ABSTRACT:
Process for the manufacture of oriented sheets of thermoplastic resin which are protected against the action of ultraviolet rays by applying, to at least one of the faces of the sheet, a solution comprising at least a solvent exerting a swelling action on the resin and at least one anti-UV agent which is soluble in the solvent and causing the solvent to evaporate. The treatment is applied before the orienting step by stretching, the sheets being at a temperature favoring orientation by stretching.
