Abstract
A hologram recording material is provided and includes at least a sensitizing dye capable of absorbing light having a hologram recording wavelength to generate an excited state thereof, and an interference fringe-recording component capable of recording interference fringes providing a refractive index modulation by an electron transfer or an energy transfer from the excited state, in which the sensitizing dye in the hologram recording material has a molar absorption coefficient within a range of 1 to 10,000 at the hologram recording wavelength.
