A coating liquid containing a polyurethane dispersion and a water-dispersible polyisocyanate is applied to the laminated film 1 having the base material 2, the polyurethane layer 3 laminated on the base material 2, and the metal vapor deposition layer 4 laminated on the polyurethane layer 3 on the base material 2 and allowed to dry to obtain a polyurethane layer 3, the polyurethane dispersion containing a polyurethane resin obtained by the reaction of an isocyanate group terminated prepolymer and a chain extender, the isocyanate group terminated prepolymer It is obtained by the reaction of a polyisocyanate component containing xylylene diisocyanate and/or hydrogenated xylylene diisocyanate and a polyol component containing a diol having 2 to 6 carbon atoms, and active hydrogen group-containing compounds containing hydrophilic groups. |
