Claim Text:
1. A laminate comprising an exposed photopolymer film and a layer of adhesive joined at least regionally to the photopolymer film, the photopolymer film comprising crosslinked polyurethane matrix polymers A), crosslinked writing monomers B) and a monomeric fluorourethane additive C), wherein the layer of adhesive is designed as a diffusion barrier for the fluorourethane additive C), wherein on an ATR-IR measurement there is no time-dependent change in the absorption spectrum and at no point in time an intensity difference of more than 3% in an absorption peak in a difference spectrum, if the layer of adhesive is wetted with the fluorourethane additive C), wherein the layer of adhesive comprises a urethane-based adhesive of high network density, which is obtained by reacting components that have number-average equivalent molar masses of <1500 g/mol.
