Claim:
An aromatic polycarbonate resin composition comprising: an admixture comprising 40 to 99 mass % of (A) and 60 to 1 mass % of (B), wherein (A) a mixture of 60 mass % or more of an aromatic polycarbonate resin and 40 mass % or less including 0% of (1) a flowability improver which is at least one selected from an acrylonitrile-styrene resin and a terpene resin, wherein the acrylonitrile-styrene resin has a melt flow rate (MFR) of 5 g/10 min or more at 200° C. under a load of 49 N and a content of acrylonitrile segments in the acrylonitrile-styrene resin ranges from 15 to 40 mass %, and (2) an impact modifier which is a core-shell graft elastomer, wherein if present, the ratio of the flowability improver to the impact modifier is 1:0.07 to 0.7, and (B) silicate-containing inorganic filler or mixture of 35 mass % or more of silicate-containing inorganic filler and 65 mass % or less including 0% of fibrous filler; and (C) a mono- or di-ester of phosphoric acid having a polyoxyalkylene alkyl ether or polyoxyalkylene alkylaryl ether group represented by Formula (I): [R 1 —O—(C n H 2n O) m ] 3-x P(═O)—(OH) x (I) wherein R 1 represents an alkyl group having 1 to 18 carbon atoms or a substituted phenyl group having an alkyl group having 1 to 18 carbon atoms; n is 2 or 3; and x is 1 or 2, in an amount sufficient to suppress a decrease in molecular weight of the aromatic polycarbonate resin of component (A) due to the presence of component (B), and wherein the mono- or di-ester of phosphoric acid having a polyoxyalkylene alkyl ether or polyoxyalkylene alkylaryl ether group is at least one compound selected from the group consisting of polyoxyethylene (m=4 to 10) octyl ether phosphate (x=1 or 2), polyoxyethylene (m=4 to 10) nonyl ether phosphate (x=1 or 2), polyoxyethylene (m=4 to 10) decyl ether phosphate (x=1 or 2), polyoxyethylene (m=4 to 10) dodecyl ether phosphate (x=1 or 2), polyoxyethylene (m=4 to 10) tridecyl ether phosphate (x=1 or 2), polyoxyethylene (m=5 to 55) octylphenyl ether phosphate (x=1 or 2), polyoxyethylene (m=5 to 55) nonylphenyl ether phosphate (x=1 or 2), polyoxyethylene (m=5 to 55) dodecylphenyl ether phosphate (x=1 or 2), polyoxypropylene (m=4 to 10) octyl ether phosphate (x=1 or 2), polyoxypropylene (m=4 to 10) nonyl ether phosphate (x=1 or 2), polyoxypropylene (m=4 to 10) decyl ether phosphate (x=1 or 2), polyoxypropylene (m=4 to 10) dodecyl ether phosphate (x=1 or 2), polyoxypropylene (m=4 to 10) tridecyl ether phosphate (x=1 or 2), polyoxypropylene (m=5 to 55) octylphenyl ether phosphate (x=1 or 2), polyoxypropylene (m=5 to 55) nonylphenyl ether phosphate (x=1 or 2), and polyoxypropylene (m=5 to 55) dodecylphenyl ether phosphate (x=1 or 2).
