ABSTRACT:
The invention provides novel colored toner and developer compositions containing polymeric colorants. Such compositions may contain poly(oxyalkylene) or poly(alkylester) substituted color chromophores which are attached to relatively long chained ologomers. The color toner and developer compositions of the invention resist color bleeding and aggregation, and may retain their color fidelity over extended time periods. Such color toner compositions are useful in color imaging systems. The invention provides novel compositions that can readily be formulated and manufactured using the polymeric or oligomeric colorants. The toners of the invention may contain charge control agents, thermoplastic resins, colorants, and additives.
