PURPOSE:To improve heat resistance and to prevent a recording sheet for a printer from curling by forming the materials of the record holding layer and an adhesive protective layer of the sheet having a 3-layer structure of the holding layer, an adhesive layer and the adhesive protective layer. CONSTITUTION:An OHP sheet 1 is composed of a record holding layer 2, an adhesive layer 3 and an adhesive protective layer 4. The layer 2 is transparent, and its material is of polyethylene terephthalate(PET). Acrylic adhesive is employed as the layer 3. PET of one side sand mat processing is used as the layer 4. Since the materials of the holding and the protective layers of the sheet are equalized to set the thermal expansion coefficients of the materials to the same, the sheet is not curled. |
