Abstract:
1. A platen roller for conveying a thermally active adhesive sheet having a recordable surface formed on one side of a sheet-like substrate and a thermally active adhesive layer formed on the other side of the sheet-like substrate while coming in contact with the thermally active adhesive layer, the platen roller having a roller portion containing a benzotriazole-based compound that is suitable for use as a solid plasticizer in the thermally active adhesive layer of the thermally active adhesive sheet and that is trapped within the roller portion by a contact treatment which brings the surface of the roller portion into contact with the benzotriazole-based compound, the benzotriazole-based compound contained in the roller portion being present in an amount effective to prevent liberation of the solid plasticizer in the thermally active adhesive layer of the thermally active adhesive sheet when the roller portion comes in contact with the thermally active adhesive layer to thereby inhibit a drop of the adhesive force of the thermally active adhesive layer.
