ABSTRACT:
An improved means for exposing and developing photosensitive sheets employing a microencapsulated radiation sensitive composition wherein a cover sheet is adhered to a layer of the microcapsules and following exposure the cover sheet is peeled away to rupture the microcapsules and develop the image. The cover sheet also reduces the oxygen concentration at the surface of the microcapsules and thereby enhances the sensitivity of the imaging sheet.
