To provide a method for producing a laminated film having sufficiently high adhesiveness by uniformly curing an ultraviolet curable resin in high efficiency without causing the deformation of the substrate film.
The laminated film is produced by applying an ultraviolet curable resin to one surface of a substrate film (A) composed of a transparent resin to form a film (B), irradiating the film (B) at the side opposite to the coated side with ultraviolet rays at an accumulated light quantity of 50-400 mJ/cm2 to cure the UV curable resin, and irradiating the coated side of the film (B) with ultraviolet rays while keeping the temperature difference between the coated side and the uncoated side to ≤30°C to proceed the curing of the UV curable resin. The invention further relates to the production method of the laminated film.
