  • Phenolic-modified rosin ester printing inks
    Patent number: 4857624
    Abstract: Improved phenolic-modified rosin ester resins are disclosed. The phenolic-modified rosin ester resins comprise the reaction product of substantially unsaturated rosins with a dienophile, a phenolic compound and a formaldehyde-containing compound, which product is then esterified. The resulting composition is useful in vehicles for publication gravure printing inks, as well as in the printing inks themselves. Printing inks fabricated in accordance with the invention employing these improved phenolic-modified rosin ester resins provide prints of superior quality.

  • Printing ink resins
    Patent number: 4111916
    Abstract: Cyanoethylated polyurethanes suitable for use as hard ink resins are prepared by the steps of (1) reacting a polyol having a functionality of at least 3 with an alkyl acrylate or a cyanoethylation agent such as acrylonitrile, (2) acidifying the product adduct, and (3) reacting the remaining hydroxyl groups with a polyisocyanate and optionally at least one monofunctional reactive hydrogen-containing compound and/or a glycol to yield a urethane polymer with terminal nitrile groups at repeating branch points.
