PROBLEM TO BE SOLVED: To provide a hologram recording material composition which exhibits excellent transparency and resolution, etc., the same as the conventional one and enables recording transmission type and reflection type holograms in the high efficiency of refraction. SOLUTION: This recording material composition is prepared by mixing diallylorthophthalate prepolymer 5 g, an acrylic acid adduct of 9,9-bis(4- hydroxyphenyl)fluorene glycydilether 1 g, 3,3',4,4'-tetra(tert-butylperoxyphenyl) benzophenone 3.5 g, merocyanine pigment 0.01 g, diethylsebacate 4 g and acetone 6 g at ordinary temperature. The composition is applied on a glass substrate in such a manner that the thickness after drying gets to 20 μm, solvent is removed from the coated layer under vacuum and the recording medium of a two-layer structure which is composed of the substrate and the recording layer is formed. Further, a glass substrate which is the same as above described one is covered on the recording layer and thus a photosensitive plate of a three- layer structure for hologram recording is formed. |
