<p>PROBLEM TO BE SOLVED: To provide a release film capable of preventing the lowering of tackiness caused by the transfer of a low molecular weight component contained in a pressure-sensitive adhesive to the release film. SOLUTION: The release film is constituted by laminating a release agent layer to an ionic copolymer resin layer comprising a copolymer of ethylene and mono-or di-unsaturated carboxylic acid and having a crosslinked structure partially or wholly neutralized by metal ions.</p> |
