Abstract: Rosin modified phenolic resins are prepared by reacting together resin acid, fatty acid, tri- or higher-functional phenolic compound and aldehyde. The fatty acid may be Monomer (derived from the fatty acid dimerization process). The reaction mixture may optionally include a,I3-olefinically unsaturated carbonyl compounds and/or polyol. The resin may be dissolved in a solvent to form a varnish. The resin may be used as a component of printing inks, e.g., inks for lithographic or gravure printing.

Abstract: A resin varnish for printing ink is produced by condensing phenol and formaldehyde in an ink solvent to obtain an ink solvent solution of resole initial condensate, after which the resole initial condensate and a rosin ester containing 30-60 wt % non-aromatic conjugate resin acid and 20-60 wt % aromatic resin acid are reacted at 100-250° C. in a system containing ink solvent or in a system containing ink solvent and drying oil. A high-viscosity, high-molecular-weight ink resin is produced efficiently by reacting, with resole initial condensate in ink solvent, a rosin ester containing specified contents by percentage of conjugate acid and aromatic resin acid. The resin varnish obtained has very few decomposition components and nonuniformly gelled components, so it also is suitable for screen printing ink and letterpress printing ink, in addition to offset printing ink.

Abstract: Process for esterifying a polyphenolic oligomer extract of plant origin by the action of an acid chloride, the compositions obtained by this process and their use in human therapy or in cosmetics are described. The extract is placed in a liquid medium which is not a solvent for the extract but which is a solvent for the ester(s) to be obtained, so as to obtain a suspension. At least one aliphatic tertiary amine of low boiling point is added to the suspension in the presence of a catalytic amount of at least one organic base other than pyridine. At least one fatty acid chloride is introduced into this mixture, the reaction mixture being stirred at a temperature below 40.degree. C. and then concentrated by evaporation in order to obtain an esterified extract.

Abstract: A catalyst selected from a perfluorosulfonic acid and an anhydride thereof enables a non-conjugated drying oil to react with a phenol to form a phenol-added vegetable oil without causing hydrolysis of the non-conjugated drying oil. The phenol-added vegetable oil is allowed to react with an aldehyde to form a vegetable oil-modified phenolic resin. A laminate produced by impregnating paper with the vegetable oil-modified phenolic resin and laminating and molding the impregnated paper is excellent in low temperature punching quality and electrical properties and is free from low molecular weight components oozing out the surface of the laminate.
