Provided is a technique for curing a light-curing resin composition by ultraviolet/infrared hybrid irradiation. At least before or after ultraviolet irradiation on a light-curing resin composition from which volatile components have been removed by a heating process, the light-curing resin composition is cured by infrared irradiation. By the application of infrared irradiation, the ultraviolet irradiation conditions for light-curing can be relaxed in comparison to cases in which infrared irradiation is not applied and, in particular, the scratch-resistance characteristics of a cured film are markedly improved. Furthermore, the combination of ultraviolet irradiation and infrared irradiation makes it possible to reduce the curing time for the cured film and/or to bring about a stress alleviation effect. Furthermore, changing the quantity of infrared irradiation makes it possible to control the reflectance of the cured film. |
