Tall oil pitch may be reacted with a phenol-containing organic compound and formaldehyde or reactive equivalent thereof to prepare a resin. The reactants may further include polyhydric organic compound, &agr;,&bgr;-unsaturated carboxyl compound or ester thereof, and hydroxyl-containing non-phenolic organic compound. The resin may be formulated with a colorant to provide an ink for lithographic, gravure or letterpress printing.

Tall oil pitch-modified phenolic resin and methods related thereto

Distilled tall oil may be reacted with phenol-containing organic compound, formaldehyde or reactive equivalent thereof and hydroxyl-containing non-phenolic organic compound to prepare a resin. The resin may be formulated with a colorant to provide an ink for lithographic printing.

Modified phenolic resin and uses related thereto

A resinous binder is disclosed which is composed of a metal rosin resinate and a dilution increasing effective amount of polystyrene type resin having greater than 50,000 weight average molecular weight and an acid number less than 200. Also disclosed is a gravure printing ink which comprises a solvent, a colorant and a binder component wherein all or a portion of the binder component consists of the resinous binder of this invention. The use of the resinous binder of this invention in ink compositions results in significant dilution improvement without adversely affecting other desirable properties.

Resinous binders comprising a metal rosin resinate and a carboxylated

Stabilized, aqueous dispersions of multivalent metal humates are disclosed as a compatible and functional component in printing ink formulations.

Use of multivalent metal humates in printing inks

Aqueous ink compositions are disclosed which are an admixture a colorant, a resin binder which is the Diels-Alder adduct of maleic anhydride and 2,3- and 6,7-poly(alloocimene) or the partial-ester thereof and a solvating proportion of water. The inks are useful in flexographic and gravure printing.

Aqueous ink composition

Stabilized, aqueous dispersions of humate-surfactant are disclosed as inks.
