  • Patent number: 10144827
    Abstract: A thermoplastic composition including a polyaryl ester, a polymer different from the polyaryl ester, and a phthalone compound according to the formula (I) wherein Z1 represents the atoms necessary to complete a 9- to 13-membered single or fused aromatic ring structure, Z2 represents the atoms necessary to complete a pyridine or quinoline ring, each R1 and each R2 are independently halogen, an alkyl group, an aryl group, a heterocyclic group, an alkoxy group, an aryloxy group, an aromatic or aliphatic thioether group, an aromatic or aliphatic carboxylic acid ester group, or an aromatic or aliphatic amide group, a is 0 to 6, b is 0 to 4, n is 1 or 2, and X is present only if n=2 and is a single bond or a divalent organic radical bonded to the Z1 ring structure through an ether, ketone, or thio linkage.

  • Patent number: 7728056
    Abstract: Disclosed are resinous compositions comprising a colorant combination comprising at least one inorganic infrared reflecting pigment and at least one organic colorant, wherein the combination of inorganic pigment and organic colorant results in a molded part with an L* value of less than about 30 with specular component included, and a heating build-up (HBU) as measured according to ASTM D4803-89 of less than about 34° C. A method to make such compositions is also an embodiment of the invention as are articles made from such compositions.
