Abstract
A process for the preparation of a modified hydrocarbon resin suitable for use as a binder in a printing ink from a hydrocarbon resin (I) relatively unsuitable for use as a binder in a printing ink and having a melting point of at most 110.degree. C. which comprises reacting in at least one step in any desired sequence a reactant selected from the group consisting of PA0 (I) at least one hydrocarbon resin based on at least one polymerizable hydrocarbon monomer selected from the group consisting of PA1 (a) 20 to 100% by weight, referred to the total of polymerizable monomers, of hydrocarbon fractions containing substantial and essential amounts of C.sub.5 -fractions, PA1 (b) 15 to 50% by weight, referred to the total of polymerizable monomers, of methylcyclopentadiene, PA0 (Ia) a combination of (I) with an olefinically unsaturated monomer hydrocarbon selected from the group consisting of aromatic hydrocarbons of 8 to 12 carbon atoms, cycloaliphatic hydrocarbons having 5 to 10 carbon atoms and aliphatic hydrocarbons having 2 to 12 carbon atoms, the total amount of monomers always being 100% by weight, with PA0 (II) 3 to 20% as much by weight of a dicarboxylic acid unit selected from …
