PRESSURE SENSITIVE ADHESIVE COMPOSITION EXCELLENT IN TONER FIXABILITY AND INFORMATION SHEET USING THE SAME

摘要

PROBLEM TO BE SOLVED: To provide a pressure sensitive adhesive composition having moderated peel ability and adherability of an adhesive layer coated on a substrate sheet and good in adhesiveness with a toner or an ink later written on the adhesive layer and to provide an information sheet having the adhesive layer of the pressure sensitive adhesive composition on an overlapped surface with the sub strate sheet. SOLUTION: This pressure sensitive adhesive composition is obtained by compounding a natural rubber adhesive base with silica particles which are a particulate filler having >=400 m2/g specific surface area and >=150 (mL/100 g) oil absorption volume in an amount of 5-40 pts.mass based on 100 pts.mass of the solid content of the adhesive base and is excellent in toner fixability.
