Document Type and Number:
WIPO Patent Application WO/2022/019408
Kind Code:
A1
Abstract:
The present invention relates to a thermoplastic resin composition and to a molded article thereof, and more specifically, to a thermoplastic resin composition characterized by comprising 100 parts by weight of a base resin comprising an acrylate-aromatic vinyl compound-vinyl cyan compound graft copolymer; and 0.5 to 10 parts by weight of a matting agent having a refractive index of 1.46 to 1.53, wherein Equations 1 and 2 are satisfied; and to a molded article thereof. [Equation 1] G ≤ 20 (wherein G is a gloss of a 0.15T size sheet measured at 60°by a glossmeter.) [Equation 2] Hz < Tt (wherein Hz and Tt are a haze (%) and a total light transmittance (%) of the 0.15T size sheet, respectively). According to the present invention, there may be provided a matte thermoplastic resin composition, which has excellent display readability while maintaining equivalent or superior mechanical properties, weather resistance, processability, and the like, in comparison to the conventional ASA resin, and which can be injected or extruded using a general mold, a general T-die extruder, or the like, without a separate corrosion mold. In addition, the present invention provides a molded article of the matte thermoplastic resin composition. [Representative drawing] figure 1
