Abstract: The invention relates to a layered construction with a protective layer and a photoexposed photopolymer layer, the protective layer being obtainable by reaction of a mixture comprising or consisting of at least one radiation-curing resin I), a polyfunctional radiation-curing resin II) and a photoinitiator system III), the radiation-curing resin I) comprising ≦5 wt. % of compounds having a weight-average molecular weight 1000, the polyfunctional radiation-curing resin II) comprising or consisting of at least one acrylate having at least two radiation-curing groups, and the mixture comprising at least 55 wt. % of the radiation-curing resin I) and not more than 35 wt. % of the polyfunctional radiation-curing resin II). The invention further relates to a method for producing a layered construction of this kind, and also to its use.
