Abstract
Tris[2-hydroxy-3-(2,2,6,6-tetramethyl-4-piperidylamino)propyl] isocyanurate is useful as a light stabilizer for organic materials. A composition comprising an organic material and the isocyanurate is stable against light and also excellent in heat resistance. The isocyanurate can be produced by the reaction between tris(2,3-epoxypropyl) isocyanurate and 4-amino-2,2,6,6-tetramethylpiperidine.
