Abstract
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.
