Abstract
A self-contained photosensitive material comprising: a support; an imaging layer on the support, the imaging layer comprising a developer material and a plurality of photosensitive microcapsules encapsulating a photosensitive composition and a color precursor; and a protective coating on the imaging layer, the protective coating comprising a cured film of a water-soluble or water-dispersible resin, wherein upon image-wise exposing the imaging layer to actinic radiation and rupturing the microcapsules, the color precursor is released from the microcapsules and reacts with the developer material to form a color image is disclosed.
Claims26
A self-contained photosensitive material comprising:
- a support;
- an imaging layer on the support, the imaging layer comprising a developer material and a plurality of photosensitive microcapsules encapsulating a photosensitive composition and a color precursor;
- and
- a protective coating on the imaging layer, the protective coating comprising a cured film of a water-soluble or water-dispersible resin and a crosslinking agent, wherein upon image-wise exposing the imaging layer to actinic radiation and rupturing the microcapsules, the color precursor is released from the microcapsules and reacts with the developer material to form a color image.
A photosensitive material comprising a support having a layer of microcapsules thereon, said photosensitive microcapsules including an internal phase containing a photosensitive composition and a color precursor wherein, upon image-wise exposing said photosensitive material to actinic radiation and rupturing said microcapsules in the presence of a developer material, said color precursor image-wise reacts with said developer to form a color image, the improvement wherein said photosensitive material further comprises a protective coating on said microcapsule layer, said protective coating comprising from about 50 to 90% of a water-soluble or water-dispersible resin and from about 2 to 20% of a crosslinking agent.
A method for producing a self-contained photosensitive material which comprises:
- (a) coating a photosensitive imaging composition on a support, said photosensitive imaging composition comprising a developer material and a plurality of photosensitive microcapsules encapsulating a photosensitive composition and a color precursor to form an imaging layer;
- (b) overcoating said imaging layer with a protective coating composition, said protective coating composition comprising a water-soluble or water-dispersible resin and a crosslinking agent;
- and
- (c) drying and/or curing said protective coating.
