Abstract
Abstract A dispersion for coating a reflective-transmissive surface comprising a mixture of an aqueous dispersion of polyvinyl acetate resin and an aqueous dispersion of an arcylic resin. When applied to such surfaces--for example, the protective glass or plastic of an electronic screen--the coating reduces reflected glare while maintaining the quality of the image transmitted from the screen being viewed. Methods of making and using the dispersion, as well as surfaces treated with the dispersion, are also disclosed.

Claim 11
Dependent Claim
41 words
A method of making the composition of claim 1 comprising providing a matte acrylic varnish and an aqueous dispersion of polyvinyl acetate, mixing said varnish and polyvinyl acetate, thinning said mixture with an alcohol, and diluting the resulting composition with water.
Claim 12
Dependent Claim
11 words
The method of claim 10 further comprising heating the diluted composition.
Claim 13
Dependent Claim
26 words
A method of treating a reflective-transmissive surface comprising providing the dispersion of claim 1, and applying the dispersion to the surface to form a coating thereon.
Claim 14
Dependent Claim
18 words
The method of claim 12 wherein said surface is the plastic or glass protection of an electronic screen.
Claim 15
Dependent Claim
19 words
The method of claim 13 wherein said electronic viewing screen is a television screen or a computer viewing screen.
Claim 16
Dependent Claim
18 words
A viewing screen having an external reflective-transmissive surface that comprises a coating of the composition of claim 1.
Claim 17
Dependent Claim
13 words
