Apparatus for curing photo-curable composition

摘要

A photo-curable composition with high covering power provides the coating film with a glossy smooth surface when such composition is exposed firstly to light radiation having wavelengths of from about 350 nm to about 460 nm, and then to light radiation having wavelengths of from about 230 nm to about 400 nm with a specific ratio of the intensity of the former light radiation to the intensity of the latter light radiation.
