1. A method of recording information, wherein the information to be recorded is introduced as crosslinking pattern into a polymer layer by position-resolved (local) irradiation of a layer of a radiation-crosslinkable polymer composition, the crosslinking pattern being thereby produced, and wherein the information contained in the crosslinking pattern can be read out as a result of a local change in infrared absorption, Raman reflectance, fluorescence, luminescence and/or in the refractive index generated in the polymer composition by the crosslinking;wherein the radiation crosslinkable polymer composition is on a support; and wherein following the exposure of the coating a UV absorbing layer is applied. 2. The method of claim 1, wherein the polymer composition comprises a radiation activatable compound (photo initiator) which causes crosslinking upon irradiation.3. The method as claimed in claim 1, wherein the polymer composition comprises a radiation activatable compound which is selected from acetophenone, benzophenone, a derivative of acetophenone or of benzophenone, which can also be copolymer-attached.4. The method as claimed in claim 1, wherein the polymer composition comprises a fluorescence chromophore, which can also be incorporated by copolymerization.5. The method as claimed in claim 1, wherein the polymer composition comprises a fluorescence chromophore which is selected from the group consisting of coumarin, (bis)stilbene, perylene, phenanthridine, fluorene, a derivative of coumarin, (bis)stilbene, perylene, phenanthridine, fluorene, and combinations thereof.6. The method as claimed in claim 1, wherein the support is selected from the group consisting of labels, adhesive tapes, films (smart labels), coated, and metallic surfaces (smart coatings).7. A method of recording and retrieving information, wherein the information is recorded by the method as claimed in claim 1, and wherein the information is retrieved by reading out the information contained in the crosslinking pattern through the analysis of the local changes of the refractive index, the infrared absorption spectrum, the Raman reflectance spectrum, the fluorescence or the luminescence in the polymer layer.8. A method of recording and retrieving information, wherein the information is recorded by the method as claimed in claim 1, and wherein the information is retrieved by reading out the information contained in the crosslinking pattern through the analysis of the local changes of the refractive index, the infrared absorption spectrum, the Raman reflectance spectrum, the fluorescence or the luminescence in the polymer layer.9. A method of recording information, wherein the information to be recorded is introduced as crosslinking pattern into a polymer layer by position-resolved (local) irradiation of a layer of a radiation-crosslinkable polymer composition, the crosslinking pattern being thereby produced, and wherein the information contained in the crosslinking pattern can be read out as a result of a local change in infrared absorption, Raman reflectance, fluorescence, luminescence and/or in the refractive index generated in the polymer composition by the crosslinking;wherein the information is a digitalized information. 10. The method of claim 9, wherein the polymer composition comprises a radiation activatable compound (photo initiator) which causes crosslinking upon irradiation.11. The method as claimed in claim 10, wherein the polymer composition comprises a radiation activatable compound which is selected from acetophenone, benzophenone, a derivative of acetophenone or of benzophenone, which can also be copolymer-attached.12.

The method as claimed in claim 9, wherein the radiation crosslinkable polymer composition is on a support; wherein the support is selected from the group consisting of labels, adhesive tapes, films (smart labels), coated, and metallic surfaces (smart coatings).17. A method of recording and retrieving information, wherein the information is recorded by the method as claimed in claim 9, and wherein the information is retrieved by reading out the information contained in the crosslinking pattern through the analysis of the local changes of the refractive index, the infrared absorption spectrum, the Raman reflectance spectrum, the fluorescence or the luminescence in the polymer layer.18. A method of recording information, wherein the information to be recorded is introduced as crosslinking pattern into a polymer layer by position-resolved (local) irradiation of a layer of a radiation-crosslinkable polymer composition, the crosslinking pattern being thereby produced, and wherein the information contained in the crosslinking pattern can be read out as a result of a local change in infrared absorption, Raman reflectance, fluorescence, luminescence and/or in the refractive index generated in the polymer composition by the crosslinking;wherein the information to be recorded is introduced as a crosslinking pattern in the form of dot codes or bar codes into the polymer layer. 19.
