Abstract
This invention relates to an optical article having antistatic and antireflection or reflective properties, comprising a substrate having at least one main surface coated with an antireflection or reflective coating, said coating comprising at least one electrically conductive layer comprising at least 30% tin oxide (SnO) by weight relative to the total weight of the electrically conductive layer, said electrically conductive layer having been deposited by ion-assisted deposition, and said substrate having a water uptake rate equal to or greater than 0.6% by weight relative to the total weight of said substrate, the water uptake rate being measured after predrying said substrate and then storing it for 800 hours in a chamber at 50° C. under 100% relative humidity and at atmospheric pressure.
