Abstract
A clear blend of three resin components includes a first polycarbonate resin component; a second resin component of a first polyester copolymer resin derived from a cycloaliphatic diol and a cycloaliphatic dicarboxylic acid, and a third resin component of a second polyester polymer resin derived from the condensation of a cyclohexane diol with a terephthalic acid and an additional condensation reaction component selected from aliphatic or aromatic diacids or diols suitable for enhancing the clarity of said blend wherein the three component blend has a light transmission of seventy percent or greater and an elongation at break after exposure to Fuel C of forty percent or greater.
