Zusammenfassung:To provide a coating agent for a release film that has excellent releasability.SOLUTION: A coating agent for a release film comprises: a perfluoropolyether compound comprising a methacryloyl group and having a number average molecular weight of 4000 or more; an alkyl methacrylate comprising an unsubstituted alkyl group; and a polyfunctional monomer. With the total solid content as 100 pts.mass, the content of the perfluoropolyether compound is 0.5 pt.mass or more and 20 pts.mass or less, and the content of a mixture of the perfluoropolyether compound and the alkyl methacrylate is 10 pts.mass or more and 40 pts.mass or less.SELECTED DRAWING: None 【課題】離型性に優れた離型フィルム用コーティング剤等を提供する。【解決手段】離型フィルム用コーティング剤は、(メタ)アクリロイル基を有し、数平均分子量が4000以上であるパーフルオロポリエーテル化合物と、置換されていないアルキル基を有するアルキル(メタ)アクリレートと、多官能単量体と、を含有し、固形分全体を100質量部として、前記パーフルオロポリエーテル化合物の含有量が0.5質量部以上20質量部以下であり、前記パーフルオロポリエーテル化合物及び前記アルキル(メタ)アクリレートの混合物の含有量が10質量部以上40質量部以下である。【選択図】なし
