[PROBLEMS] To provide a novel ultraviolet absorber, which has an ultraviolet inhibitory activity in a wide wavelength range, that is, has a strong absorptive capacity in a UVA region and further has an absorptive capacity in a UVB region, has such a property that the ultraviolet absorptive capacity in the UVA and UVB regions increases with the cumulation of ultraviolet irradiation time, and has excellent solubility. [MEANS FOR SOLVING PROBLEMS] An ultraviolet absorber having a high ultraviolet A wave absorptive capacity comprising a novel ultraviolet absorptive compound represented by general formula I as an active ingredient: wherein-OA represents an alkoxy group.
