Interpolymers of vinyl halides and vinyl esters are stabilized against light by the addition of from ,5 to 10 per cent of an aryl ester of benzoic, or a substituted benzoic, acid. Suitable esters include resorcinol disalicylate, resorcinol dibenzoate, phenyl salicylate, p-cresyl salicylate, p-cresyl benzoate, m-cresyl benzoate, o-cresyl phthalate, phenyl phthalate, o-cresyl benzoate and phenyl benzoate.
