Patent ID: 7728056

Claim:
A weatherable composition comprising: (i) at least one resin selected from the group consisting of (i-a1) an acrylonitrile-styrene-acrylate (ASA) graft copolymer, (i-a2) an acrylate-modified ASA, (i-b1) a copolymer comprising carbonate structural units derived from bisphenol A and ester structural units derived from a mixture of isophthalic acid, terephthalic acid, and resorcinol, (i-b2) a copolymer comprising carbonate structural units derived from bisphenol A and dimethyl siloxane structural units, (i-c1) a blend comprising a bisphenol-A polycarbonate and a polyester selected from the group consisting of poly(butylene terephthalate), poly(ethylene terephthalate), poly(cyclohexanedimethanol-ethylene glycol terephthalate), poly(cyclohexylenedimethylene-cyclohexanedicarboxylate), and a polyester with structural units derived from a mixture of isophthalic acid, terephthalic acid, and resorcinol; and (i-c2) a blend comprising a bisphenol-A polycarbonate and a rubber modified thermoplastic resin selected from the group consisting of ABS, ASA, and MMA-ASA; and (ii) a colorant combination consisting of an inorganic infrared reflecting pigment and at least two organic colorants, wherein the inorganic infrared reflecting pigment is selected from the group consisting of a chromium iron oxide, a black spinel, and chrome iron nickel black spinel, and is present in an amount greater than or equal to about 0.02 parts per hundred parts resinous components by weight (phr), and wherein the organic colorants consist of Solvent Green 3, Solvent Red 135, and optionally at least one colorant selected from the group consisting of Solvent Violet 13, Pigment Blue 15:4, Pigment Black 31, and Disperse Violet 31/26, wherein the organic colorants are present in a total amount greater than or equal to about 0.002 phr; and wherein the combination of the inorganic pigment and organic colorant results in a molded part with a heating build-up (HBU) as measured according to ASTM D4803-89 of less than or equal to about 34° C. and an L* value of less than about 30 with specular component included or less than about 20 with specular component excluded.
