    Abstract: The specification describes a process for making gelled ink resins which exhibit improved properties such as lower viscosity under low shear and less viscosity decrease with increasing shear. In a preferred embodiment, a rosin-based or hydrocarbon-based resin is mixed with an organic solvent and reacted with a polyamine reactant, such as melamine-formaldehyde resin or hexamethylene diamine, under conditions sufficient to produce a substantially covalently cross-link gelled resin. The resulting gelled resin resists viscosity breakdown under high shear conditions and may be used directly for making ink compositions, obviating the need for further gelation and avoiding the use of conventional organo-metallic gelling agents.

    Abstract: Oil-soluble, phenolic resin-modified natural resinic acid esters, which are able to form self-gelling mineral oil solutions and in the form of gel varnishes can advantageously be used as binder resins in printing inks for offset printing and letterpress printing, and also processes for their preparation from natural resins, phenols, aldehydes, condensation catalyst, esterifying agents and modifiers by reaction of the components at temperatures in the range from 80.degree. to 300.degree. C., individual components preferably being initially introduced and the other components being metered in, the combined use of a magnesium compound as condensation catalyst and the continuous removal of the water of reaction during the condensation reaction by azeotropic distillation with co-use of an inert organic solvent as distillative entraining agent being necessary and decisive for the self-gelling property of the process product.

  • Patent number: 5380789
    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.

  • Patent number: 5183847
    Abstract: Alkali-soluble resins, their preparation and use are disclosed herein. The resins are carboxylated polyamide/acrylic resins and are synthesized in a two-step fusion process in which a polyamide is first condensed with a carboxylated rosin and this intermediate product is then further condensed with an acrylic or styrene/acrylic copolymer.

  • Patent number: 4710228
    Abstract: Disclosed are edible film coating compositions of low moisture permeability and their methods of preparation. The compositions comprise cross-linked, refined shellac and preferably an edible member having a reactive hydroxyl or acid moiety selected from the group consisting of edible sources of polyphenolics, edible sources of benzaldehyde and derivatives, acetylated monoglycerides, polyglycerol esters, edible straight chain mono-carboxylic acid, edible di-carboxylic acids and mixtures thereof. Useful weight ratios of shellac to reactant range from 1:0.001 to 0.1. In the preferred method of preparation, the shellac is cross-linked with the reactants in a dry, molten mixture by heating at 130.degree. to 175.degree. C. for 2 to 15 minutes. The resulting coating compound while molten is dissolved in a food grade solvent, applied to a substrate and dried.

  • Patent number: 4552592
    Abstract: Process for preparing printing ink binders based on reaction products of (a) natural resins, (b) other synthetic resins, (c) .alpha.,.beta.-olefinically unsaturated carboxylic acid units and (d) calcium compounds and, if appropriate, other compounds of metals of group II of the periodic system.The compounds (a) to (c) are reacted to give a product having an acid number of 75 to 150, which is then reacted with metal compounds in such a way that the acid number is reduced by at least one third. Unreacted metal compounds present in the resulting reaction product are then converted by means of acetic acid, via acetates, into salts of the resins. The resulting binders are used for preparing printing inks.
