Abstract
Abstract Water-borne surface-coating compositions comprise an oxidizable organic film-forming resinous vehicle and a drier system that comprises a cobalt salt-potassium salt complex and that has a total metal content of 5% to 14% by weight. The drier system may also contain other metal salts, e.g., calcium salts and zirconium salts of monocarboxylic acids.

Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
154 words
A drier system for water-borne surface-coating compositions containing oxidizable organic film-forming resinous vehicles that has a total metal content of from 5% to 14% by weight and that is a solution comprising a complex that is the product of the reaction of a cobalt salt of a monocarboxylic acid having 2 to 24 carbon atoms with a potassium salt of a monocarboxylic acid having 2 to 24 carbon atoms in amounts that will provide 2 moles of said potassium salt per mole of said cobalt salt, a calcium salt, and a zirconium salt, said calcium and zirconium salts being salts of acids selected from the group consisting of aliphatic branched-chain monocarboxylic acids having 6 to 24 carbon atoms, cycloaliphatic monocarboxylic acids having 6 to 10 carbon atoms, and mixtures thereof, in a solvent mixture that contains from 20% to 80% by weight of polar solvent and 20% to 80% by weight of non-polar solvent.
Claim 2
Dependent Claim
154 words
A drier system for water-borne surface-coating compositions containing oxidizable organic film-forming resinous vehicles that has a total metal content of from 5% to 14% by weight and that is a solution comprising a complex that is the product of the reaction of a cobalt salt of a monocarboxylic acid having 2 to 24 carbon atoms with a potassium salt of a monocarboxylic acid having 2 to 24 carbon atoms in amounts that will provide 2 moles of said potassium salt per mole of said cobalt salt, a calcium salt, and a zirconium salt, said calcium and zirconium salts being salts of acids selected from the group consisting of aliphatic branched-chain monocarboxylic acids having 6 to 24 carbon atoms, cycloaliphatic monocarboxylic acids having 6 to 10 carbon atoms, and mixtures thereof, in a solvent mixture that contains from 20% to 80% by weight of polar solvent and 20% to 80% by weight of non-polar solvent.
Claim 3
Dependent Claim
21 words
A drier system as defined in claim 1 that has a total metal content of from 8% to 12% by weight.
Claim 4
Dependent Claim
101 words
A drier system as defined in claim 1 that is a solution of a complex that is the product of the reaction of a cobalt salt of monocarboxylic acids having 8 to 12 carbon atoms with a potassium salt of monocarboxylic acids having 8 to 12 carbon atoms, a calcium salt of aliphatic branched-chain monocarboxylic acid having 8 to 18 carbon atoms, and a zirconium salt of aliphatic branched-chain monocarboxylic acid having 8 to 18 carbon atoms in a solvent mixture that contains from 40% to 60% by weight of polar solvent and 40% to 60% by weight of non-polar solvent.
