Patent ID: 7723418

Claim:
An antistatic resin composition, comprising a thermoplastic resin (A), an antistatic agent (B) having a hydrophilic chain and at least one additive (C) selected from the group consisting of alkali metal salts of organic acids, alkaline earth metal salts of organic acid, anionic surfactants, cationic surfactants and amphoteric surfactants, wherein a difference between refractive indexes of the thermoplastic resin (A) and the antistatic agent (B) is not more than 0.02, and the antistatic agent (B) comprises at least one material selected from the group consisting of (B1) and (B2), wherein (B1) is a polyetheresteramide derived from a polyamide (b11) having a number average molecular weight of 200-5000 and an alkyleneoxide adduct (b12) of bisphenol that has a number average molecular weight of 300-5000; (B2) is a block polymer which has a structure such that blocks of a polyolefin (b21) and blocks of a hydrophilic polymer (b22) having a volume resistivity of 10 5 -10 11 Ω·cm are bonded together alternately and repeatedly via at least one bonding mode selected from the group consisting of ester bonding, amide bonding, ether bonding, imide bonding and urethane bonding; and (B1) and (B2) are prepared in presence of the at least one additive (C).
