(57) [Summary] [Structure] An ultraviolet absorber containing a compound represented by Formula 1 as an active ingredient and a coating material containing the same. Embedded image (R 1 ; H, halogen, an alkyl group having 1 to 10 carbon atoms, R 2 ; H, an alkyl group having 1 to 10 carbon atoms, R 3 and R 4 ; Alkylene group having 1 to 10 carbon atoms, R 5 ~R 9; carbon number 1 (10 alkyl group, alkoxy group, aryl group having 6 to 10 carbon atoms, hydroxyl group, H, X; amide bond, urethane bond, ester bond, integer of n ≧ 0) [Effect] The ultraviolet absorber is an excellent ultraviolet ray. It exhibits an absorbing action and is excellent in weather resistance and heat resistance. When it is also used as a resin, it is stably held without causing bleeding out. In addition, the coating material can be applied in multiple layers, and exhibits excellent ultraviolet absorbing action and excellent weather resistance and heat resistance. |
