Abstract
A hologram recording material is provided and has: a sensitizing dye absorbing light upon hologram exposure to generate an excited state thereof, and an interference fringes-recording component capable of causing color development reaction or discoloration by an electron or energy transfer (movement) form the excited state to record interference fringes providing a refractive index modulation. At least one of the sensitizing dye one the interference fringes-recording component is one a polymer and an oligomer.
