Abstract
A protective tape used for optical member comprising a plastic film base, an adhesive layer formed on one side of the plastic film base and a treated layer formed on an opposite side of the plastic film base, wherein the treated layer is formed with a treat agent comprising a release agent containing long chain alkyl group or silicone resin, and a cellulose polymer. The protective tape used for optical member is enabled to direct print with an ink on the treated layer and have a low adhesive property with the adhesive applied to an optical film.
