To provide a hologram recording method capable of satisfying high
sensitivity and at the same time, satisfying high diffraction efficiency,
good preservability, low shrinkage percentage, dry processing and
multiplex recording properties, a hologram recording method comprises a
first step of producing a latent image upon holographic exposure, and a
second step of causing a polymerization reaction due to the latent image,
to form a interference fringe providing a refractive index modulation,
wherein the first and second steps are dry process; particularly, the
first step is a step of producing a colored material to form the latent
image and the second step is a step of causing the polymerization
reaction upon irradiating the colored material with a light having a
wavelength different from that of the holographic exposure, to form the
interference fringe providing the refractive index modulation.
