摘要：
A photopolymer medium 10 for color hologram image recording, which is formed so that a color image having a high diffraction efficiency can be obtained by exposing the same recording layer to light at a plurality of wavelengths, includes a recording layer 14 that has a recording sensitivity to light in two wavelength regions of a wavelength λ1 and a wavelength λ2. This recording layer 14 is formed from a material in which a transmittance T1 of light at the wavelength λ1 and a transmittance T2 of light at the wavelength λ2 of the recording layer before recording are both less than 80%, T1 T1, and 10%
