ABSTRACT:
Imaging sheets having a coating containing chromogenic material and a photosensitive composition, with at least the photosensitive composition encapsulated in rupturable microcapsules as an internal phase, are processed by free particle abrasion to rupture the microcapsules coating the surfaces of the imaging sheets by establishing relative motion between the imaging sheets and a body of free particles.
