Abstract:
1. An aqueous ultraviolet-curable fluid composition for use in a micro-fluid ejection device, comprising: a mixture of polymerizable poly-functional compounds including a colorant being from about 2 to about 8% by weight of the ultraviolet-curable fluid for a pigment based colorant and from about 3 to about 6% by weight of the ultraviolet-curable fluid for a dye based colorant; a photo-initiator being from about 0.1 to about 5% by weight of the ultraviolet-curable fluid, wherein the photo-initiator is substantially soluble in at least one of the polymerizable poly-functional compounds; a humectant being from about 12 to about 25% by weight of the ultraviolet-curable fluid, wherein the humectant has a boiling point of greater than about 200° C. and a viscosity of less than about 13 cps; and water being from about 40 to about 50% by weight of the UV curable fluid wherein the fluid composition is substantially devoid of volatile organic carrier fluids.
