PROBLEM TO BE SOLVED: To provide a kind of stabilizer composition especially applied to organic polymers to improve yellowing problems of the polymers and caused by light, and especially to provide a stabilizer composition applied to polyurethane (PU) material. SOLUTION: The stabilizer composition comprises (a) a UV absorber of a formamidine derivative, (b) a UV absorber of a benzotriazole derivative and (c) an antioxidant. The stabilizer composition improves stability of the organic polymers to prevent yellowing. COPYRIGHT: (C)2004,JPO&NCIPI
