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 and in any desired sequence (I) as defined below with (II) approximately 3-20% as much by weight of a dicarboxylic acid unit as defined below and with (III) approximately 1-100% as much by weight of an alkyl phenol-aldehyde resin or its equivalent as defined below
wherein
(I) is a hydrocarbon resin containing at most 20% by weight of indene or methyl indene units and is based on a considerable proportion of polymerizable hydrocarbon monomers containing about 5 to 11 carbon atoms and at most 20% by weight of indene or methyl indene
(II) is selected from the group consisting of
