Subject plate for recording holograms, holograms-making method, and hologram-recorded article

A hologram-making method wherein a photosensitive material film, which is in close contact with a subject plate for recording a hologram, is irradiated with light to record the hologram therein, said photosensitive material film being comprised of a photosensitive material having support film layers located on both sides thereof, said method comprising the steps of:

• releasing one support film layer from said photosensitive material film with a combined application/release head moving in a first direction while said photosensitive material film is fed in a feeding direction,
• successively applying said photosensitive material film onto said subject plate with said combined application/release head with the thus exposed side of said photosensitive material film located not opposite to said subject plate, while the other side of said photosensitive material film opposite to said subject plate is squeezed by a roller of said combined application/release head against said subject plate,
• irradiating said photosensitive material film with light while said photosensitive film and said combined application/release head are stationary,
• successively releasing a leading end of said photosensitive material film from said subject plate with said combined application/release head moving in a direction opposite to the first direction while said photosensitive material film is retained by said roller,
• successively applying a color tuning film onto an exposed surface of the thus released photosensitive material film, thereby widening a bandwidth of diffracted wavelength, and
• rolling said photosensitive material film.
