INKJET INK

An inkjet ink for an offset coated medium includes: water; a colorant; a binder that is a polyurethane-based dispersion; a co-solvent; and two or more surfactants. A first surfactant has a first hydrophilic lipophilic balance (HLB) value either within a water dispersible range or within a hydrophobi...

Beschreibung
Zusammenfassung:	An inkjet ink for an offset coated medium includes: water; a colorant; a binder that is a polyurethane-based dispersion; a co-solvent; and two or more surfactants. A first surfactant has a first hydrophilic lipophilic balance (HLB) value either within a water dispersible range or within a hydrophobic range and a second surfactant has a second HLB value within a hydrophobic range. The combination of the first surfactant and the second surfactant is to adjust a surface tension of the inkjet ink to a value lower than a surface tension of the offset coated medium on which the inkjet ink is to be printed.
