摘要

PURPOSE:To obtain the titled sheet easily usable at the first use, by laminating a releasing sheet to the adhesive side of a protection cover having cut lines to divide the sheet into plural parts and a strong adhesive layer on one surface and laminating a temporary bonding cover to the other surface via a weak adhesive layer. CONSTITUTION:An easily drawable thin film 2 (e.g. a polypropylene film having a thickness of 12-16mum) having dividing cut lines 4 to divide the sheet into plural parts is laminated to a silicone-coated surface 1a of a releasing sheet 1 interposing a strong adhesive layer 3. The objective sheet is obtained by laminating the above laminate with a temporary bonding cover 5 having a weak adhesive layer 6 applied to the lower face of the cover.
