Method for producing multilayer coated film

Abstract

Embodiments of the invention provide a method for producing a multilayer coated film which involves obtaining a first layered body by forming, on a film substrate, a wet-coated film including a coating material (A) containing an active energy ray-curable resin which contains a first photopolymerization initiator and a second photopolymerization initiator, the reaction wavelengths of which differ from one another; and forming a pre-cured coated film including the coating material (A) in a dry-to-the-touch state by preliminarily curing the wet-coated film including the coating material (A), by irradiating the first layered body with active energy rays which include the reaction wavelength of the first photopolymerization initiator and do not include the reaction wavelength of the second photopolymerization initiator. The method further includes obtaining a second layered body by forming a wet-coated film including a coating material (B) on the pre-cured coated film including the coating material (A); and obtaining the multilayer coated film by fully curing the pre-cured coated film including the coating material (A) by irradiating the second layered body with active energy rays including the reaction wavelength of the second photopolymerization initiator.
