Zusammenfassung: | Disclosed is a thermoplastic resin composition capable of laser marking while minimizing a decrease in whiteness in a polymer resin having excellent low temperature impact resistance and a white background color. The present invention provides a thermoplastic resin composition for laser marking which comprises: (A) 60 to 99.8 wt% of a polycarbonate resin; (B) 0.1 to 20 wt% of an impact modifier having a core-shell structure; (C) 0.1 to 20 wt% of a white filler; and (D) 0.0001 to 0.005 parts by weight of a colorant with respect to 100 parts by weight of the components (A) to (C).
우수한 저온 내충격성과 백색의 배경색을 가지는 고분자 수지에서 백색도의 저하를 최소화하면서 레이저 마킹이 가능한 열가소성 수지 조성물이 개시된다. 본 발명은 (A) 폴리카보네이트 수지 60~99.8 중량%; (B) 코어-쉘 구조를 가지는 충격보강제 0.1~20 중량%; (C) 백색 충진제 0.1~20 중량%; 및 상기 (A) 내지 (C) 성분 총 100 중량부에 대하여 (D) 색료 0.00001~0.005 중량부;를 포함하는 레이저 마킹용 열가소성 수지 조성물을 제공한다. |
