  • Patent number: 5410335
    Abstract: A method for recording an image on a thermal recording material in which a plurality of color-development layers are laminated, the plurality of color-development layers being adapted to develop different colors, respectively, upon supply of thermal energy thereto and to form a substantially black color when all of the plurality of color-development layers undergo color development with a substantially identical density. With respect to a portion where a color other than black is to be developed, recording is effected such that a color-development density of each of the plurality of color-development layers becomes lower than a maximum color-development density of each of the plurality of color-development layers.
