Definitions

  • the present invention relates to a coating composition
  • a coating composition comprising an oxidatively drying coating binder and a chelating ligand according to the following formula I:
  • A1 and A2 both are an aromatic residue.
  • R1 and R3 are covalently bonded groups, for example hydrogen or an organic group.
  • R2 is a divalent organic radical.
  • the chelating ligand can form a metal complex having a catalytic effect on the curing of oxidatively drying polymers, in particular alkyd resins.
  • US 3,956,211 discloses an alkyd based composition with a compound similar to that of formula I including a divalent lead ion, a zirconium ion or a divalent ion of a metal of the first transition group, except for nickel.
  • R1 and R3 are hydrogen. The effectiveness of these siccatives proved to be moderate.
  • EP-A 1 114 836 discloses the use of compounds of formula I for the preparation of resins for urushi lacquers by oxidative polymerization of phenol-functional vegetable oils.
  • the object of the invention is to improve the effectiveness of such chelating compounds.
  • the object of the invention is achieved by a coating composition according to the opening paragraph, wherein at least one solubilizing group is covalently bonded to the compound of formula I. It has been found that by improving the solubility of the compound, its effectiveness is increased substantially as well. Although it was to be expected that the presence of a solubilizing group, typically having an electron-inductive effect, would disturb the chelate function, it has been found that the catalyzing effect is better than with prior art siccatives.
  • non-polar solubilizing groups When used for compositions based on organic solvents, non-polar solubilizing groups are preferred. Suitable examples of such non-polar groups are aliphatic groups having at least four carbon atoms. Optionally, these groups may be branched alkyl groups, such as tert. butyl groups.
  • the solubilizing group can be covalently bonded to A1 and/or A2 and/or can be R1 , R2 and/or R3. Preferably, both aromatic groups are provided with a solubilizing group.
  • polyalkylene oxide groups such as polyethylene oxide or polypropylene oxide groups, are preferred.
  • A1 and/or A2 are aromatic groups, for example derived from benzene or naphthalene, optionally substituted, e.g., with electron donating groups.
  • A1 and/or A2 may be a heterocyclic aromatic group, derived from, for example, pyridine or quinoline.
  • R2 can be a linear, branched, or cyclic organic compound, such as ethylene, propylene, isopropylene, butylene, tert. butylene, pentylene, hexylene, a cycloalkylene, such as cyclohexylene, cycloheptylene, etc.
  • A1 , A2, R1 , R2 and/or R3 can be covalently bonded to a polymer, or to one or more further groups according to formula I.
  • a preferred embodiment is a poly-chelate having at least two groups according to formula I mutually linked by R1 and/or R3.
  • the metal ion can be a divalent ion of a metal which may for example be selected from the group of manganese, cobalt, copper, lead, zirconium, iron, lanthanium, cerium, vanadium, and calcium.
  • the metal ion can be a trivalent or higher valency ion of a metal combined with one or more counterions.
  • Suitable metals are for example manganese, cobalt, lead, zirconium, iron, lanthanium, and vanadium.
  • suitable counterions are halogen ions, octoate, benzoxy or mixtures thereof.
  • the coating composition can be solvent borne, water borne or solvent-free. If the composition is solvent borne, non-aromatic solvents are preferred.
  • a suitable solvent is for example Shellsol ® D40, available from Shell.

  • the unsaturated aliphatic compounds preferably are unsaturated fatty acids, more particularly polyunsaturated fatty acids. Examples of fatty acids comprising one equivalent of unsaturated CC bonds are myristoleic acid, palmitoleic acid, oleic acid, gadoleic acid, erucic acid, and ricinoleic acid and mixtures thereof.

  • triols examples include glycerol, trimethylol ethane, and trimethylol propane.
  • suitable polyols having more than 3 hydroxyl groups are pentaerythritol, sorbitol, and etherification products of the compounds in question, such as ditrimethylol propane and di-, tri-, and tetrapentaerythritol.
  • polycarboxylic acids can be used as building blocks for the oxidatively drying polyunsaturated condensation products.
  • suitable polycarboxylic acids include phthalic acid, citric acid, fumaric acid, mesaconic acid, maleic acid, citraconic acid, isophthalic acid, terephthalic acid, 5-tert.
  • the carboxylic acids in question may be used as anhydr

Suitable isocyanates are for example diisocyanates, such as 1 ,6-hexane diisocyanate, isophorone diisocyanate, toluene diisocyanate, diphenyl diisocyanate, and dicyclo- hexylmethane diisocyanate. Triisocyanates can also be used.
  • the unsaturated groups in the oxidatively drying polyunsaturated condensation product are preferably introduced by the fatty acids, but may, alternatively or additionally, be introduced by one or more of the polyols, carboxylic acids or anhydrides or other building blocks used, such as fatty mono-alcohols.
  • the oxidatively drying polyunsaturated condensation product has pendant groups in an amount of more than 20%, preferably more than 50%, by weight of the condensation product. An amount of more than 65% is even more preferred.
  • a specific example of a suitable alkyd is the condensation product of soya oil, phthalic anhydride, and pentaerythritol.
  • the alkyd resins can be obtained by direct esterification of the constituent components, with the option of a portion of these components having been converted already into ester diols or polyester diols.
