Abstract
Provided is a method of applying an electron beam curable aqueous coating material, including coating a surface of a material to be coated with the electron beam curable aqueous coating material to form a wet coating film; drying the wet coating film until a time integration value of a reciprocal of an average value of viscosities of a region from a surface of the wet coating film to a depth of one half a film thickness of the wet coating film is in a range of 0.30 (Pa·s)·min to 0.90 (Pa·s)·min, which is acquired by an electric field pick-up method, and a solid content concentration of the wet coating film is 90% by mass or greater; and curing the obtained dry coating film by irradiation with an electron beam after the wet coating film is dried.
