A protective tape used for optical member comprising a plastic film base, a pressure-sensitive 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 has a structure in which a copolymer (A) including (a) an alkyl (meth)acrylate having an alkyl group with carbon numbers of 8 to 20; (b) (meth)acrylonitrile; and (c) a monomer having functional groups copolymerizable with the component (a) and the component (b), as copolymerization components, is cross-linked by a cross-linking agent. 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 pressure-sensitive adhesive applied to an optical film and have a solvent resistance.

Protective tape used for optical member

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.
