Abstract
Abstract A coating composition for the pyrolytic deposition of metal oxide films is disclosed comprising an organometallic coating reactant, a high boiling point organic compound which modifies the rate of film formation and decreases the particle size of the metal oxide, and, preferably, a nonflammable halocarbon-containing solvent.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
52 words
In a method for forming metal oxide films by contacting a hot surface with a coating composition comprising an organometallic coating reactant which thermally decomposes to a metal oxide, the improvement which comprises adding to said coating composition a relatively nontoxic organic compound having a boiling point of at least 200° C.
Claim 2
Dependent Claim
52 words
In a method for forming metal oxide films by contacting a hot surface with a coating composition comprising an organometallic coating reactant which thermally decomposes to a metal oxide, the improvement which comprises adding to said coating composition a relatively nontoxic organic compound having a boiling point of at least 200° C.
Claim 3
Dependent Claim
17 words
A method according to claim 1, wherein the organometallic coating reactant is a transition metal beta diketonate.
Claim 4
Dependent Claim
31 words
A method according to claim 1, wherein the coating composition comprises a solvent for the organometallic coating reactant and the organic compound has a boiling point substantially higher than said solvent.
Claim 5
Dependent Claim
20 words
A method according to claim 3, wherein said solvent comprises a halogenated hydrocarbon containing from 1 to 4 carbon atoms.
Claim 6
Dependent Claim
24 words
A method according to claim 4, wherein the organic compound is selected from the group consisting of benzyl alcohol, benzyl benzoate and phenylpropyl alcohol.
Claim 7
Dependent Claim
54 words
In a solventless method for forming metal oxide films by contacting a hot surface with a coating composition comprising an organometallic coating reactant which thermally decomposes to a metal oxide, the improvement which comprises adding to said coating composition a relatively nontoxic organic compound having a boiling point of at least about 200° C.
Claim 8
Dependent Claim
54 words
In a solventless method for forming metal oxide films by contacting a hot surface with a coating composition comprising an organometallic coating reactant which thermally decomposes to a metal oxide, the improvement which comprises adding to said coating composition a relatively nontoxic organic compound having a boiling point of at least about 200° C.
Claim 9
Dependent Claim
17 words
A method according to claim 6, wherein the organometallic coating reactant is a transition metal beta diketonate.
