Abstract
The invention relates to a homogeneous liquid composition which comprises: (1) liquid hydrocarbon compatible with liquid toners for electrostatic imaging, (2) at least one charge director, and (3) at least one stabilizing component in an amount effective to stabilize the electrical properties of said at least one charge director, said component being selected from piperidinemethanol and polyoxyalkylene ethers of formula R(O--A).sub.n OH, wherein R is alkyl or alkenyl containing 10-20 carbon atoms, A is C.sub.2-3 -alkylene and n is 2-24; and to liquid toners characterized by the presence of at least one charge director and at least one stabilizing component therefor as defined in (3), above.
