Inks

摘要

An ink comprising: (a) 0.1 to 10 parts of a self-dispersible pigment; (b) 5 to 15 parts of a polymeric latex binder with a glass transition temperature in the range of from 0° C. to −30° C.; (c) 5 to 15 parts of one or more polar organic solvent(s) with a solubility parameter at 25° C. greater than 27.5; (d) 0 to 3 parts of an acetylenic diol surfactant; (e) 0 to 5 parts of biocide; (f) 0 to 10 parts of a viscosity modifier; (g) 0 to 5 parts of one or more organic solvents with a solubility parameter at 25° C. less than 27.5; (h) 0 to 5 parts of a cross linking agent; and (i) the balance to 100 parts water; wherein the ratio of latex binder to total solvent is in the range of from 1:3 to 3:1. Also ink jet printing processes, ink-jet ink containers, printed substrates and ink-jet printers.
