Abstract
Abstract A process of producing an ink by A. providing an emulsion which comprises: 1. an organic liquid selected from the group consisting of: oleophilic resins organic solvents and mixtures thereof, 2. an emulsification agent and 3. water B. forming an aqueous suspension of a pigment, C. admixing the emulsion with the pigment suspension, D. concentrating the emulsion and pigment suspension mixture and E. preparing an ink directly from the concentrated emulsion-pigment mixture.
