发明名称 MAGNETIC ATTRACTION SHEET
摘要 PROBLEM TO BE SOLVED: To provide a magnetic attraction sheet for display improved in tackiness at the time of lamination of a sheet and powder falling at the time of printing. SOLUTION: The magnetic attraction sheet 1 for display is obtained by forming a magnetic layer 5 based on a ferromagnetic powder and a polymeric binder on a non-magnetic support 4, and forming a protective layer 6 based on a cellulose acetate resin on the surface of the magnetic layer 5. The thickness of the protective layer 6 is 0.5-5 μm and the glass transition temperature Tg of the cellulose acetate resin is not less than 110 deg.C. The protective layer 6 contains particles with a mean particle size of 5-20 μm in an amount of 5-20 pts.wt. per 100 pts.wt. of the cellulose acetate resin.
