Title:
ADHESIVE SHEET MATERIAL
Document Type and Number:
Japanese Patent JPH1142731
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To eliminate a decrease in adhesive force of an adhesive layer for a long term by incorporating a soft synthetic resin sheet containing plasticizer, a shielding film for shielding migration of the plasticizer contained in the sheet, and the adhesive layer formed on the surface of the film. SOLUTION: The adhesive sheet material 2 comprises a soft synthetic resin sheet 10 containing plasticizer, a shielding film 12 connected to a surface of the sheet 10 to shield migration of the plasticizer contained in the sheet 10, and an adhesive layer 14 formed on a surface of the film 12. Thus, since the film 12 is interposed between the sheet 10 and the layer 14, even when the material 2 is exposed with high temperature, operated with load or used for a long period, the plasticizer contained in the sheet 10 is not migrated to the layer. And, solvent contained in the layer 14 is not migrated to the sheet 10 as well.
