Latex particles having a reactive surfactant covalently bonded to the latex particle surface are provided. The latex particles exhibit shear stability and accurate drop placement on printed media when used in ink jet inks and in high speed ink jet printers. A latex particle is also provided having a reactive surfactant covalently bonded to the surface of the latex particle, where the latex particle has a bulk density from 0.90 g/cm

and a surface dielectric constant from 2.0 to 3.0. An ink-jet ink is provided that can comprise effective amounts of an ink vehicle, a colorant admixed in the ink vehicle, latex particles dispersed in the ink vehicle, and a reactive surfactant covalently bonded to the surface of the latex particles.
