Abstract
Rosin modified phenolic resins are prepared by reacting together rosin, fatty acid, phenol and aldehyde. The fatty acid may be Monomer (derived from the fatty acid dimerization process). The reaction mixture may optionally include α,β-olefinically unsaturated carboxylic acid(s) or anhydride(s), and polyol(s). The resin may be dissolved in a solvent to form a varnish. The resin may be used as a component of inks for lithographic or gravure printing.
