<P>PROBLEM TO BE SOLVED: To provide a method for manufacturing a laminate film which is excellent in the adhesion properties between the film layer containing an alicyclic structure-containing polymer or a (meth)acrylic-based resin and the urethane resin layer while keeping the characteristics of an optical material, and to provide a laminate film manufactured by this method. <P>SOLUTION: The method for manufacturing a laminate film which has a base material film having on the uppermost surface a film layer containing an alicyclic structure-containing polymer or a (meth)acrylic-based resin and a urethane resin layer, comprises a process of forming the base material film in which the surface has an average water contact angle (Da) of 20-50 degrees and a standard deviation (Ds)of the water contact angle of 0.01-5, and a process of coating a water dispersion of an aqueous urethane resin onto the base material film: and the laminate film is manufactured by this method. <P>COPYRIGHT: (C)2010,JPO&INPIT |
