Abstract
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.

Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
95 words
A method of improvement of light transmission through a reflective/transmissive surface comprising external surface irregularities, said method comprising first creating said surface irregularities by providing an anti-glare dispersion of polyvinyl acetate particulates and water, applying said dispersion and allowing the dispersion to dry to form a coating that reduces reflected glare at said surface, while allowing transmission of light through the surface to permit viewing of objects behind the surface, and then applying an inert liquid coating sufficiently thick to remove at least some, but not all, of the anti-glare effect of the surface irregularities.
Claim 2
Independent Claim
95 words
A method of improvement of light transmission through a reflective/transmissive surface comprising external surface irregularities, said method comprising first creating said surface irregularities by providing an anti-glare dispersion of polyvinyl acetate particulates and water, applying said dispersion and allowing the dispersion to dry to form a coating that reduces reflected glare at said surface, while allowing transmission of light through the surface to permit viewing of objects behind the surface, and then applying an inert liquid coating sufficiently thick to remove at least some, but not all, of the anti-glare effect of the surface irregularities.
Claim 3
Dependent Claim
16 words
The method of claim 1 wherein said surface is a viewing surface of an electronic screen.
Claim 4
Dependent Claim
22 words
The method of claim 1 wherein said inert liquid coating is applied and then portions thereof are removed to achieve controlled transmission.
Claim 5
Dependent Claim
41 words
The method of claim 3 wherein said inert liquid coating is applied to a thickness that covers all particulates on said surface, and said fluid coating is then removed to a thickness that exposes some, but not all, of said particulates.
Claim 6
Dependent Claim
12 words
The method of claim 1 wherein said inert fluid is a hydrocarbon.
Claim 7
Dependent Claim
