摘要：
The invention relates to a polypropylene resin composition which is stabilized against photo-induced oxidation. The composition comprises a hindered amine-based light stabilizer (HALS), having a molecular weight equal or below 1250; a phenolic antioxidant (PAO) with a molecular weight of equal or below 750; and a pigment. The ratio of HALS to PAO is less than 5.
