%X Nitration of the commercial photostabilizer Tinuvin P, 2-(21-hydroxy-5&#8242;-methylphenyl)- 2H-benzotriazole,* has been shown to yield 2-(2&#8242;-hydroxy-5&#8242;-methyl-3&#8242;-nitrophenol)-2H-benzotriazole. The anion of this nitro compound is intensely coloured and may be the cause of yellowing of polymers in which Tinuvin P has been incorporated.
