<p><P>PROBLEM TO BE SOLVED: To provide a method for manufacturing a film that can suppress resin from being attached to a mold surface when switching the resin, can transfer a surface structure of the mold to a surface of a film-like supporting body in the same manner as prior to switching of the resin while preventing the residual trace of resin from being transferred even after switching of the resin, and reduces the waste. <P>SOLUTION: The method for manufacturing film continuously supplies active energy ray-curable resin compositions by sequentially switching them from two or more resin supply means 12, 13 on a film-like supporting body 21 that is continuously fed to the mold 11, sandwiches the compositions with the supporting body 21 and the mold 11, applies the active energy ray to cure the compositions, and continuously manufactures the film. In the method for manufacturing the film, the resin composition supplied at least secondarily is supplied to the supporting body so that the active energy ray is not applied. When switching the resin, the resin composition is switched so that the total supply amount of the resin composition during supplying to the film-like supporting body and the next resin composition is constant or more. <P>COPYRIGHT: (C)2013,JPO&INPIT</p> |
