Abstract
Abstract A heterologous ink composition for use in an ink jet apparatus features two miscibly incompatible components made compatible by the use of a common solvent having miscibility for both aqueously and non-aqueously miscible components. The heterologous ink composition derives its print quality characteristic from the non-aqueously miscible component and its good jetability and small dot size from its aqueously miscible component.
