Compounds which have a benzotriazole and a hindered amine moiety in the
same molecule are typified by the formula A
##STR1##
wherein at least one of G.sub.2, R.sub.1 or R.sub.2 contains a hindered
amine moiety are extremely effective light stabilizers having both the UV
absorbing activity of a benzotriazole and the light stabilizing efficacy
of a hindered amine in the same molecule. These compounds are effective
stabilizers for thermoset resin compositions, thermoplastic resin
compositions, for photographic applications, for pigmented or dyed
polypropylene, polyamide or polyester fibers, and for white, dyed, dipped,
unscented and/or scented candle wax against discoloration and fading when
incorporated therein alone or in combination with an antioxidant.
