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.
