This invention relates to a process for the production of substituted benzotriazoles, particularly for the production of such substituted benzotriazoles which are useful as polymerizable ultraviolet light absorbers. The invention also relates to a new benzotriazole, 2(2-hydroxy-5-isopropenylphenyl)2H-benzotriazole, which is polymerizable ultraviolet light absorber, and its preparation, and to the preparation of 2(2-hydroxy-5-vinylphenyl)2H-benzotriazole, another polymerizable ultraviolet light absorber.
