ABSTRACT:
A transfer imaging system is disclosed wherein images are formed by image-wise exposing a layer comprising a chromogenic material and pressure rupturable capsules containing, as an internal phase, a photosensitive composition. In a preferred embodiment, the chromogenic material is encapsulated with the photosensitive composition. Upon exposure and capsule rupture the chromogenic material is image-wise transferrable to a developer or copy sheet where the chromogenic material reacts with a developer to form an image. Preferred systems are sensitive to U.V. or blue light in the wavelength range of 380 to 480 nm.
