Abstract

An improved way to impart antireflection properties to light transmissive substrates and, at the same time, achieve a durable surface and electrical conductivity is disclosed. A stack of at least two sputter-deposited light transmissive inorganic layers, one of which being electrically conductive and having a high index of refraction with the one above it (relative to the substrate being antireflected) having a low index of refraction, in combination with a thin lubricating overlayer comprising a solvent-soluble lubricant such as a solvent-soluble fluoropolymer can achieve this desired combination of properties.
