A reversible thermosensitive coloring recording method for producing multi-color images by use of a reversible thermosensitive coloring recording medium which is composed of a support and a reversible thermosensitive coloring recording layer containing a plurality of reversible thermosensitive coloring compositions, each coloring composition being independently present separated from the other coloring compositions, and capable of reversibly forming a color development state with a different color in a predetermined color development temperature range, and a decolorization state in a predetermined decolorization temperature range by the application of heat thereto and maintaining the above two states at room temperature, the decolorization temperature range being located lower in terms of temperature than the color development temperature range therefor, comprises the steps of: temporarily applying heat to the recording medium to a color development temperature at which at least two of the coloring compositions are colored or to a temperature higher than the color development temperature to obtain a mixed coloring state, and decolorizing at least one of the coloring compositions which have been colored, thereby producing multi-color images.
一种可逆热敏着色记录方法,用于通过使用可逆热敏着色记录介质来产生多彩图像,该介质由支撑体和可逆热敏着色记录层组成,该层包含多种可逆热敏着色成分,每种着色成分均独立存在于其他着色成分之外,并能够在预定的着色温度范围内与不同颜色形成可逆的着色状态,以及在预定的脱色温度范围内通过加热而形成可逆的脱色状态,并在室温下维持上述两种状态,其中脱色温度范围低于其着色温度范围,该方法包括以下步骤:将记录介质暂时加热到至少两种着色成分被着色的着色温度或者高于着色温度的温度,以获得混合着色状态,然后脱色至少一种已着色的着色成分,从而产生多彩图像。
