COATING METHOD BY UV LIGHT-CURABLE COATING COMPOSITION, SURFACE COATED RESIN FILM AND SURFACE COATED PAPER

摘要

PROBLEM TO BE SOLVED: To provide a coating method by a UV light-curable coating composition having excellent adhesion property, injuring-proof property, contamination-proof property, alkali-resistance property, acid-resistance property, hot water-resistance property and weather-resistance property, and a surface coated resin film and paper obtained by using this.;SOLUTION: In the coating method by the UV light-curable coated composition, a curing method of the UV light-curable coated composition comprises a step (1) for coating the UV light-curable coating composition and a step (2) for irradiating with an electro-magnetic wave. The UV light-curable coating composition contains a UV light absorbent having an absorption area at a wavelength of 300-400 nm. The above step (2) comprises a step (2-1) for irradiating with the electro-magnetic wave in which a relative output ratio of wavelength area of 400-410 nm/wavelength area of 250-260 nm is 1.1 or more; and a step (2-2) for irradiating with the electro-magnetic wave in which a relative output ratio of wavelength area of 400-410 nm/wavelength area of 250-260 nm is 0.7 or less.;COPYRIGHT: (C)2005,JPO&NCIPI
