PURPOSE:To obtain a sheet-shaped hologram having an arbitrary shape by forming a hologram film on a water soluble substrate having an arbitrary surface shape, then dissolving away the substrate after the hologram formation. CONSTITUTION:A photosensitive material layer essentially consisting of a vinyl carbazole polymer is laminated on the substrate consisting of alkali halide and is subjected to exposing and development processing to form the hologram; thereafter, the substrate is dissolved away. The sheet-shaped volume phase type hologram is thereby obtd. and is usable as an ornamental material, etc., for various objects by a transfer method and sticking method.
