Non-streaking black color formulations for polycarbonate-siloxane copolymers and blends

摘要

The present invention relates to a black resin composition comprising:a polycarbonate-siloxane copolymer resin, the copolymer comprising polycarbonate units and polyorganosiloxane units wherein the median siloxane domain size is greater than 100 nanometers; anda colorant combination comprising at least one organic colorant and at least one inorganic colorant, wherein the combination of the organic and inorganic colorant results in a black molded part with an L* value of less than about 29 and C* value of less than about 1.5 (specular component included) or L* value of less than 8 and C* value of less than about 3 (specular component excluded).
