Abstract

An ABS resin composition including: (A) 100 parts by mass of an ABS resin having a total light transmittance of 70% or more; (B) 1 to 70 parts by mass of an antistatic agent including a polyether ester amide having a polyamide 12 skeleton; (C) 1 to 70 parts by mass of an acid-modified methacrylic acid-based polymer having a refractive index of 1.50 to 1.56.

Claims (8)

1. An ABS resin composition comprising:

(A) 100 parts by mass of an ABS resin having a total light transmittance of at least 70%;

(B) 1 to 70 parts by mass of an antistatic agent including a polyether ester amide having a polyamide 12 skeleton;

(C) 1 to 70 parts by mass of an acid-modified methacrylic acid-based polymer having a refractive index of 1.50 to 1.56; and

(D) a methacrylic acid-based polymer that is not acid-modified.

2. The ABS resin composition according to claim 1 , wherein a surface specific resistance of the polyether ester amide having a polyamide 12 skeleton of the component (B) is 1×10 7 Ω to 1×10 9 Ω.

3. A molded article obtained from the ABS resin composition according to claim 1 , and having a total light transmittance of 70% or more and a surface specific resistance of 1×10 11 or less.

4. The ABS resin according to claim 1 , wherein the acid-modified methacrylic acid-based polymer is a copolymer of methyl methacrylate and styrene, modified by maleic anhydride at an end thereof, and the methacrylic acid based polymer that is not acid modified is selected from polymethyl methacrylate and a methyl methacrylate copolymer containing methyl methacrylate as a main component.
