Beschreibung
Zusammenfassung:	Described is a light-sensitive mixture, the solubility of which in an aqueous-alkaline solution changes upon exposure to actinic radiation, containing at least one light-sensitive compound and a binder material comprising a halogenated polyvinyl phenol which is insoluble in water, but soluble in aqueousalkaline solutions. The mixture is preferably used for the Preparation of lithographic printing plates and leaves virtually no oleophilic remainders on the image-free areas of the support surface when the developed lithographic printing form is heated to temperatures above 200.degree.C.
