Reduced-rosin compositions of printing inks and the resinate binders therein, and the processes of preparation thereof, are described. In said compositions, a portion of the rosin normally used in the art is replaced by Monomer, and is further reacted with α,β-unsaturated carboxylic compound, alkaline metal salt, and solvent to produce the resinate binder product. Said resinate binder may then be formulated with a colorant to produce an ink, preferably for use in publication gravure.
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.
Rosin modified phenolic resins are prepared by reacting together resin acid, fatty acid, tri- or higher-functional phenolic compound and aldehyde. The fatty acid may be Monomer (derived from the fatty acid dimerization process). The reaction mixture may optionally include a,l3-olefinically unsaturated carbonyl compounds and/or polyol. The resin may be dissolved in a solvent to form a varnish. The resin may be used as a component of printing inks, e. g. , inks for lithographic or gravure printing.
