Abstract:  2-(2-Hydroxy-3-Y-5-methylphenyl)benzotriazoles were prepared by electrophilic substitution reactions. Constitutions of the prepared compounds were proved by synthesis and n.m.r. and mass spectrometry. The effect of substituents on the absorption in the near u.v. region was followed regarding the use of these compounds as photostabilizers.
