A reflective article useful, for example, in automotive headlights includes a substrate, a reflective metal layer, and a haze-prevention layer between the substrate and the reflective metal layer. The substrate includes an amorphous thermoplastic resin having a heat distortion temperature of at least about 140&#xb0; C., a 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 includes a material having a volume resistivity of at least 1&#xd7;10ohm-centimeters and a tensile modulus of at least about 3&#xd7;10pounds per square inch. The article resists hazing of the reflective layer at elevated temperatures.

A data storage medium includes a substrate, a reflective metal layer, and a haze-prevention layer between the substrate and the reflective metal layer. The substrate includes an amorphous thermoplastic resin having a heat distortion temperature of at least about 140&#xb0; C., a 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 includes a material having a volume resistivity of at least 1&#xd7;10ohm-centimeters and a tensile modulus of at least about 3&#xd7;10pounds per square inch. The data storage medium resists hazing of the reflective layer at elevated temperatures.

Data storage medium and method for the preparation thereof

A data storage medium includes a haze-prevention layer between a heat-resistant thermoplastic substrate and a reflective metal layer. The haze-prevention layer includes a metal having a tensile modulus of at least about 15&#xd7;10pounds per square inch. The data storage medium resists hazing of the reflective layer at elevated temperatures.

Multilayer plastic composite articles comprise at least one poly (alkylene naphthalate) surface layer which is adherent to at least one surface of a substrate which is formed of a thermoplastic resin. Decorative layers can be located between the substrate and the poly (alkylene naphthalate) surface layers.

Multilayer plastic articles

Polycarbonates, such as bisphenol A polycarbonates, having end groups derived from a di-t-alkylphenol such as 3,5-di-t-butylphenol have very low electrostatic charges. They are thus useful in applications where static charge is a problem, such as automotive headlamps and optical data recording media.

Static-resistant polycarbonates having DI-t-alkylphenyl end groups

Copolycarbonates comprise structural units derived from a bisphenol such as bisphenol A, a spiro(bis)indane bisphenol such as 6,6'-dihdyroxy-3,3,3',3'-tetramethyl-1,1'-spiro(bis)indane and a polyoxyalkylene glycol such as polyethylene glycol. These copolycarbonates have high processability and are expected to have low birefringence. They are useful for the fabrication of optical disks.
