    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 1×10−4 ohm-centimeters and a tensile modulus of at least about 3×105 pounds per square inch. The data storage medium resists hazing of the reflective layer at elevated temperatures.

    摘要: 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° 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 1×10−4 ohm-centimeters and a tensile modulus of at least about 3×105 pounds per square inch. The article resists hazing of the reflective layer at elevated temperatures.

    摘要: A novel class of soluble organic nitrogen compounds which produces various colors when dissolved in organic liquid solvents. These dyes produce a color from blue to red if the organic liquid medium has a neutral or basic pH which reversibly changes to yellow if the liquid medium has an acid pH. The color variation can also serve as an indication of solvent polarity.
