Abstract
A technology for curing a photocurable resin composition by ultraviolet ray/infrared ray hybrid irradiation is provided. An infrared ray irradiation is applied at least one of before or after the application of ultraviolet ray irradiation to a photocurable resin composition, to have the photocurable resin composition cured. It becomes possible to relax the ultraviolet ray irradiation conditions for photo curing by applying an infrared ray irradiation as compared with the case in which the infrared ray irradiation is not applied, and, in particular, the scratch resistance characteristics of a cured film are significantly enhanced. Moreover, because of a combination of ultraviolet ray irradiation and infrared ray irradiation, the curing time period of a cured film can be reduced and/or stress relaxation effects can be produced. Besides, it becomes possible to control the reflectance of a cured film by varying an irradiation amount of infrared ray.
