ABSTRACT:
Magnetic carrier core particles are provided which are coated with a Werner complex. The coating is readily accomplished by dispersing magnetic core particles in a solution of the Werner type complex. A hydroxyl group containing polymer can also be present which functions to enhance coating thickness. The Werner complexes are highly reactive, bond strongly to hydroxyl groups, and absorb readily into the core particles. Coated particles display excellent useful life capability and developer compositions containing such coated cores produce high resolution developed images.
