<P>PROBLEM TO BE SOLVED: To provide a window film for thermocompression bonding which includes an adhesive layer containing an ethylene-vinyl acetate copolymer (EVA) that is hardly deteriorative against a long-term use as a principal component, and hardly causes poor appearance therein even if subjected to a process including pressure application by a nip roll when adhered to a glass plate. <P>SOLUTION: The window film is formed by thermocompression-bonding an adhesive sheet formed of an adhesive agent composition containing EVA to one surface of a transparent plastic film where a maximum trough depth Rv (JIS-B0601(2001)) of a roughness curve of both side surfaces of the adhesive layer is 1-40 μm, and the summation of a length occupying a trough whose trough depth is 5-40 μm is 30% or lower of an evaluation length. <P>COPYRIGHT: (C)2013,JPO&INPIT |
