することである。DISCLOSURE OF THE INVENTION Problems to be Solved by the Invention Conventional polyolefin resins generally contain a stabilizer such as an antioxidant in order to prevent oxidative deterioration of the resin. However, phenolic compounds in antioxidants such as B
When HT (2,6-di-tert-butyl-4-methylphenol) is added to the polyolefin resin, the phenolic compound reacts with heat, light, temperature, nitrogen oxides, etc. during long-term storage, The hue of the polyolefin resin or its molded product may change from white to yellow or pink. Furthermore, when a mica-made pearl pigment is used in combination, yellowing is strongly promoted due to the effect of titanium coating the mica surface. Therefore, an object of the present invention is to provide a colored resin composition which gives a polyolefin resin colored molded product in which yellowing of the molded product is prevented during long-term storage.
