    • In a multi-color image-forming medium, a substrate is coated with a color-developing layer, which is formed as a heat-sensitive color-developing layer containing a plurality of pressure-sensitive microcapsules uniformly distributed therein. Each microcapsule is filled with a dye exhibiting a first single-color, and features a characteristic to be broken when being subjected to a predetermined pressure. The heat-sensitive color-developing layer features a characteristic to be molten when being subjected to a first temperature, so that the microcapsules can be directly subjected to the predetermined pressure. The heat-sensitive color-developing layer further features a thermal-color-developing characteristic to develop a second single-color when being subjected to a second temperature more than the first temperature.
    • 在多色图像形成介质中,基板被涂覆有彩色显影层,该显色层形成为含有均匀分布在其中的多个压敏微胶囊的热敏显色层。 每个微胶囊填充呈现出第一单色的染料,并且具有在经受预定压力时被破坏的特性。 热敏显色层具有在经受第一温度时熔融的特性,使得微胶囊可以直接受到预定的压力。 热敏彩色显影层进一步具有热显色特性,以在经受超过第一温度的第二温度时形成第二单色。
