<p>An information recording element which information is recordable by means of light, in particular laser light. The recording element comprises a substrate provided on one side with a radiation-cured layer, in particular a U.V. light-cured layer of a radiation-curable solvent-free liquid composition having at least one ethene group per molecule. Each radiation-cured layer is provided with a servo track on its surface remote from the substrate and an ablative information recording layer capable, by exposure to laser-type radiation, of forming an optically readable information track, situated on the surface of the radiation-cured layer in contact with the servo track.</p> |
