Abstract
A photosensitive material, suitable for image-wise recording, e.g., holographic recording of data or other information, comprises an organic species in an organic-inorganic matrix, the organic species comprising a material having a refractive index which changes upon exposure to actinic radiation. The organic-inorganic matrix may be an organically modified glass. The photo-sensitive material may be made using the sol-gel process.

A photosensitive material comprising a host matrix formed by an inorganic network and an organic-inorganic net-work interpenetrating each other, the host matrix containing at least one organic species having a refractive index which changes upon exposure to actinic radiation.
A process of making a photosensitive material comprising the steps of forming a host matrix comprising an inorganic network and an organic-inorganic network interpenetrating each other, the host matrix containing at least one organic species having a refractive index that changes on exposure to actinic radiation.
