PURPOSE: To efficiently develop wrinkles on the surface of a cured article to improve the adhesion thereof by irradiating an ultraviolet-curing compsn. with a far ultraviolet radiation and then with a high-pressure ultraviolet radiation while heating it. CONSTITUTION: A material a is coated with an ultraviolet-curing compsn. 1 comprising as the indispensable components an ultraviolet-polymerizable compd. having an unsatd. double bond in the molecule thereof and a radical- polymerizable photopolymn. initiator of at least 300nm in maximum absorption wavelength. Subsequently, the compsn. 1 is irradiated with a far ultraviolet radiation having a peak at a wavelength of 254nm to form a cured ultraviolet- curing compsn. 2 on the surface of the compsn. 1, which is then heated and then irradiated with a high-pressure ultraviolet radiation. |
