Zusammenfassung:	Fluorescent read-only media multilayered information carrier with separated fluorescent information carrier regions (511) against non-fluorescent background (512) in each layer (509) and the methods for making this. A photolithography process where the data carriers are formed from an originally non-fluorescent photosensitive layer (509) applied directly onto the photomask (501), followed by exposing the layer (509) through the photomask to produce fluorescent information pits (511) immediately in front of the transparent regions (504) of the photomask. Special photochemically stable transparent luminophors which control the spectral and luminescent properties of the data carrier layers (509) are generated in the photosensitive compositions. L'invention concerne des supports d'information multicouches fluorescents en lecture seule comportant des zones de support d'information fluorescentes séparées (511) sur un arrière-plan non fluorescent (512) dans chaque couche (509), ainsi que les procédés pour la fabrication de ces supports. On utilise un procédé photolithographique dans lequel les supports de données sont formés à partir d'une couche photosensible non fluorescente à l'origine (509) appliquée directement sur le photomasque, la couche (509) étant ensuite exposée à travers le photomasque afin de produire des dépressions d'information fluorescentes (511) juste en face des zones transparentes (504) du photomasque. Des luminophores spéciaux transparents, stables photochimiquement et commandant les propriétés spectrales et luminescentes des couches de support de données (509) sont générés dans les compositions photosensibles.
