Abstract: The present invention is directed to a process for preparing coating compositions containing up to 100% bio-based content. The coating compositions are used for coating metal, paper and wood substrates in various applications. The process for preparing the coating composition comprises the steps of providing lignin, wherein the lignin is agglomerated and has a particle size distribution such that at least 80 wt-% of the agglomerates have a diameter within the range of from 0.2 mm to 5.0 mm, dissolving the agglomerated lignin in an organic solvent, and mixing the solution with a crosslinker to obtain a coating composition.
