Abstract

This invention relates to a thermally and/or high-energy radiation curable waterborne or 100% solid coating with high bio-based content. The coating formulation according to the present invention is derived or partially derived from melt polycondensation of a carboxylic acid and a diol with dicyclopentadiene-maleic acid half-ester or nadic acid-maleic acid half-ester or methyl nadic acid-maleic acid half-ester.

Claims (8)

1. A dicyclopentadiene modified ester oligomer of formula (I), wherein R is a hydrocarbon group comprising 1 to 20 carbon atoms and R′″ is a hydrocarbon group comprising 1 to 20 carbon atoms

2. The dicyclopentadiene modified ester oligomer of claim 1 , wherein R comprises 6 carbon atoms.

3. The dicyclopentadiene modified ester oligomer of claim 2 , wherein R′″ comprises 10 carbon atoms.

4. A coating composition, comprising the dicyclopentadiene modified ester oligomer of claim 3 and at least one ethylenically unsaturated monomer.

5. The coating composition of claim 4 , wherein said at least one ethylenically unsaturated monomer is selected from the group consisting of styrene, p-vinyltoluene, α-methyl styrene, methyl acrylate, methyl methacrylate, diallyl phthalate, triallyl cyanurate, vinyl ether, 2-ethylhexyl acrylate (2-EHA), isobornyl acrylate (IBOA), trimethylolpropane trimethacrylate (TMPTMA), and polyetherpolytetraacrylate.

6. A coating composition, comprising the dicyclopentadiene modified ester oligomer of claim 1 and at least one ethylenically unsaturated monomer.

7. The coating composition of claim 6 , wherein said at least one ethylenically unsaturated monomer is selected from the group consisting of styrene, p-vinyltoluene, α-methyl styrene, methyl acrylate, methyl methacrylate, diallyl phthalate, triallyl cyanurate, vinyl ether, 2-ethylhexyl acrylate (2-EHA), isobornyl acrylate (IBOA), trimethylolpropane trimethacrylate (TMPTMA), and polyetherpolytetraacrylate.

8. The coating composition of claim 7 or claim 5 , further comprising a photoinitiator.
