PROBLEM TO BE SOLVED: To provide a hologram recording method applicable to a high density optical recording medium, a three-dimensional display, a holographic optical element etc. and capable of making a high sensitivity, a high diffraction efficiency, a satisfactory storage property, a low shrinkage rate, a dry processing, and a multiplex recording property compatible with each other. SOLUTION: The hologram recording method comprises at least a first step of producing a latent image upon holographic exposure, and a second step of causing a polymerization due to the presence of the latent image, to form an interference fringe providing a refractive index modulation, wherein the first and second steps are dry processing; particularly, the first step is a step of producing a colored material having no absorption in a hologram reconstruction light wavelength as the latent image and the second step is a step of causing the polymerization upon irradiating the colored material latent image with a light having a wavelength different from that of the holographic exposure, to record the interference fringe as the refractive index modulation.
