O,O-Bis(aryl)amidothiophosphates, useful as light stabilizers in polyolefins, are those having the formula: ##EQU1## wherein: R is hydrogen, alkyl of 1-12 carbons, or halogen; Ar is phenyl or naphthyl; n is 1 or 2; and R' and R', which may be the same or different, are each selected from the group consisting of hydrogen, alkyl of 1-18 carbons, 2,2,6,6-tetramethyl-4-piperidyl, cycloalkyl of 5-6 carbons or both R' and R', together with the N to which they are attached, form a morpholino or piperidino ring. Such compounds are made by reacting PSCl.sub.3 with two moles of a phenol and then the product thereof with an amine.
