2-(1,2-benzisothiazol-3(2H)-ylidene 1,1-dioxide)acetamides negative charge control agents for electrostatographic toners and developers

摘要

The invention, in its broader aspects provides an electrophotographic toner having polymeric binder and 2-(1,2-benzisothiazol-3(2H)-ylidene 1,1-dioxide)acetamides as charge control agent.wherein n is 1 or 2; R and R1 are defined in the specification. The compounds are useful as charge-control agents in electrostatographic toners and developers.
