    摘要： A process for producing images on a photosensitive material comprising a support and a normally positive-working photosensitive layer is disclosed. The photosensitive layer is activated by exposure to ultraviolet light and imaging is effected by means of thermal energy. A mixture comprising a compound containing at least one --C--O--C-- or --C--O--Si-- bond which can be split by acid and a compound forming a strong acid upon exposure is employed in the photosensitive layer and imaging in the activated region is carried out by means of laser or electron beams or with the aid of a thermal printer. The process of the invention is suitable for use with digital techniques and makes it possible, in a simple manner, to employ a combined procedure for imaging the photosensitive material (photocomposing).

    摘要： A light-sensitive mixture containing a light-sensitive compound or a light-sensitive combination of compounds, the solubility of which is increased upon exposure, and a binder made from a polymer which has units of alkenylsulfonylaminocarbonyloxystyrenes or cycloalkenylsulfonylaminocarbonyloxystyrenes and which is insoluble in water and soluble in aqueous alkali. Moreover, a recording material is described which is particularly used in the production of printing plates coated with a light-sensitive layer of the indicated mixture. The printing form obtained after exposure and development of the material can be baked at temperatures ranging from 180.degree. C. to 250.degree. C. without forming difficult to remove deposits on the non-image areas of the plate. As a result, a printing form is produced, which has a particularly high resistance and yields a large print run.
