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.
