Abstract
A glare reducing coating for reflective-transmissive surfaces such as the glass screen of a television or CRT including a resin binder, plasticizer, solvent, and flatting agent. The resin binder is nitrocellulose or an acrylic resin or a mixture of nitrocellulose and acrylic resin, and the particular plasticizer used depends upon the choice of resin binder. Preferred plasticizers are polyesters, phthlates, and alkyds, the amount of plasticizer utilized being determined by the degree of flexibility desired for the dried coating. Silica is the preferred flatting agent, and any of a large number of common organic solvents are utilized.
Claims10
A composition for application to a reflective-transmissive surface for reducing glare therefrom that is polished by wiping with a polish comprising an organic solvent and a wax, said composition comprising:
- between about 7.59 and about 22.85% of a resin binder;
- between about 63.10 and about 90.50% of a solvent in which said resin binder is solubilized for application to the reflective-transmissive surface;
- a quantity of plasticizer compatible with said resin binder sufficient to impart flexibility to said resin binder after application to the reflective-transmissive surface and evaporation of said solvent therefrom;
- and
- between about 0.60 and about 1.60% of a flatting agent suspended in the solubilized resin binder.
A composition for reducing glare when applied to a reflective-transmissive surface comprising:
- between about 7.59 and about 29.00 weight percent of a mixture of a nitrocellulose resin and an acrylic resin;
- between about 63.10 and about 90.50 weight percent of an organic solvent;
- a plasticizer compatible with each of said nitrocellulose resin and said acrylic resin, said plasticizer being selected from the group consisting of polyesters, phthalate diesters, alkyds, and nitrocellulose, and comprising a percentage sufficient to impart flexibility to said nitrocellulose resin and said acrylic resin when dried on a reflective-transmissive surface after being solubilized in said organic solvent for application to the reflective-transmissive surface, said percentage of plasticizer ranging from about 1.00 up to about 12.45 weight percent;
- and
- between about 0.60 and about 1.60 weight percent of a flatting agent suspended therein.
