Claim:
1. An assembly comprising a substrate and a photopolymer film, which are joined to one another partably at least in sections, the substrate comprising polyethylene terephthalate, and the photopolymer film comprising three-dimensionally crosslinked polyurethane matrix polymers, a writing monomer and a photoinitiator, wherein the substrate, after seven-day incubation at 23° C. in a 0.5 volume percent butyl acetate solution of the dye of formula (I) has an L value L1 and before the incubation an L value of L0, the L values being determined by CieLAB measurements, and the difference between the L values L1 and L0 satisfying the formula (II) and wherein the substrate has a surface tension of ≧28 mN/m and ≦42.5 mN/m.
