    摘要： 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.

    摘要： There are provided an optical surface protection film capable of permitting even a visual inspection of a coated body having a fine roughness, such as a prism sheet, to be performed under the condition that the protection film is attached to the coated body and excelling in adhesion reliability without an optical adverse effect on the coated body, and an optical film with the surface protection film. The optical surface protection film (1) has a base material layer (10) and an adhesive layer (12) stacked on one surface of the base material layer. The surface of the base material layer (10) on the side of the adhesive layer (12) has an arithmetic surface average roughness (Ra2) of 0.65 μm or less. The other surface of the base material layer (10) has an arithmetic surface average roughness (Ra1) of 0.6 μm or more.

    摘要： The present invention provides a pressure-sensitive adhesive which can prevent electrification of a non-electrification-prevented adherend upon peeling, suppresses occurrence of peeling off even with time or via treatment under a high temperature, and is excellent in adhesion reliance, as well as an antistatic pressure-sensitive adhesive sheet, and surface protecting film using this. The pressure-sensitive adhesive composition of the present invention contains an ionic liquid, and a polymer having a glass transition temperature of Tg of 0° C. or lower as a base polymer, as well as an ethylene oxide group-containing compound and/or a surfactant.
