Abstract
An ink jettable overprint composition includes at least one of a polymerizable monomer and/or a polymerizable oligomer; at least one photoinitiator; and at least one wax.
Claims21
An ink jettable overprint composition, comprising:
- at least one of a polymerizable monomer and/or a polymerizable oligomer;
- at least one photoinitiator;
- and
- from about 30.6 wt % to about 60 wt % of at least one wax selected from the group consisting of waxes functionalized with UV curable groups, crystalline polymeric waxes, and hydroxyl-terminated polyethylene waxes,
- wherein the waxes functionalized with UV curable groups are selected from the group consisting of esterified carboxylic acid-terminated polyethylene waxes functionalized with UV curable groups and esterified hydroxyl-terminated polyethylene waxes functionalized with UV curable groups;
- and
- the crystalline polymeric waxes are selected from the group consisting of aliphatic polar amide functionalized waxes, carboxylic acid-terminated polyethylene waxes, aliphatic waxes consisting of esters of hydroxylated unsaturated fatty acids, high acid waxes, and mixtures thereof.
