Abstract: The addition of an organophosphato-titanate and an organophosphato-zirconate to printing ink improves the adhesivity of the ink to a variety of substrates. A concentrate of the two organo-metallic components may be added to a conventional ink or added to the ink formulation during the ink's initial preparation. In addition to improving adhesivity, the additives reduce drying time, permit more rapid processing, and minimize the need for solvent diluents.

Abstract: The present invention provides a process for the production of a metallized azo pigment having the formula ##STR1## in which R and R.sub.1, independently, are hydrogen, halogen or alkyl; X.sub.1 is SO.sub.3.sup..crclbar. or CO.sub.2.sup..crclbar. ; and M is Ca, Sr, Mn or Ba; comprising coupling, at a pH value below 7.0, a diazotized amine of formula ##STR2## in which R, R.sub.1 and X.sub.1 have their previous significance, with a coupling component of formula ##STR3## to produce an azo dyestuff having the formula ##STR4## in which R, R.sub.1 and X.sub.1 have their previous significance, and Y is an alkaline earth metal or ammonium ion; and laking the dyestuff of formula IV during or after its production with one or more salts of a metal M wherein M has its previous significance.Also disclosed is a new modification of a pigment of formula I.

Abstract: Inks, particularly inks for ink jet printing, contain at least one compound of the formula I ##STR1## as a stabilizer. The symbols R.sub.1, R.sub.2, R.sub.3, R.sub.4, R.sub.3 ' and R.sub.4 ' are as defined in claim 1. The compounds are in part novel and are suitable for use as light stabilizers for organic materials.

Abstract: A gravure printing ink comprising, a vehicle having a binder dissolved in a hydrocarbon solvent and a pigment dispersed therein, wherein the binder is a modified rosin resinate prepared by reacting a rosin modified by reaction with a dienophile to form a rosin adduct, and reacting the rosin adduct with from about 0.1% to about 5.0% by weight of the resinate of a reactive compound of a metal belonging to Group I of the Periodic Table to form a resinate.
