Title
(EN) ULTRAVIOLET SHIELDING RESIN COMPOSITION AND USE THEREOF
(JA) 紫外線遮断性樹脂組成物及びその利用
Abstract
(EN)

PROBLEM TO BE SOLVED: To provide an ultraviolet shielding resin composition which excels in transparency without discoloration and also can sufficiently shield ultraviolet rays in the entire wavelength region of 290-420 nm, and also excels in the heat and wet heat durability of the ultraviolet shielding performance, and can form a pressure-sensitive adhesive layer and a coated film excellent in the heat and wet heat durability of affixation performance or the coated film surface state and adhesion as well.

SOLUTION: The ultraviolet shielding resin composition comprises an acrylic copolymer (A) having a hydroxyl group and/or a carboxylic acid (anhydride) group, a reactive compound (B) capable of reacting with at least any one of the hydroxyl group and the carboxylic acid (anhydride) group, at least any one of a pyrrolidine-amide based ultraviolet absorber (c1) and a xanthone based ultraviolet absorber (c2), and an ultraviolet absorber (c3) capable of absorbing ultraviolet rays having a wavelength of 380 nm or less, and furthermore at least any one of an antioxidant (d1) and a light stabilizer (d2).
