ABSTRACT:
A light-sensitive mixture, which is composed of a light-sensitive compound, for example, an o-quinone-diazide or a diazonium salt polycondensate, or a light-sensitive combination of compounds, for example, a photolytic acid donor and an acetal compound or orthocarboxylic acid compound which can be cleaved by acid, and of a novolak having halogenated phenol units is described. The mixture is preferably used for the preparation of printing plates, in particular planographic printing plates, which have an improved resistance to aqueous-alkaline developer solutions, gasoline hydrocarbons and fountain solutions containing alcohol.
