HOT MELT INK COMPOSITION COMPRISING A COPOLYESTER AND PROCESS FOR PREPARING A COPOLYESTER

WIPO Patent Application WO/2013/000761

A3

The invention relates to a hot melt ink composition comprising a copolyester, the copolyester consisting essentially of a condensation product of a first type of monomer, a second type of monomer and a third type of monomer, wherein the first type of monomer comprises at least one monomer A selected from the group of polyhydroxyl alcohols comprising X hydroxyl functional groups, wherein X ≥ 3, wherein the second type of monomer comprises at least one monomer B selected from the group of monomers being able to form an ester linkage with an alcohol and wherein the third type of monomer comprises at least one monomer C selected from the group of aromatic monocarboxylic acids. The invention further relates to a method for preparing such copolyesters and to a hot melt ink composition comprising a mixture of such copolyesters.
