Abstract
The object of the present invention is to provide a colored resin composition having a uniform glitter feeling, which can prevent flow mark formation. In a resin composition molded by using a thermoplastic resin composition in which glitter material is mixed into a synthetic resin, said resin molded article must have a molding ratio L/T is not less than 100, wherein T is the thickness of the molded article and L is a distance from a gate position at molding to a remotest position on the molded article, and wherein said glitter material has average particle size d of 10 μm<d≦200 μm.
Claims8
A resin molded article comprising:
- a single thermoplastic resin composition comprising glitter material mixed into a synthetic resin and being free of an inorganic reinforcing agent and a bulking agent, said glitter material being present in said thermoplastic resin composition in a concentration from at least 0.05 parts by weight to less than 4 parts by weight per 100 parts by weight of said synthetic resin,
- wherein said resin molded article has a molding ratio L/T of not less than 100, in which L is a distance from a gate position at molding to a remotest position on said resin molded article, and T is a thickness of said resin molded article;
- wherein said glitter material has an average particles size d of 10<d≦200 μm;
- and wherein said resin molded article is free from flow marks.
