Abstract

The present invention relates to an improved high-solids wood coating composition wherein said high-solids wood coating composition comprises, relative to the total weight of said high-solids wood coating composition, from 60.00 to 99.00 weight percentage of a triglyceride oil composition, wherein the triglyceride oil composition comprises, relative to the total weight of all fatty acid residues in the triglyceride oil composition, equal to or less than 15.00 wt. % of saturated fatty acid residues (SAFA) and from 30.00 to 85.00 wt. % of at least one fatty acid residue having at least three conjugated double bonds; from 0.01 to 2.00 weight percentage of at least one metal-based drying agent; from 0.50 to 10.00 wt. % of at least one acylphosphine oxide photoinitiator; at least one α-hydroxyalkylphenone photoinitiator according to general Formula (I_P2) or according to general Formula (II_P2), wherein the at least one α-hydroxyalkylphenone photoinitiator is present in an amount as determined by a weight ratio of the at least one α-hydroxyalkylphenone photoinitiator to at the least one acylphosphine oxide photoinitiator ranging from 0.5 to 10.0; equal to or less than 5.00 wt. % of at least one radically polymerizable (meth)acrylic-functionalized compound different from the compound (P1); and wherein said high-solids wood coating composition has a total solids content equal to or greater than 90.00 wt. %, relative to the total weight of said high-solids wood coating composition, and wherein the total solids content of said high-solids wood coating composition is measured according to the standard ASTM D2369 - 20.
