PROBLEM TO BE SOLVED: To obtain an adhesive label for heat sensitive recording, which does not require peeling paper and which is prominent in recording characteristics as a heat sensitive recording paper. SOLUTION: An adhesive label for heat sensitive recording, which does not require peeling paper, is provided with a heat sensitive recording layer containing a basic dye and a color developing agent, a protective layer and a peeling agent layer, which are provided on the front surface of a substrate, and an adhesive agent layer, provided on the rear surface side of the substrate. In such an adhesive label for heat sensitive recording, the protective layer is formed of the principal constituents of an aqueous resin and a colloidal silica, while the peeling agent layer is formed of the mixture of polysiloxane selected from a mixture of polysiloxane containing mercapto group and polysiloxane containing a vinyl group and the mixture of polysiloxane containing a hexenyl group while the peeling agent layer cured by irradiation of radiation is applied on the protective layer. Further, in forming of the separating agent layer, 0.1-10 wt.% of silane coupling agent is added into the mixture of polysiloxane. |
