<p>PROBLEM TO BE SOLVED: To provide a decolorizable color composition that exhibits a good and stable colored state when used as an image forming material, can be simply decolorized by a treatment comprising heating, contact with an organic solvent, or the like after being used in printing, setting, etc., and is stably kept in a decolorized state. SOLUTION: In a decolorizable color composition essentially consisting of a color developer, a color forming compound that forms a color by the intermolecular interaction on the color developing agent, and a decolorizing agent that intermolecularly interacts on the color developing agent with force stronger than the intermolecular interaction of the color developing agent on the color forming compound, the main component of the decolorizing agent in the decolorizable color composition before the colored state exists in a microparticulate or microphase separated state having a mean particle diameter of 1 nm to 100μm when their shapes are approximately regarded as spheres, and the main component of the decolorizing agent in the composition in the decolorized state is molecularly dispersed in the composition.</p> |
