Process for the production of protective coatings and relief structures Abstract: Coated material of a support, onto which is applied a radiation-sensitive coating of a homopolymer or copolymer with at least 5 mol %, based on the polymer, of structural units of the formula I Image (I) in which R is a divalent aliphatic radical which can be interrupted by hetero-atoms or aromatic, heterocyclic or cycloaliphatic groups, a cycloaliphatic, heterocyclic or araliphatic radical, an aromatic radical in which two aryl nuclei are linked via an aliphatic group, or an aromatic radical which is substituted by at least one alkyl, cyclo- alkyl, alkoxy, alkoxyalkyl, alkylthio, alkylthioalkyl, hydroxyalkyl, hydroxyalkoxy, hydroxyalkylthio or aralkyl group or in which two adjacent C atoms of the aromatic radi- cal are substituted by an alkylene group, R' independently has the same meaning as R and q is 0 or 1, and in which an aromatic radical R is not substituted by alkylene or by the abovementioned radicals if q is 0. The coating can be cross- linked directly by the effect of radiation. The material is suitable, for example, for the production of protective films and relief images.
