    Abstract: Process for preparing printing ink binders based on reaction products of (a) natural resins, a copolymer (b+c) of (b) polymerizable hydrocarbons having isolated C5 rings and (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.

    Abstract: A process for the preparation of partial esters and partial salts with divalent metal compounds of reaction products of natural resinic acids and unsaturated dicarboxylic acids which typically comprises the following steps: (a) reacting a natural resinic acid with an olefinically unsaturated dicarboxylic acid; (b) partially neutralizing the product of step (a) with a calcium compound; (c) partially esterifying the product of step (b) with a polyhydric alcohol; (d) reacting the product of step (c) with a resol or a mixture of resols; and (e) continuing the reaction of step (d) to complete partial salt formation and partial esterification. The product is useful for printing inks.

    Abstract: 1485444 Pigment composition HOECHST AG 30 Oct 1974 [30 Oct 1973] 46954/74 Headings C3R and C3P A pigment composition in powder or paste form comprises a pigment and a binding agent comprising a mixture of (a) an alkyd resin having an oil content of 70-80% by weight derived from isophthalic acid, phthalic acid, an α,#- unsaturated dicarboxylic acid, glycerol and pentaerythritol, (b) a hydrocarbon resin having an average molecular weight of 600 to 1700 and a bromine number of from 10 to 200, and (c) a mineral oil boiling between 240‹ and 320‹ C., the ratio of (a) to (b) being from 1 : 1 to 1 : 1À5 and that of (a) + (b) to (c) being from 4 : 1 to 0À7 : 1. The composition may contain from 5 to 75% by weight of the binding agent. The composition may also include a surfactant.
