Abstract
Abstract A non-aqueous polymeric dispersion of an acrylic or methacrylic polymer in a non-aqueous continuous phase having a hydrogen bonding index, δ, greater than 10, a dipole moment, μ, between 0.5 and 2.5 and a solubility parameter, δ, less than 8 dries to produce a matte or low gloss coating.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
89 words
A non-aqueous dispersion, which has the property of drying to a uniform matte finish upon application to a surface, consisting essentially of a co-polymer of an alkyl methacrylate and an alkyl acrylate and an organic liquid having a hydrogen bonding index,δ, greater than 10, a dipole moment,μ, between 0.5 and 2.5, and a solubility parameter,δ, less than 8, said co-polymer being the disperse phase and said organic liquid comprising a member selected from the group consisting of ethers and alcohols and constituting the continuous phase of the non-aqueous dispersion.
Claim 2
Dependent Claim
89 words
A non-aqueous dispersion, which has the property of drying to a uniform matte finish upon application to a surface, consisting essentially of a co-polymer of an alkyl methacrylate and an alkyl acrylate and an organic liquid having a hydrogen bonding index,δ, greater than 10, a dipole moment,μ, between 0.5 and 2.5, and a solubility parameter,δ, less than 8, said co-polymer being the disperse phase and said organic liquid comprising a member selected from the group consisting of ethers and alcohols and constituting the continuous phase of the non-aqueous dispersion.
Claim 3
Dependent Claim
19 words
A dispersion according to claim 1 wherein the disperse phase is a co-polymer of methyl methacrylate and butyl acrylate.
Claim 4
Dependent Claim
21 words
A dispersion according to claim 1 wherein the disperse phase is a co-polymer of methyl methacrylate, butyl methacrylate and butyl acrylate.
Claim 5
Dependent Claim
13 words
A dispersion according to claim 1 wherein the continuous phase is diethyl ether.
Claim 6
Dependent Claim
19 words
A dispersion according to claim 1 wherein the continuous phase is a mixture of an ether and an alcohol.
Claim 7
Dependent Claim
18 words
A dispersion according to claim 1 wherein the continuous phase is a mixture of di-n-butyl ether and ethanol.
Claim 8
Dependent Claim
28 words
A dispersion according to claim 1 wherein the continuous phase is a mixture of 73 percent by weight of di-n-butyl ether and 27 percent by weight of ethanol.
Claim 9
Dependent Claim
23 words
A non-pigmented matte coating produced by applying a dispersion according to claim 1 to a surface and allowing the dispersion to dry thereon.
