The same procedure as in Example 7 was repeated, except that 2-nitro-2'-hydroxy-5'-t-butylazobenzene 15.0 g was replaced by 2-nitro-2'-hydroxy-5'-t-octylazobenzene 17.7 g, thus producing 13.7 g of 2-(2'-hydroxy-5'-t-octylphenyl)benzotriazole having a melting point of 103° to 105° C. at the yield of 85.0%.
