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 contacting the imaging sheets with a traveling pile formed by magnetically attractable free particles on a magnetic brush to rupture the microcapsules coating the surfaces of the imaging sheets by means of a soft pliable brushing action of the pile against the imaging sheets.
