Abstract: Rosin esters that are both light colored and color stable are produced by reacting polyhydric alcohol with an equivalent excess of rosin, in the presence of calcium bis(monoethyl(3,5-di-tert-butyl-4-hydroxybenzyl)phosphonate.

It is preferred to include a phenol sulfide compound, such as Vultac.RTM. 2, with the calcium bis(monoethyl(3,5-di-tert-butyl-4-hydroxybenzyl)phosphonate, and to add the phosphinic acid incrementally after the acid number of the rosin and polyhydric alcohol reaction mixture has dropped to about 100. Excess rosin is preferably stripped from the product mixture at about 275.degree. C.

Abstract: The specification describes a process for making highly functionalized rosin ester resins; i.e., partially esterified rosin based resins. The resins are produced by reacting fortified rosin with a polyol at superatmospheric pressure in a closed reaction vessel while retaining at least a portion of the water formed during the esterification step in the reaction vessel, thereby limiting the reaction to a desired degree of partial esterification so that a relatively high degree of residual acid functionality is achieved in the final ester product. The process enables large scale production of resins with precise control of the degree of functionality of the resins thus produced. The products are particularly useful as binders in ink formulations.
