THERMOPLASTIC RESIN COMPOSITION HAVING ABILITY TO ABSORB LIGHT WITH WAVELENGTH OF 420 nm AND MOLDED BODY THEREOF

摘要

Disclosed is a thermoplastic resin composition containing 0.1-2.0 parts by mass of an ultraviolet absorbent (B) having an absorption band at least over a range of 340-410 nm when measured in a chloroform solution and 0.005-0.25 part by mass of iron oxide particles (C) having an average primary particle size of 10-80 nm per 100 parts by mass of a transparent thermoplastic resin (A). Also disclosed is a molded body of such a thermoplastic resin composition. The thermoplastic resin composition is excellent in transparency, and has an ability to block light with a wavelength of 420 nm. This thermoplastic resin composition can be widely used in various fields such as optical fields, electrical and electronic fields, and fields of material for medical use. For example, when the thermoplastic resin composition is molded and used for sunglasses, it provides a remarkable protective effect for the eyes.
