Abstract: An example of a thermal inkjet fluid composition includes a water soluble photoacid generator having substantially no absorbance at a radiation wavelength ranging from about 360 nm to about 410 nm, a water soluble polymeric sensitizer having absorption at the radiation wavelength ranging from about 360 nm to about 410 nm, a polymeric binder, and a balance of water. The water soluble polymeric sensitizer includes a functionalized aromatic chromophore moiety, a polyether chain, and an amide linkage or an ether linkage attaching one end of the polyether chain to the functionalized aromatic chromophore moiety.

Abstract: An example dye sublimation inkjet ink set includes a first dye sublimation inkjet ink and a second dye sublimation inkjet ink. The first dye sublimation inkjet ink includes a disperse dye colorant dispersion including a first disperse dye having absorption at a radiation wavelength ranging from about 360 nm to about 410 nm; an additive to absorb energy at the radiation wavelength ranging from about 360 nm to about 410 nm and to dissipate at least some of the absorbed energy as fluorescence; a co-solvent; and a balance of water. The additive is selected from the group consisting of a compound containing from 3 to 5 fused benzene rings and and a coumarin derivative. The second dye sublimation inkjet ink includes a disperse dye colorant dispersion including a second disperse dye having less absorption at the radiation wavelength than the first disperse dye; a co-solvent; and a balance of water.

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)).

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.
