Ink composition

A radiation-curable inkjet ink composition comprising

• a radiation curable component,
• a first ester compound consisting essentially of a condensation product of a first reactant and a second reactant, wherein the first reactant is a compound A comprising at least 3 first functional groups, and wherein the second reactant comprises at least one compound B, wherein the at least one compound B comprises a second functional group, wherein the first functional group is a hydroxyl functional group and the second functional group is a carboxylic acid functional group,
• a second ester compound consisting essentially of a condensation product of a first reactant and a second reactant, wherein the first reactant is a compound A′ comprising at least 2 first functional groups, and wherein the second reactant comprises at least one compound B′, wherein the at least one compound B′ comprises a second functional group, wherein the first functional group is a hydroxyl functional group and the second functional group is a carboxylic acid functional group,
• wherein the compound B and the compound B′ are compounds of the formula
• R—C(O)OH
• in which R is an alkyl group, an aryl group, or an alkylaryl group, wherein R has 5-30 carbon atoms, and
• wherein the first ester compound is different from the second ester compound.
