    摘要： An optical storage medium having a layered structure suitable for use in security application, such as, e.g. smart cards or smart labels is disclosed. The medium comprises (a) a photoaddressable layer that includes a polymer the molecular structure of which includes at least one structural unit conforming to formula (I) and (b) substrate layer. Embodiments of the medium that further include at least one member selected from the group consisting of a transparent barrier layer, reflection layer and an adhesive layer, interposed between the photoaddressable layer and the substrate layer are also disclosed.

    摘要： An article of manufacture containing a substrate and a coating, e.g. optical date storage medium is disclosed. The coating characterised in that real component n and imaginary component k of its refractive index are at least 1.70 and not more than 0.016, respectively, its surface roughness, as the Ra value, is less than 20 nm and a scratch resistance of less than or equal to 0.75 μm scratch depth. Also disclosed is a process for the production of the coated article.
