Abstract

Abstract A method and kit for glare control and improvement of image transmission through a reflective-transmissive surface comprising surface irregularities to control glare. A dispersion of particles is applied to the surface and allowed to dry. Then an inert fluid coating is applied to the surface to enhance clarity. A liquid dispersion comprising a flattening agent is applied to the surface and allowed to dry so that the particles and flattening agent form a transparent glare-reducing coating. An inert fluid coating is applied to sufficient thickness to remove some, but not all, of the surface irregularities created by the glare reducing coating. A method of formulating the liquid dispersion is also disclosed.

Claims Analysis

Total Claims: 19
Claim 1
Independent Claim 100 words
A method of controlling glare from a reflective-transmissive surface comprising providing a liquid dispersion comprising organic polymeric particles and a flattening agent, coating the surface with said liquid dispersion, allowing the coating to dry leaving the organic particles and flattening agent in a transparent coating at the surface, thereby creating surface irregularities that reduce 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 fluid coating sufficiently thick to remove at least some, but not all, of the anti-glare effect of the surface irregularities.
Claim 2
Independent Claim 100 words
A method of controlling glare from a reflective-transmissive surface comprising providing a liquid dispersion comprising organic polymeric particles and a flattening agent, coating the surface with said liquid dispersion, allowing the coating to dry leaving the organic particles and flattening agent in a transparent coating at the surface, thereby creating surface irregularities that reduce 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 fluid coating sufficiently thick to remove at least some, but not all, of the anti-glare effect of the surface irregularities.
Claim 3
Dependent Claim 13 words
The method of claim 1 wherein the liquid dispersion comprises acrylic resin particles.
Claim 4
Dependent Claim 13 words
The method of claim 1 wherein the liquid dispersion comprises a latice polymer.
Claim 5
Dependent Claim 13 words
The method of claim 1 wherein the liquid dispersion comprises a polyurethane dispersion.
Claim 6
Dependent Claim 12 words
The method of claim 1 wherein the liquid dispersion comprises a varnish.
Claim 7
Dependent Claim 12 words
The method of claim 1 wherein the liquid dispersion comprises a lacquer.
Claim 8
Dependent Claim 13 words
The method of claim 1 wherein the liquid dispersion comprises a co-reaction polymer.
Claim 9
Dependent Claim 13 words
The method of claim 1 wherein the liquid dispersion comprises a condensation polymer.
Claim 10
Dependent Claim 16 words
The method of claim 1 wherein said surface is a viewing surface of an electronic screen.
Claim 11
Dependent Claim 22 words
The method of claim 1 wherein said inert fluid coating is applied and then portions thereof are removed to achieve controlled transmission.
Claim 12
Dependent Claim 41 words
The method of claim 10 wherein said inert fluid 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 13
Dependent Claim 27 words
The method of claim 1 wherein the liquid dispersion comprises a latex polymer selected from acrylate, butadiene co-polymers, polystyrene, vinyl chloride, vinylidene chloride-acrylonitrile co-polymer, and vinyl pyridine.
Claim 14
Dependent Claim 17 words
The method of claim 12 wherein the butadiene co-polymer is selected from butadiene acrylonitrile and butadiene styrene.
Claim 15
Dependent Claim 11 words
The method of claim 1 wherein the dispersion comprises a polyurethane.
Claim 16
Dependent Claim 25 words
The method of claim 14 wherein the polyurethane comprises a co-reactable polyurethane, a moisture-cured polyurethane, or a urethane produced from an alphatic or aromatic isocyanate.
Claim 17
Dependent Claim 11 words
The method of claim 1 wherein said dispersion comprises an epoxy.
Claim 18
Dependent Claim 25 words
The method of claim 16 wherein said epoxy is a co-reactable epoxy-amine, an epoxy-polyamide, a coal tar epoxy, an epoxy phenolic, or an epoxy powder.
Claim 19
Dependent Claim 36 words
The method of claim 1 wherein said liquid dispersion comprises a polymer selected from alkyl, silicone, acrylic, polyester, phenoplasts, polytetrafluoroethylene, nylon, cellulose ester, a cellulose ether, amino resins, or a co-polymer of ethylene or propylene polymers.
