Abstract: A printing ink emulsion system containing an oil-base phase and water-miscible phase and exhibiting a high degree of stability against phase separation in use. The composition contains a small amount of phosphoric acid as a stabilizer, and is characterized in that the printing emulsion functions effectively as a single-application-step formulation in which the ink is retained only by the image portion of a plate, thus obviating the need for a separate operational step in which water is applied to a non-image area of a printing plate or roller to render that area ink-repellant.

Abstract: A fuel composition having enhanced tolerance for water comprises a hydrocarbon base fuel, a polyether more soluble in the hydrocarbon base fuel than in water, and, optionally, a supplemental fuel component such as, for example, an alcohol.

Abstract: An additive is provided which may be combined with printing inks to provide a printing ink composition which is retentive only by the image portion of a print plate. The additive includes a printing ink resin and a concentrated mineral acid. The additive may also include a polyhydric or monohydric alcohol or mixtures of such alcohols. A volatile solvent may also be present in the additive.
