Abstract
The present invention provides a photosensitive material having a support, a layer containing opacifying agent, a layer containing microcapsules and a layer of developer material. The layer containing opacifying agent, the layer containing microcapsules and the layer of developer material are positioned such that upon rupturing the microcapsules, the color former diffuses to the developer material layer to form an image in the developer material layer. The final image is viewed against the opacifying agent.
Claims12
A photosensitive material comprising:
- a support,
- a layer containing opacifying agent,
- a layer containing microcapsules wherein said microcapsules contain a color former and a photohardenable or photosoftenable photosensitive composition, and
- a layer of developer material;
- wherein said layer containing opacifying agent, said layer containing microcapsules, and said layer of developer material are positioned such that upon rupturing said microcapsules, said color former diffuses to said developer material layer to form an image in said developer material layer and said image is viewed against said layer containing opacifying agent and said layer containing opacifying agent shields said microcapsules from said image.
2 more elements
An imaging process comprising:
- exposing a photosensitive material to actinic radiation wherein said photosensitive material comprises a support, a layer containing opacifying agent, and a layer containing microcapsules wherein said microcapsules contain a color former and a photohardenable or photosoftenable photosensitive composition and a layer of developer material;
- and
- rupturing said microcapsules such that said color former diffuses to said developer material layer to form an image in said developer material layer and said image is viewed against said opacifying agent.
