The present invention is about screening ultraviolet (UV) rays, and more particularly, relates to a resin composition for screening UV rays, which comprises 2,2′4,4′-tetrahydroxybenzophenone as an active ingredient and can screen UV rays with a wavelength up to 400 nm; and to a fabrication method of a coating film using the resin composition. In the present invention, both a first UV screening agent and a benzotriazole ultraviolet absorbent exist in a mixed state. The first UV screening agent comprises 2,2′4,4′-tetrahydroxybenzophenone as an active ingredient, and screens UV rays with a wavelength up to 400 nm. The benzotriazole ultraviolet absorbent is to screen UV rays with a wavelength up to 370 nm. The resin composition in the present invention comprises a first UV screening agent, a second UV screening agent including the benzotriazole ultraviolet absorbent, a polyurethane adhesive, an adhesive curing agent, a curing stimulant, a curing retardant, and a solvent. |
