Claims Analysis
Total Claims: 17
Claim 1
Independent Claim
60 words
An air-drying fatty acid-modified vinyl polymerized resin comprising moieties derived from: (i) a copolymerizable monomer containing an epoxy group, (ii) an air-drying fatty acid which esterifies through the epoxy group to form hydroxyl group(s), (iii) an isocyanate consisting essentially of a monoisocyanate which reacts, partially, with the formed hydroxyl group(s), and (iv) another copolymerizable monomer which is different from (i).
Claim 2
Dependent Claim
60 words
An air-drying fatty acid-modified vinyl polymerized resin comprising moieties derived from: (i) a copolymerizable monomer containing an epoxy group, (ii) an air-drying fatty acid which esterifies through the epoxy group to form hydroxyl group(s), (iii) an isocyanate consisting essentially of a monoisocyanate which reacts, partially, with the formed hydroxyl group(s), and (iv) another copolymerizable monomer which is different from (i).
Claim 3
Dependent Claim
52 words
An air-drying fatty acid-modified vinyl polymerized resin, comprising: (i) a copolymer of ethylenically unsaturated monomers, at least one of which contains an epoxy group, which has been esterified with (ii) an air-drying fatty acid with the resultant formation of hydroxyl group(s) which are reacted with an isocyanate consisting essentially of a monoisocyanate.
Claim 4
Dependent Claim
52 words
An air-drying fatty acid-modified vinyl polymerized resin, comprising: (i) a copolymer of ethylenically unsaturated monomers, at least one of which contains an epoxy group, which has been esterified with (ii) an air-drying fatty acid with the resultant formation of hydroxyl group(s) which are reacted with an isocyanate consisting essentially of a monoisocyanate.
Claim 5
Dependent Claim
18 words
A resin of claim 1 or 2, wherein the ethylenically unsaturated monomer containing an epoxy group is glycidyl(meth)acrylate.
Claim 6
Dependent Claim
25 words
A resin as in claim 1 or 2, wherein the fatty acid is obtained from dehydrated castor oil, linseed oil, soya oil or tung oil.
Claim 7
Dependent Claim
34 words
A resin as recited in claim 1 or 2, wherein the copolymer is reacted with the fatty acid in an equivalent ratio of 0.1 to 0.9:1 of the acid group to the epoxy group.
Claim 8
Dependent Claim
23 words
A resin as recited in claim 1 or 2, wherein the isocyanate is a monoisocyanate which is phenyl, cyclohexyl, n-butyl or t-butyl isocyanate.
Claim 9
Dependent Claim
35 words
A resin as recited in claim 1 or 2, wherein the formed hydroxyl group is reacted with a monoisocyanate in an equivalent ratio of 0.15 to 0.85:1 of the isocyanate group to the hydroxyl group.
Claim 10
Dependent Claim
33 words
An air-curable composition which comprises: (i) an air-drying fatty acid-modified vinyl polymerized resin of claim 1 or 2, (ii) a metal drier, and (iii) a drier activator comprising a coordination complex of titanium.
Claim 11
Dependent Claim
12 words
A composition of claim 8, wherein the drier is a cobalt salt.
Claim 12
Dependent Claim
15 words
A composition of claim 8, wherein the coordination complex of titanium is titanium II diisopropyldiacetoacetonate.
Claim 13
Dependent Claim
45 words
A composition of claim 8, wherein the metal drier and drier activator are present in an amount by weight metal which is sufficient to effect drying of the composition; the percent by weight is based on the total weight of resin solids of the composition.
Claim 14
Dependent Claim
62 words
A composition of claim 8, wherein the metal salt drier is cobalt which is present in an amount of at least 0.0025 percent by weight, and the drier activator is titanium II diisopropyldiacetoacetonate which is present in an amount of at least 0.1 percent by weight, the percent by weight is based on the total weight of resin solids of the composition.
Claim 15
Dependent Claim
20 words
A coating composition as recited in claim 8, having a resin solids content of 60 to 90 percent by weight.
Claim 16
Dependent Claim
39 words
A process for preparing a decorative or protective coating for a substrate, said process comprises: (1) applying to the substrate a composition as recited in claim 8, followed by curing the substrate by drying at ambient temperature, or baking.
Claim 17
Dependent Claim
13 words
An article of matter which is prepared by the process of claim 14.
