REFLECTIVE ARTICLE AND METHOD FOR THE PREPARATION THEREOF

WIPO Patent Application WO2005015272

A3

A reflective article (10) useful, for example, in automotive headlights includes a substrate (20), a reflective metal layer (30), and a haze-prevention layer (40) between the substrate and the reflective metal layer. The substrate (20) includes an amorphous thermoplastic resin having a heat distortion temperature of at least about 140 °C, density less than 1.7 grams per milliliter, and an organic volatiles content less than 1,000 parts per million measured according to ASTM D4526. The haze-prevention layer (40) includes a material having a volume resistivity of at least 1x10<-4> ohm-centimeters and a tensile modulus of at least about 3x10<5> pounds per square inch. The article resists hazing of the reflective layer at elevated temperatures.
