Abstract
Disclosed is a photosensitive material which has a first photosensitive layer formed on a support body such as an aluminum plate, a peel-off layer thereon and a second photosensitive layer formed on the peel-off layer in such a manner that the second layer can be photographically exposed to light and photographically developed independently from the first photosensitive layer and the first photosensitive layer may be subsequently photographically exposed with the picture image formed on the second photosensitive layer acting as a photographic mask. After the first photosensitive layer has been photographically developed, the two photosensitive layers may be used for different purposes, for instance, using the first photosensitive layer as a printing plate and the second photosensitive layer as a photographic film for making duplicate printing plates. Since the first photosensitive layer may be photographically exposed with uncontrolled light while the second photosensitive layer may be photographically exposed with a laser beam of small intensity, this photosensitive material is highly useful for use on a scanning image processing device. Also, a method of conveniently utilizing the photosensitive material is additionally disclosed.
