DECOLORIZABLE IMAGE RECORDING PAPER AND FORMING AND DECOLORING METHOD OF DECOLORIZABLE IMAGE

摘要

PROBLEM TO BE SOLVED: To provide a decolorizable image recording paper, in which the formed color state of an image formed by a declorizable coloring agent is favorable and stable, on which decoloration is easily executed by a decoloration treatment by heating are brought in contact with an organic solvent or the like and the resultant decolorized state is stably maintained. SOLUTION: In the recording paper, which is the base material of the image formed by the decolorizable coloring agent consisting of at least a developer and a colorable compound, which develops color through the intermolecular interaction with the developer including a or no binder resin, the decolorizable image recording paper, onto or into at least the surface of which, a decolorizer intermolecularly interacting with the developer stronger than the intermolecular interaction between the developer and the colorable compound is adsorbed or impregnated as molecules or coated and mixed in paper-making fashion as fine particles, is heated or brought into contact with the organic solvent or the like.
