PURPOSE:To obtain the maximum diffraction efficiency by a regenerated light projection angle according to a theory by executing a contracting treatment by a specified solvent after a developing treatmemt, when manufacturing a hologram by using a recording medium containing a polymer which contains a carbazole ring. CONSTITUTION:A recording medium is prepared by applying to a glass plate and drying a photosensitive solution containing a bridge material (example: 2, 3-bolnadion) whose main material is a polymer having a carbazole ring (example: polyvinyl carbazole) and which consists of an annular cis-alpha-dicarbonyl compound, and an sensitizer consisting of a coloring matter, etc. (example: Michler's ketone, Thiofravine). Subsequently, this recording medium is exposed, and a developing treatment is executed, and thereafter, contracting treatment is executed by using acetonitrile or methyl isopropyl ketone, by which an object hologram is obtained. This hologram is excellent in resolving property, light resistance, moisture resistance, heat resistance, etc. |
