Claims Analysis
Total Claims: 13
Claim 1
Independent Claim
123 words
A storage-stable air drying composition comprising a drying oil resin or ester and a preformed reaction product of a labile monofunctional reactant with an aluminum compound of the formula ##STR4## wherein R is selected from the group consisting of isopropyl, ethoxyethyl, butoxyethyl and cyclohexyl, and each of A and B is selected from the group consisting of OR, 2-ethylhexonate, 3,5,5-trimethylhexonate, versatate, naphthenate isopropylphthalate, ethoxyethoxylmaleate, ethylacetoacetate and acetylacetonate, said reaction product containing at least one gram mole of said labile monofunctional reactant per gram atom of aluminum in said aluminum compound, wherein said labile monofunctional reactant is selected from the group consisting of lower alkanols having up to about eight carbon atoms, tert.-butyl hydroperoxide, cumenyl hydroperoxide, acetylacetone, ethylacetoacetate, water, hydrogen peroxide, and mixtures thereof.
Claim 2
Dependent Claim
123 words
A storage-stable air drying composition comprising a drying oil resin or ester and a preformed reaction product of a labile monofunctional reactant with an aluminum compound of the formula ##STR4## wherein R is selected from the group consisting of isopropyl, ethoxyethyl, butoxyethyl and cyclohexyl, and each of A and B is selected from the group consisting of OR, 2-ethylhexonate, 3,5,5-trimethylhexonate, versatate, naphthenate isopropylphthalate, ethoxyethoxylmaleate, ethylacetoacetate and acetylacetonate, said reaction product containing at least one gram mole of said labile monofunctional reactant per gram atom of aluminum in said aluminum compound, wherein said labile monofunctional reactant is selected from the group consisting of lower alkanols having up to about eight carbon atoms, tert.-butyl hydroperoxide, cumenyl hydroperoxide, acetylacetone, ethylacetoacetate, water, hydrogen peroxide, and mixtures thereof.
Claim 3
Dependent Claim
18 words
A composition in accordance with claim 1 in which said labile monofunctional reactant is a branched-chain lower alkanol.
Claim 4
Dependent Claim
15 words
A composition in accordance with claim 1 in which said labile monofunctional reactant is ethoxyethanol.
Claim 5
Dependent Claim
17 words
A composition in accordance with claim 1 in which said RO of said aluminum compound is ethoxyethoxy.
Claim 6
Dependent Claim
19 words
A composition in accordance with claim 1 in which said drying oil resin or ester is an alkyd resin.
Claim 7
Dependent Claim
43 words
A composition in accordance with claim 1 additionally containing a reactive oxirane compound having the group ##STR5## and selected from ethylene oxide, propylene oxide, epichlorohydrin, methyl glycidyl ether, phenyl glycidyl ether, glycidyl ethyl hexoate, glycidyl versatate, and epoxidized soya bean oil fatty ester.
Claim 8
Dependent Claim
48 words
A composition in accordance with claim 6 which has been reduced in acid value by adding a stoichiometric excess of said reactive oxirane compound having the group ##STR6## and heating the resultant mixture under reflux conditions, thereby esterifying the carboxy groups of said drying oil or drying ester.
Claim 9
Dependent Claim
23 words
A composition in accordance with claim 1 in which there is present about 0.1 to 6 percent aluminum (as metal) to non-volatile component.
Claim 10
Dependent Claim
16 words
A composition in accordance with claim 8 in which said aluminum represents 0.5 to 5 percent.
Claim 11
Dependent Claim
36 words
The composition according to claim 1 in which said reaction is in equilibrium as represented by the equation ##STR7## in which R, A and B have the significance assigned and R'OH is said labile monofunctional reactant.
Claim 12
Dependent Claim
16 words
A composition in accordance with claim 1 in which said aluminum compound is aluminum monoisopropoxide monoversatate(monoisopropyl)phthalate.
Claim 13
Dependent Claim
15 words
A composition in accordance with claim 1 in which said aluminum compound is aluminum diethoxyethoxidemonoversatate.
