Abstract
Image reproduction process utilizing an imagewise exposed photosensitive element comprising a solvent-processable photosensitive layer and a nonphotosensitive elastomeric tonable contiguous layer. Color proofs can be made by the process.
Claims15
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.
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,
- 3. 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.
