An ultraviolet absorber contains as an effective component a compound represented by the formula: <IMAGE> wherein R1 denotes a hydrogen atom, a halogen atom or an alkyl group having 1 to 10 carbon atoms, R2 denotes a hydrogen atom or an alkyl group having 1 to 10 carbon atoms, R3 and R4 denote the same or different groups and denote an alkylene group having 1 to 10 carbon atoms, R5 to R9 denote the same or different groups and denote an alkyl group having 1 to 10 carbon atoms, an alkoxy group having 1 to 10 carbon atoms, and an aryl group having 6 to 10 carbon atoms, a hydroxyl group or a hydrogen atom, X denotes an amido bond (CONH), a urethane bond (OCONH) or an ester bond (COO), and n is an integer of n>/=0. A coating material contains the ultraviolet absorber.
