OPTICAL ARTICLE COATED WITH AN ANTIREFLECTION OR REFLECTIVE COATING COMPRISING AN ELECTRICALLY CONDUCTIVE FILM BASED ON TIN OXIDE, AND PRODUCTION METHO.

摘要

The invention relates to an optical article having antistatic properties and antireflection or reflective properties, comprising a substrate having at least one main surface coated with an antireflection or reflective coating. The aforementioned coating comprises at least one electrically conductive film containing at least 30% tin oxide (SnO2) by weight relative to the total weight of the electrically conductive film, said electrically conductive film having been deposited by ion-assisted deposition. The substrate has a water uptake equal to or greater than 0.6% by weight relative to the total weight of the substrate, said water uptake being measured following the predrying of the substrate and the subsequent storage of same for 800 hours in a chamber at 50°C under 100% relative humidity and atmospheric pressure.
