Abstract
A chemically prepared core shell toner formulation for use in electrophotography having an inventive softening agent consisting of a core shell latex having an encapsulated interpenetrating polymer network microgel in the core of the toner is disclosed. Having this core shell latex with an encapsulated IPN microgel in the core of the toner results in a toner that can simultaneously fuse at a desirable low temperature and survive the temperature extremes associated with shipping and storage.
