Abstract: Plastics based on polyolefins and polystyrene which, in addition to optical brighteners, additionally contain a sterically hindered heterocyclic amine. These amines, known as light stabilisers, preferably 2,2,6,6-tetraalkylpiperidine compounds, increase the whiteness compared with a plastic of the same type which contains the same amount of brightener only.
