A process for preparing benzotriazolyl-alkylene bisphenol compounds which comprises reacting a 2-hydroxyphenylbenzotriazole and a 2,4-substituted phenol with an aldehyde in the presence of a basic catalyst and an amine compound; benzotriazolyl-alkylene bisphenol compounds obtained by the process; and stabilized organic materials containing the resulting benzotriazolyl-alkylene bisphenol compounds in an amount of 0.01-10 percent by weight. It is possible to prepare the benzotriazolyl-alkylene bisphenol compounds at a high yield, and organic materials can be effectively stabilized with the resulting compounds.
