Abstract
A method of controlling light transmission through a reflective/transmissive surface by first creating surface irregularities having an anti-glare effect and then applying an inert liquid coating sufficiently thick to remove at least some, but not all, of the anti-glare effect. The surface irregularities are created by applying a dispersion and allowing it to dry to form a coating that reduces reflected glare at the surface. The dispersion is a dispersion of polyvinyl acetate particulates and water or acrylic particulates and water; alternatively, the dispersion comprises a matte varnish comprising an aqueous dispersion of an acrylic resin, and an aqueous dispersion of polyvinyl acetate.
