    Abstract: This invention comprises a single-component dendrimeric toner particle (10, 30), and methods of making and using the toner particle (10, 30) in the liquid EP process. By using dendrimeric chemistry, a dendrimeric toner particle (10, 30) may be made that has controlled content, structure and size and that includes a colorant (11), a binder, and a charge director (34). The toner particles (10, 30) made this way will have high uniformity, so that toner dispersions containing them may be made to have good stability, print performance, and quality control. The colorant (11) of choice for the toner particle is made the core (40) of the dendrimer toner particle (10, 30). Dendrons (24, 38), which are made of generations of building or polymer units (13, 16), branch out from the core (40) and include a resin or other binder molecule, for binding the colorant (11) to the paper in the EP process. One or more of the final polymer units (20), located at the terminus of the dendrons (24, 38), comprise a coordinating or chelating agent (32) for the toner charge director (34).

    Abstract: For preparing a polyether-dendrimer-alkali metal salt (a) a polyvalent core W(X) n wherein W is a polyvalent core atom which is covalently bonded to nX reactive terminal OH-groups (n≧2) is converted into its correponding alkali metal salt by reaction of the polyvalent core with alkali metal hydroxide or zero valence alkali metal, (b) the obtained salt is reacted with a molar excess of a partially protected multifunctional reagent T-(U) V m wherein U represents a multivalent moiety covalently bonded to m V protected moieties (m≧2) and to one T, a moiety capable of reacting with X to form W[(X'-T')U V m ] n , wherein X' and T' represent the residue of reaction between X and T, (c) the obtained first generation compound is activated by de-protecting it, (d) the activated compound is converted into alkali metal salt form by reaction with alkali metal hydroxide or zero valence alkali metal, and, if desired, (e) the alkali metal salt is reacted with further partially protected reagent T-U- V m to form the second generation protected dendrimer, (f) and steps (c) and (d) are repeated to provide higher generation dendrimer alkali metal salts.
