Abstract

The present invention relates to a laminate structure comprising a protective layer and an exposed photopolymer layer, the laminate structure being obtainable by reacting at least one radiation-curing resin I), an isocyanate-functional resin II) and a photoinitiator system III), and the radiation-curing resin I) containing ≦5% by weight of compounds having a weight-average molecular weight of <500 and ≧75% by weight of compounds having a weight-average molecular weight of >1000, the isocyanate-functional resin II) containing ≦5% by weight of compounds having a weight-average molecular weight of <500, and the protective layer containing the radiation-curing resin I) at least to an extent of 80% by weight and the isocyanate-functional resin II) at most to an extent of 15% by weight. The invention further provides a process for producing the inventive laminate structure.
