ABSTRACT:
An imaging system in which images are formed by image-wise exposing a layer containing a chromogenic material and a photosensitive composition in which at least the photosensitive composition is encapsulated in a layer of pressure rupturable capsules. Exposure and capsule rupture renders the chromogenic material image-wise accessible to the developer for a patterned image forming reaction.
