Abstract
This invention consolidates all of the functions served by the EP toner in one macromolecule. The invention is a macromolecule of dye-polymer comprising a dye colorant copolymerized with a linking/spacing component, using well known principles of polymer chemistry. A dye/charge director component may be copolymerized with the dye colorant and the linking/spacing component simultaneously or subsequently, or it may be an intrinsic part of the dye colorant or the linking/spacing component.
