ABSTRACT:
An imaging material in which images are formed by exposing a sheet having on a surface a layer of microcapsules containing a radiation sensitive internal phase, and rupturing the microcapsules; wherein images in the form of transparent windows are formed in an opaque image-receiving layer containing a light-scattering pigment by rendering the pigment transparent with the internal phase released from the ruptured microcapsules.
