Data storage medium and method for the preparation thereof |
摘要 |
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° 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 1x10<-4 >ohm-centimeters and a tensile modulus of at least about 3x10<5 >pounds per square inch. The data storage medium resists hazing of the reflective layer at elevated temperatures.
