A waterbased heatset offset lithographic ink comprising water, polyamide resins or fumarated rosin resins, hydroxyethylethylene urea, a modified linseed oil, a dibutylated benzoguanamine, a pigment and p-toluene sulfonic acid.

Waterbased heatset offset ink compositions

A single fluid water-based offset lithographic news ink comprising water; a macromolecular resin binder comprised of a resin soluble in water regardless of the pH of the water, a rosin salt resin soluble in water at pH ranging from 7.5 to 10 and an aqueous emulsion polymer; pigment; a water dispersible soy bean based polymer; and a hydroxyethylehtylene urea re-wetting agent.

Water-based offset lithographic newspaper printing ink

A single fluid water-based gravure printing ink comprising water; a macromolecular resin binder comprised of resins soluble in water regardless of the pH of the water; resins water soluble at water pH value ranging from 7.5 to 10; and aqueous emulsion resins; pigment; and a hydroxyethyl ethylene urea re-wetting agent.

Water-based gravure printing ink

An offset lithographic printing process comprising printing at a relative humidity of 75-90% utilizing a water-based, single fluid, fountain solution free, printing ink containing (a) a macromolecular binder composed of binders soluble in water regardless of the pH of the water; resin rosin salt binders soluble in water at a pH from 7.5 to 10; and aqueous emulsion binders; (b) pigment and; (c) a re-wetting agent.

Offset lithographic printing process with a water based ink

A water-based offset lithographic printing ink comprising 10-70 wt. % macromolecular binders comprising macromolecular binders soluble in water regardless of the pH; macromolecular rosin salt binders soluble in water at a pH ranging from 7.5 to 10; and macromolecular binders comprised of aqueous emulsions; pigment; and a hydroxyethylethylene urea re-wetting agent.

Water-based offset lithographic printing ink

A process for improving the color value of a pigment and for imparting stability to a water-based printing ink containing such pigment which comprises adding a polyester or polyether to the strike tank during the pigment conditioning step; the preferred polyether is methyl hydroxypropyl cellulose and the preferred polyester is benzoic acid-modified trimellitic anhydride polyester.

Process for improving color value of a pigment

A printing ink useful for 'waterless' printing processes comprising a water-in-oil microemulsion wherein the water phase is present in an amount of about 5 to 20 wt. %, based on the weight of the ink. The water phase contains about 0.5 to 3 wt. %, based on the weight of the ink, of a surfactant which will not lower the surface tension (as measured at ambient temperature) of the ink, but will preferably increase the surface tension of the ink by at least about 5%. The ink optionally contains about 0.05 to 0.5 wt. %, based on the weight of the ink, of a water-soluble polymer capable of producing a viscosity in the water phase of about 5 to 10 poise as measured at ambient temperature.
