Abstract: A flushing vehicle for lithographic inks is the reaction product of a tall oil rosin-modified maleic ester resin with an acid number of less than about 30, and about 2-16 wt. %, based on the weight of the ester, of a polyamide resin with an amine number less than about 110. The flushing vehicle is prepared by heating a reaction mixture containing the rosin-modified ester and the polyamide resin to a temperature of about 190.degree.-280.degree. C.; and holding at a temperature of 190.degree.-280.degree. C. until the viscosity of the reaction mixture becomes constant.

Abstract: A rosin modified acrylic resin for use in a toner composition is provided. The resin is prepared by steam stripping a mixture of solution polymerized styrene-acrylic copolymer rosin, and a suitable solvent, such as toluene or xylene, followed by cooling and grinding to form the styrene acrylic-rosin resin. This binder resin can be used in a toner composition which, due to the resin, has an inherent positive charge of at least 2.0.

Abstract: A novel complexer for use in aqueous coating compositions formed from acidic resins, as well as the coating compositions, are described. The complexer is formed from a metal having a coordination value in excess of its valence and a polyalkylene polyamine along with, optionally, organic acids and cometals. The acidic resin, partially neutralized with ammonia, is added to the formed complexer to form the coating composition, a coordinate, which, upon drying, provides films which are water resistant and have excellent wet rub resistance. The coating compositions are particularly useful for inks, including gravure and flexographic inks.
