Polynuclear phenolic compounds (Q) with up to 20 benzene nuclei per molecule obtained by the reaction of tetrahydrobenzoxazine compound (I) with one or more phenol compound (II) or one or more another tetrahydrobenzoxazine are used as stabilizers for stabilizing inanimate organic materials against the effects of light, acid and heat. Polynuclear phenolic compounds (Q) with up to 20 benzene nuclei per molecule obtained by the reaction of tetrahydrobenzoxazine compounds of formula (I) with one or more phenol compound of formula (II) or one or more another tetrahydrobenzoxazine are used as stabilizers for stabilizing inanimate organic materials against the effects of light, acid and heat.
