  • Patent number: 11117409
    Abstract: A stereoscopic image forming method forms a color stereoscopic image on a recording medium having a thermal expansion property. The stereoscopic image forming method includes the steps of: fixing a color image on the thermally expandable recording medium using a color material; and irradiating the fixed color image with light of a light source having a maximum emission wavelength in a wavelength range of 280 to 780 nm. This light is absorbed by a compound contained in the color material to generate heat of the compound.
