    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.

    Abstract translation: 公开了一种感光材料，其具有形成在诸如铝板的支撑体上的第一感光层，其上的剥离层和形成在剥离层上的第二感光层，使得第二层可以 照相曝光和照相显影独立于第一感光层，第一感光层可随后用作为照相掩模的第二感光层上形成的图像照相曝光。 在照相显影第一感光层之后，两个感光层可以用于不同的目的，例如，使用第一感光层作为印版，第二感光层作为用于制造重复印版的照相胶片。 由于第一感光层可以用不受控制的光照相曝光，而第二感光层可以用强度较小的激光束照相曝光，所以该感光材料对于在扫描图像处理装置上使用是非常有用的。 此外，还公开了方便地利用感光材料的方法。

    Abstract: A photosensitive lithographic printing plate precursor and a method for the preparation of a lithographic printing plate is described, said precursor comprising a support, a non-silver photosensitive layer and a photographic silver halide emulsion coating, and exhibiting photographic camera speed and a printing durability equivalent to the conventional type presensitized plate due to the underlying non-silver photosensitive layer; the silver halide emulsion coating contains a compound represented by the formual (I)R.sup.1 NHNHCOR.sup.2 (I)in which R.sup.1 represents an aryl group and R.sup.2 represents hydrogen, an aryl group, or an aliphatic group.

    Abstract: AN ELEMENT COMPRISING A LIGHT-HARDENABLE LAYER UPON WHICH IS COATED A PHOTODEVELOPABLE COLLOID SILVER HALIDE EMULSION. THE PHOTODEVELOPABLE SILVER HALIDE EMULSION IS EXPOSED, PHOTODEVELOPED, AND THE IMAGE USED AS A NEGATIVE TO EXPOSE THE UNDERLYING COMPOSITION WHICH IS TREATED TO REMOVE THE COMPOSITION IS UNEXPOSED, BUT NOT IN EXPOSED AREA. PRINTING RELIEFS SUITABLE FOR LETTERPRESS AND OFFSET PRINTING AND PRINTED CIRCUITS CAN BE MADE FROM THE ELEMENTS OF THE INVENTION, USING WASH-OFF PROCEDURES OR THERMAL TRANSFER MEANS WHEREBY UNHARDENED IMAGE AREAS ADHERE TO A PREVIOUSLY OR SUBSEQUENTLY APPLIED RECEPTOR SHEET OR PLATE.
