CA 2067297

Photosensitive films which are protected by suitable barrier materials are described. The protective barriers form a film on at least one surface of a layer of photosensitive material and the protective barriers are water soluble polymeric materials having a refractive index similar to the refractive index of the recording film. The protected photosensitive recording films are useful for recording high efficiency holograms on photopolymers in the presence of index matching immersion oils.

Film photosensible protégé par des matériaux barrières adéquats. Ces matériaux forment un film sur au moins une surface d'une couche du matériau photosensible et consistent en des polymères solubles dans l'eau présentant un indice de réfraction semblable à celui du film enregistreur. Le film enregistreur photosensible protégé convient à l'enregistrement d'hologrammes à haut rendement sur des photopolymères en présence d'huiles d'immersions présentant le même indice de réfraction.
