    Abstract: A thermal inkjet dye sublimation ink consists of a disperse dye colorant dispersion, a co-solvent system, an additive, and a balance of water. The colorant dispersion is present in an amount ranging from about 1 wt % actives to about 7 wt % actives. The co-solvent system is present in a total amount ranging from about 12 wt % to about 25 wt %. The co-solvent system consists of glycerol present in an amount ranging from about 9 wt % to about 16 wt %, ethoxylated glycerol present in an amount ranging from 0 wt % to about 5 wt %, and a water soluble or water miscible organic solvent present in an amount ranging from 0 wt % to about 7 wt %. The additive is selected from the group consisting of a surfactant, a chelating agent, a buffer, a biocide, and combinations thereof.

    Abstract: A thermal inkjet ink includes a water-based vehicle; a colorant; and a modified siloxane surfactant including a plurality of components. Each component has a chemical formula I: Si(1+x+z)O(1+x+z+y)C(1+1+2(x+z)+j+m+y(2+n))H(6+6+6(x+z)+o+p+y(4+q)). For each component: y ranges from 2 to 4; x and z each range from 0 to 14; x+z=from 0 to 14; j, m, and n are the number of carbon atoms, respectively, in R1, R2, and R3; o, p, and q are the number of hydrogen atoms, respectively, in R1, R2, and R3. R1 is selected from H, an alkyl, and an aryl. Each of R2 and R3 is selected from H, an alkyl, an alkyl substituted with an allylic or an epoxy group, an aryl, and an aryl substituted with an allylic or an epoxy group. For some components: x+z=from 7 to 14.
