Method for producing mold release film for molding resin sheet
The purpose of the present invention is to provide a method for producing a release film for molding a resin sheet. A method for producing a mold release film for molding a resin sheet, the method comprising: a coating step for coating a mold release layer-forming composition on a surface layer A of a polyester film having the surface layer A, the surface layer A being a layer substantially not containing inorganic particles; the release layer forming composition at least comprises a cationic curable polydimethylsiloxane (a) and an acid generator (c); a drying step for heating and drying the polyester film coated with the release layer-forming composition, the heating and drying comprising a first drying step and a subsequent second drying step, the drying temperature T1 in the first drying step being higher than the drying temperature T2 in the second drying step; and a photocuring step in which, after the drying step, the release layer-forming composition is cured by irradiation with active energy rays.
本发明的目的在于，提供树脂片成型用脱模薄膜的制造方法。一种树脂片成型用脱模薄膜的制造方法，其具有以下工序：涂布工序，其在具有表面层A的聚酯薄膜的所述表面层A上涂布脱模层形成组合物，其中，表面层A为实质上不含无机颗粒的层，脱模层形成组合物至少包含阳离子固化型聚二甲基硅氧烷(a)和产酸剂(c)；干燥工序，其对涂布有脱模层形成组合物的所述聚酯薄膜进行加热干燥，其中，加热干燥具有第1干燥工序以及接下来的第2干燥工序，第1干燥工序中的干燥温度T1高于第2干燥工序中的干燥温度T2；光固化工序，其在干燥工序后，照射活性能量射线，使脱模层形成组合物固化。
