LAYERED ARTICLE INCLUDING SYNTHETIC POLYMER FILM HAVING ANTIMICROBIAL AND/OR ANTIVIRAL PROPERTIES, AND METHOD FOR PRODUCING THE SAME

Abstract: a method for producing a layered article including a synthetic polymer film having antimicrobial and/or antiviral properties includes: preparing a layered article including a substrate and a synthetic polymer film formed on the substrate, wherein the synthetic polymer film has, on a surface thereof, a plurality of protrusions having area equivalent circle diameters in a range of more than 20 nm to less than 500 nm when the surface is viewed in a direction normal to the synthetic polymer film; and irradiating the plurality of protrusions in the layered article with light emitted from a xenon lamp such that the amount of irradiation with light in a wavelength range of 300 nm or more to 400 nm or less is 6 mj/mor more.
