Claim 1
Independent Claim
199 words
A process for the preparation of a modified hydrocarbon resin suitable for use as a binder in a printing ink from a hydrocarbon resin (1) relatively unsuitable for use as a binder in the printing ink and having a melting point of at most 110° C. which comprises reacting in a multiplicity of steps at first a starting reactant (I) at least one hydrocarbon resin containing indene or methylindene units hydrocarbon fractions containing olefinically unsaturated monomers with on average 9 carbon atoms, and (Ia) a combination of (I) with an olefinically unsaturated monomer hydrocarbon selected from the group consisting of aromatic hydrocarbons of 6 to 12 carbon atoms, with (II) 3 to 20% as much as weight of a dicarboxylic acid unit selected from the group consisting of (IIa) an α,β-olefinically unsaturated dicarboxylic acid and (IIb) an equivalent amount of the corresponding dicarboxylic anhydride or ester of the dicarboxylic acid as defined in (IIa) and subsequently with 1 to 100% as much by weight of an alkylphenol-aldehyde resin component III; the proportion of (I), (II) and (III) being correlated so that said modified hydrocarbon resin has a melting point of at least 120° C. of at least 100 centipoise.

Dependent Claim
