Abstract
A process for preparing a rosin ester which comprises purifying a rosin and/or a disproportionated rosin, esterifying the resulting purified rosin and/or purified disproportionated rosin with an alcohol and subjecting the esterified rosin and/or esterified disproportionated rosin to hydrogenating. The resulting rosin ester has superior color nearly equal to colorless and is excellent in various properties such as odor at heating, stability and compatibility with organic polymers.
