Thermoplastic resin composition having superior flame retardancy, coloring property and scratch-resistance

Abstract

Provided is a thermoplastic resin composition having excellent flame resistance, colorability, and scratch resistance, including: A) 100 parts by weight of a basic resin comprising 10 to 89 wt % of acrylonitrile-butadiene-styrene copolymer, 89 to 10 wt % of styrene-acrylonitrile copolymer, and 1 to 40 wt % of methylmethacrylate polymer; B) 1 to 30 parts by weight of bromoalkyl or bromophenyl cyanurate compounds; and C) 1 to 20 parts by weight of antimony compound, thereby, making it possible to provide the thermoplastic resin composition having excellent flame resistance, impact strength, scratch resistance, colorability, and surface hardness as synergy effects.
