The invention relates to ultraviolet absorbers with a specific absorption range which makes them suitable for cosmetic uses. These ultraviolet absorbers correspond to the formula WHERE R1 represents a hydrogen atom or an alkyl radical, one of the symbols A1 or Z1 is a sulphonic acid function and Z1, when A1 stands for one of the above-mentioned sulphonic acid functions, represents a hydrogen atom or an alkyl group, or conversely A1 represents a hydrogen atom when Z1 stands for one of these sulphonic acid functions.
