An ink comprising: (a) from 1 to 20 parts of surface treated titanium dioxide; (b) from 20 to 70 parts of viscosity modifier; (c) from 5 to 30 parts of one or more water miscible polar organic solvent(s); (d) from 0.1 to 3 parts of surfactant; (e) from 0.001 to 5 parts of biocide; (f) from 0 to 20 parts of polymer particles; (g) the balance to 100 parts water; wherein the ink has a vis cosity in the range of from 10 to 25 mPa·s when measured at 32° C. using a Brookfield spindle SOO at 3 or 12 rpm depending on whether the viscosity is < or >16 mPa·s. Also ink jet printing processes, printed substrates, ink containers and ink-jet printers. |
