<p><P>PROBLEM TO BE SOLVED: To provide an optical protecting tape in which one face of a plastic film substrate is provided with an adhesive agent layer and the other side with a processing layer, enabling direct ink printing on the processing layer, and in which the processing layer is low in adhesive property to an adhesive agent to be applied to an optical film and has a solvent resistance. <P>SOLUTION: In the optical protecting tape, in which one face of a plastic film substrate is provided with an adhesive agent layer and the other side with a processing layer, the processing layer has a structure in which a copolymer (A), which contains, as a copolymer component, a monomer having a functional group copolymerizable with (a) (metha) acrylic acid alykyl ester of an 8-20C alkyl group, (b) (metha) acrylonitrile, and (c) the components of (a), (b), is cross-linked by a crosslinking agent. <P>COPYRIGHT: (C)2004,JPO&NCIPI</p> |
