<p>PROBLEM TO BE SOLVED: To provide a UV absorption resin composition which is excellent in UV absorption, weather resistance antibacterial properties and a translucent member using it.SOLUTION: A UV absorption resin composition comprises an acrylic resin, a fluorescent dye, a UV absorber and a visible light-responsive photocatalyst. The fluorescent dye absorbs light in the wavelength region of 200-400 nm and emits light in the wavelength region of 400-500 nm. The UV absorber has a maximum absorption wavelengthλmax in the wavelength region of 350-370 nm. Relative to the solid contents of the acrylic resin of 100 pts. mass, the content of the fluorescent dye is 5-45 pts. mass, and the content of the UV absorber is 5-25 pts. mass.</p> |
