Abstract
Abstract Disclosed is a coated article (201) having a substrate (221) with an adherent, abrasion resistant alkene-silane plasma reaction product coating (231). In a preferred exemplification the coating is substantially transparent to visible light and partially absorbing to ultraviolet light. The coating is a plasma assisted chemical vapor deposition deposited coating.

Claims Analysis
Total Claims: 15
Claim 1
Independent Claim
42 words
A coated article comprising: (a) a substrate; and (b) an adherent, abrasion resistant transparent coating thereon substantially amorphous and consisting essentially of a plasma assisted chemical vapor deposition deposited alkene-silane plasma reaction product of a silane, an alkene, and an oxygen source.
Claim 2
Dependent Claim
42 words
A coated article comprising: (a) a substrate; and (b) an adherent, abrasion resistant transparent coating thereon substantially amorphous and consisting essentially of a plasma assisted chemical vapor deposition deposited alkene-silane plasma reaction product of a silane, an alkene, and an oxygen source.
Claim 3
Dependent Claim
23 words
The coated article of claim 1 wherein the alkene-silane plasma reaction product is deposited from a feed stock gas comprising an unsaturated hydrocarbon.
Claim 4
Dependent Claim
28 words
The coated article of claim 1 wherein the coating has a transmissivity of 89 percent in the visible spectrum measured at a thickness of 2 to 5 microns.
Claim 5
Dependent Claim
29 words
The coated article of claim 1 wherein the coating has a transmissivity of 20 percent at a wavelength of 380 nanometers at a thickness of 2 to 5 microns.
