Abstract

The present invention relates to the use of at least one radiation crosslinkable, preferably UV crosslinkable, polymer composition as a data recording medium, especially in the form of what are known as smart coatings based on such polymer compositions, which in a further embodiment comprises at least one fluorescence chromophore, and also to a composite at least comprising one support and one layer comprising a radiation crosslinkable polymer composition comprising at least one fluorescence chromophore, and also, preferably, an additional UV absorbing layer.
