TECHNOLOGY FOCUS - ORGANIC CHEMISTRY - Preferred Component: The organic peroxide is chosen from hydroperoxide type compound, dialkyl peroxide type compound and/or ketone peroxide type compound.    TECHNOLOGY FOCUS - POLYMERS - Preferred Composition: The content of hindered amine type light stabilizer is 0.05-1.5 mass parts with respect to 100 mass parts of ethylene-vinyl acetate copolymer. The content of benzotriazole group ultraviolet absorber is 0.05-0.1 mass parts with respect to 100 mass parts of ethylene-vinyl acetate copolymer. The mass ratio of benzotriazole group ultraviolet absorber and hindered amine light stabilizer is 1:1-1:5. The content of organic peroxide is 0.2-1.5 mass parts with respect to 100 mass parts of ethylene-vinyl acetate copolymer. The content of vinyl acetate in the ethylene-vinyl acetate copolymer is 20-35 mass parts with respect to 100 mass parts of ethylene-vinyl acetate copolymer. SPECIFIC COMPOUNDS - The benzotriazole group ultraviolet absorber is 2-(2H-benzotriazol-2-yl)-6-dodecyl-4-methyl phenol, 2-(5-chloro(2H)-benzotriazol-2-yl)-4-methyl-6-tert-butylphenol and/or 2,2'-methylene bis(6-(2H-benzotriazol-2-yl)-4-(1,1,3,3-tetramethylbutyl)phenol). The hindered amine light stabilizer is bis(2,2,6,6-tetramethyl-4-piperidyl)sebacate and/or poly((6-(1,1,3,3-tetramethylbutyl)amino-1,3,5-triazine-2,4-diyl)((2,2,6,6-tetramethyl-4-piperidyl)imino)hexamethylene((2,2,6,6-tetramethyl-4-piperidyl)imino)).    EXAMPLE - EVA100 (RTM: ethylene-vinyl acetate copolymer resin) (in mass parts) (100), 2,5-dimethyl-2,5-bis(t-butylperoxy)benzene (0.6), 2-(2H-benzotriazol-2-yl)-6-dodecyl-4-methyl phenol (0.1) and bis(2,2,6,6-tetramethyl-4-piperidyl)sebacate (0.1) were mixed at 70 degrees C. The resultant mixture was subjected to calender molding, and cooled, to obtain sealing film having 0.6 mm thickness. The obtained sealing film had excellent adhesiveness (15 N/cm). The laminate comprising the sealing film had difference in yellowing degree before and after ultraviolet irradiation of 0.9, and light transmittance of 3% in wavelength of 330 nm.
