Zusammenfassung:	A process comprising the steps of a) reacting in an esterification reaction (i) a plurality of different plyols with; (ii) a plurality of different polycarboxylic acids and/or precursors therefor; in a manner to retain a plurality of free hydroxy groups in the resultant polyester(s) and retain substantial amounts of un-crosslinked polyesters in the resultant product; followed by b) reacting substantially all of the free hydroxy groups present in the resultant mixture of polyesters with an acrylating agent; to form a mixture having a hydroxy (OH) number (measured using ASTM E222-73) of no mor e than about 100mg KOH/g. Use of the mixture as a composition for lithographic or flexographic inks.
