PROBLEM TO BE SOLVED: To provide a hologram recording medium in which a full-color pattern or different patterns, depending on the observation direction or the illumination direction can be recorded and reproduced. SOLUTION: The recording medium is a pattern recording material for an image, comprising an ensemble of pixels 2 in which one of a plurality of volume type gratings 3 made of volume type holograms and different from each another, is assigned to the entire surface of at least a part of adjoining pixels 2. The recording medium is produced, by layering a volume type hologram sensitive material on a reflective computer generated hologram, allowing reproducing illumination light at a predetermined wavelength to enter through the volume type hologram sensitive material and then recording the interference fringes by the diffracted light from the computer generated hologram and the incident light in the volume-type hologram sensitive material.
