Abstract
The present disclosure is drawn to non-aqueous ink compositions. The non-aqueous ink compositions can include from 70 wt % to 98 wt % alcohol solvent, from 1 wt % to 6 wt % phenol-formaldehyde resin, from 1 wt % to 5 wt % tackifier, and from 1 wt % to 14 wt % organic solvent-soluble dye. The tackifier can include a shellac having an acid number from 50 KOH/g to 100 mg KOH/g or a tackifier resin having an acid number from 100 mg KOH/g to 300 mg KOH/g.
Claims15
A non-aqueous ink composition, comprising:
- from 70 wt % to 98 wt % alcohol solvent;
- from 1 wt % to 6 wt % phenol-formaldehyde resin;
- from 1 wt % to 5 wt % tackifier, wherein the tackifier includes a shellac having an acid number from 50 KOH/g to 100 mg KOH/g or a tackifier resin having an acid number from 100 mg KOH/g to 300 mg KOH/g;
- and
- from 1 wt % to 14 wt % organic solvent-soluble dye.
A printing system, comprising:
- a non-aqueous ink composition, including
- from 70 wt % to 98 wt % alcohol solvent,
- from 1 wt % to 6 wt % phenol-formaldehyde resin,
- from 1 wt % to 5 wt % tackifier, wherein the tackifier includes a shellac having an acid number from 50 KOH/g to 100 mg KOH/g or a tackifier resin having an acid number from 100 mg KOH/g to 300 mg KOH/g, and
- from 1 wt % to 14 wt % organic solvent-soluble dye;
- and
- a non-porous polymeric substrate.
A method of printing, comprising ejecting a non-aqueous ink composition onto a non-porous polymeric substrate, the non-aqueous ink compositing, comprising from 70 wt % to 98 wt % alcohol solvent, from 1 wt % to 6 wt % phenol-formaldehyde resin, from 1 wt % to 5 wt % tackifier, and from 1 wt % to 14 wt % organic solvent-soluble dye, wherein the tackifier includes a shellac having an acid number from 50 KOH/g to 100 mg KOH/g or a tackifier resin having an acid number from 100 mg KOH/g to 300 mg KOH/g.
