Patent ID: 8198366

Claim:
A thermoplastic resin composition, comprising: (A) a resin mixture comprising (a-1) a polycarbonate resin in an amount of 60 to 97% by mass and (a-2) a polylactic acid homopolymer in an amount of 40 to 3% by mass; and (B) a core-shell type graft rubber-like elastomer, the rubber-like elastomer being present in an amount of 0.5 to 20 parts by mass per 100 parts by mass of the resin mixture (A); wherein: component (B) is dispersed in an interface between ingredient (a-1) and ingredient (a-2), the thermoplastic resin composition does not have a pearl-like gloss; the polycarbonate resin comprises: a polycarbonate-polyorganosiloxane copolymer resin having a recurring unit of the following formula (1): where: R 1 and R 2 are each a halogen atom or a C 1 -C 8 alkyl group, m and n are each an integer of 0 to 4, when m is 2 to 4, the plural R 1 groups may be the same as or different from each other, when n is 2 to 4, the plural R 2 groups may be the same as or different from each other, and Z represents a C 1 -C 8 alkylene or C 2 -C 8 alkylidene group, a C 5 -C 15 cycloalkylene or C 5 -C 15 cycloalkylidene group, a single bond, a bond of —SO 2 —, —SO—, —S—, —O—or —CO—, or a bond of the following formula (2) or formula (2′): a recurring unit of the following formula (4): where: R 3 , R 4 and R 5 are each a hydrogen atom, a C 1 to C 5 alkyl group or a phenyl group, and p and q are each an integer of 0 or at least 1, provided that a total of p and q is an integer of at least 1; and a terminal group represented by formula (5): where: R 6 is a C 1 to C 35 alkyl group, and a is an integer of 0 to 5.
