Abstract
Abstract The addition of 2-ethyl-1-hexanol to an organometallic titanium compound dissolved in a diluent and optionally containing a lower aliphatic alcohol spreading modifier, produces a solution that can be sprayed onto a substrate and cured to form an antireflection titanium oxide coating having a refractive index of from about 2.0 to 2.2.

Claims Analysis
Total Claims: 13
Claim 1
Independent Claim
31 words
A composition comprising: an organometallic titanium compound, an inert miscible ester diluent therefore, and 2-ethyl-1-hexanol in proportions such that the composition is sprayable to form a uniform film on a substrate.
Claim 2
Dependent Claim
31 words
A composition comprising: an organometallic titanium compound, an inert miscible ester diluent therefore, and 2-ethyl-1-hexanol in proportions such that the composition is sprayable to form a uniform film on a substrate.
Claim 3
Dependent Claim
15 words
The composition according to claim 1 wherein said organometallic titanium compound is a titanium alkoxide.
Claim 4
Dependent Claim
13 words
A composition according to claim 2 wherein said titanium alkoxide is titanium isopropoxide.
Claim 5
Dependent Claim
13 words
A composition according to claim 2 wherein said titanium alkoxide is titanium ethoxide.
Claim 6
Dependent Claim
13 words
A composition according to claim 1 wherein said ester diluent is butyl acetate.
Claim 7
Dependent Claim
14 words
A composition according to claim 1 which additionally contains a lower aliphatic alcohol modifier.
Claim 8
Dependent Claim
12 words
A composition according to claim 6 wherein said lower alcohol is isopropanol.
Claim 9
Dependent Claim
91 words
A mehod of applying a uniform thin antireflection coating of titanium oxide on a substrate which comprises: spraying a composition comprising an organometallic titanium compound, an inert miscible ester diluent therefore, and 2-ethyl-1-hexanol onto said substrate, drying said composition to remove said diluent and said 2-ethyl-1-hexanol by evaporation, heating the resultant film in air at an initial temperature at about 70° C. and a final temperature of 350° to 400° C., whereby a film of titanium oxide is formed on said substrate having a refractive index of from 2.0 to 2.2.
Claim 10
Dependent Claim
91 words
A mehod of applying a uniform thin antireflection coating of titanium oxide on a substrate which comprises: spraying a composition comprising an organometallic titanium compound, an inert miscible ester diluent therefore, and 2-ethyl-1-hexanol onto said substrate, drying said composition to remove said diluent and said 2-ethyl-1-hexanol by evaporation, heating the resultant film in air at an initial temperature at about 70° C. and a final temperature of 350° to 400° C., whereby a film of titanium oxide is formed on said substrate having a refractive index of from 2.0 to 2.2.
Claim 11
Dependent Claim
17 words
A method according to claim 8 wherein said spray composition additionally contains a lower aliphatic alcohol modifier.
Claim 12
Dependent Claim
58 words
A method according to claim 8 or 9 wherein said temperature is increased in a stepwise manner whereby said film-covered substrate is heated at 70° C. for at least about 30 seconds, then at about 200° C. for at least about 30 seconds and finally at a temperature of about 400° C. for at least about 30 seconds.
Claim 13
Dependent Claim
15 words
A method according to claim 8 or 9 wherein said substrate is a silicate glass.
