The present invention relates to a media for recording luminous signals in the visible or the infrared range, characterised in that it contains at least: a. one monomer which is polymerisable by free radical initiation, b. one compound which can be oxidised by photosensitisation to yield a chemical species which, under the action of a radiation of appropriate wavelength, releases initiation radicals for the polymerisation of the monomer a, c. A photosensitising agent for the reaction of b which absorbs in the visible or the infrared range. LA PRESENTE INVENTION CONCERNE UN MILIEU D'ENREGISTREMENT DE SIGNAUX LUMINEUX DANS LE VISIBLE OU L'INFRAROUGE, CARACTERISE EN CE QU'IL CONTIENT AU MOINS:A.UN MONOMERE POLYMERISABLE PAR AMORCAGE RADICALAIRE,B.UN COMPOSE OXYDABLE PAR PHOTOSENSIBILISATION POUR FOURNIR UNE ESPECE CHIMIQUE QUI, PAR ACTION D'UN RAYONNEMENT DE LONGUEUR D'ONDE APPROPRIEE, LIBERE DES RADICAUX D'AMORCAGE POUR LA POLYMERISATION DU MONOMERE A,C.UN PHOTOSENSIBILISATEUR POUR LA REACTION DE B ET ABSORBANT DANS LE VISIBLE OU L'INFRAROUGE.
