Abstract:
A composition is disclosed, comprising a polycarbonate resin, an inorganic infrared shielding additive, and carbon black, wherein an article prepared from the composition has the inorganic infrared shielding additive present at about 0.01 to about 1.0 grams per square meter, and carbon black present at about 0.001 to about 2.0 grams per square meter. The article prepared from the composition meets at least one scale requirement for European Norm EN 169 and/or EN 171, and is useful for preparing infrared shielding protective eyewear with low haze.
