 1. removing said sheet support from said element, 2. laminating the surface of said contiguous layer of said element to a substrate, in either order,
Claim 14
Dependent Claim
70 words
A process for producing an image from a photosensitive element comprising, in order from bottom to top, (A) a sheet support, (B) a tonable contiguous layer comprised of an elastomeric material, (C) a solvent-processable photosensitive layer, and (D) a removable cover sheet or layer, comprising: 1. removing said sheet support from said element, 2. laminating the surface of said contiguous layer of said element to a substrate, in either order,
Claim 15
Dependent Claim
74 words
exposing said laminated photosensitive element imagewise to actinic radiation, either the exposed or unexposed areas of said solvent-processable photosensitive layer being solvent-soluble and 4. removing said cover sheet, then 5. washing out either exposed or unexposed areas of said solvent-processable photosensitive layer while the other areas of said layer remain on said contiguous elastomeric layer, and 6. toning the areas of the contiguous elastomeric layer from which areas of the photosensitive layer were removed.
Claim 16
Dependent Claim
74 words
exposing said laminated photosensitive element imagewise to actinic radiation, either the exposed or unexposed areas of said solvent-processable photosensitive layer being solvent-soluble and 4. removing said cover sheet, then 5. washing out either exposed or unexposed areas of said solvent-processable photosensitive layer while the other areas of said layer remain on said contiguous elastomeric layer, and 6. toning the areas of the contiguous elastomeric layer from which areas of the photosensitive layer were removed.
Claim 17
Dependent Claim
23 words
A process according to claim 12 wherein said element has a releasable layer interposed between said sheet support and said tonable contiguous layer.
Claim 18
Dependent Claim
47 words
A process according to claim 12 whereby a multilayer, image-bearing element is formed which comprises repeating said process steps (1) through (6) at least one, each succeeding element having its tonable layer in surface to surface contact with the image-bearing surface of the last previously laminated element.
Claim 19
Dependent Claim
21 words
A process according to claim 12 wherein the cover sheet is removed before imagewise exposing the laminated element to actinic radiation.
