Described herein are free radically polymerizable aqueous inkjet compositions that include water, a water-soluble or water-dispersible component polymerizable by free radical polymeration, and one or more water-soluble organic solvents in compliance with following Formula I:&#x3a3;()&#x2264;&#x3c1;&#x2003;&#x2003;(I), The variables of the formula are defined herein. Also described are printed articles that include the inkjet compositions of the disclosure. The inkjet compositions dry rapidly while remaining fluid during printing, thereby avoiding clogging in the print head.

Free radical polymerizable water-based inkjet compositions

The invention provides a drop-on-demand ink jet printing apparatus for printing inks comprising water or a volatile solvent onto a continuous web substrate, the printing apparatus comprising: a print head, a chamber for retaining water or solvent vapor in the vicinity of the print head, the chamber having an inlet for the continuous web substrate and an outlet for the printed continuous web substrate, and means for feeding the continuous web substrate through the chamber inlet into the chamber, past the print head and out of the chamber outlet.
