OA SHEET

摘要

PURPOSE: To provide an OA sheet which after recycling deteriorates little in ink printability as well as in the property of being conveyed inside a printing device and handleability by providing on a base a cover allowing easy removal of adherent materials and having a predetermined resistance value. CONSTITUTION: A cover allowing easy removal of adherent materials and made of a film composed mainly of a resin which has a hydrophilic property so that it swells with water but does not flow out and disappear and which is in solid form in air at room temperature is provided on a base. The surface electrical resistance of the cover after the cover is immersed in water for five minutes and dried for five minutes by 60 to 90 deg.C hot air is 10<5> to 10<13>Ω/ opening at 25 deg.C and at 50% RH. The surface electrical resistance is 10 to 10<5> to 10<13>Ω/-opening before immersion in water.
