Abstract
A charge control agent-silicone oil composition includes a silicone oil and a charge control agent, the charge control agent being covalently linked to the silicone oil or is homogenously dispersed in the silicone oil as a dispersion. A method includes reacting an electrophilically-activated silicone oil with a charge control agent, thereby covalently linking the charge control agent to the silicone oil to provide a charge control agent-functionalized silicone oil. A bio-based toner includes a resin blend that includes a petroleum based resin and a bio-based resin, a charge control agent-silicone oil, a colorant, and a silica and/or titania additive, the toner having a bio-content of greater than about 25% by weight and does not exhibit moisture sensitivity.
