PROBLEM TO BE SOLVED: To easily produce many heat-sensitive recording labels to easily be worked and different from one another in color at a low cost by providing a colored layer on one face or a transparent polymer film and sticking the face where the colored layer of a heat-sensitive recording body in which a heat sensitive color developing layer is provided on the opposite face to the face where the peeling layer of peeling paper is provided, through an adhesive. SOLUTION: A heat-sensitive color developing layer 5 is formed on one face of a transparent polymer film 4 as a substrate, a colored layer 3 is formed on the opposite face and an adhesive layer 2 and peeling paper 1 are successively laminated on the colored layer 3. A known transparent polymer film as before can be used as the film 4 to be used for the substrate. The peeling paper 1 and the adhesive layer 2 are not limited if they are used for a conventional peeling label. As a leuco compd., a developer and a binder constituting the color developing layer 5, known materials as before are used. A more stable recording body is obtd. by providing a protective layer 6 mainly composed of a water-soluble polymer and/or a synthetic resin emulsion on the color developing layer 5. |
