An example of a non-aqueous inkjet ink includes a phenol-formaldehyde resin; a polyvinyl butyral resin; a pigment; a perfluoropolyether surfactant, a hydroxythioether surfactant, or a combination thereof; from about 2 wt % to about 10 wt % of a C 2 to C 6 ester solvent, based on a total weight of the non-aqueous inkjet ink; and a balance of a C 1 to C 5 alcohol solvent. The phenol-formaldehyde resin in the non-aqueous inkjet ink is a C 3 to C 8 alkyl-modified phenol-formaldehyde resin. |
