Abstract
Abstract A modified hydrocarbon resin comprising (A) a major amount of a cycloaliphatic diene resin component and (B) a minor amount of an olefinically unsaturated polycarboxylic acid component, wherein at least 5% of the carboxyl groups are esterified with an alcohol selected from the group consisting of (a) a monohydric, (b) a dihydric alcohol and (c) a combination of (a) and (b), a process for its preparation and a printing ink composition containing said modified hydrocarbon resin.

Claims Analysis
Total Claims: 14
Claim 1
Independent Claim
113 words
A printing ink composition which comprises as a binder a modified hydrocarbon resin being a reaction product of (A) a major amount of a cycloaliphatic diene resin component said cycloaliphatic resin having been derived from polymerizable hydrocarbon monomers containing more than 50% by weight of cycloaliphatic diene monomers and (B) 1 up to 50% by weight of an olefinically unsaturated polycarboxylic acid component, wherein at least 5% of the carboxyl groups are esterified with an alcohol selected from the group consisting of (a) a polyhydric alcohol and (b) a combination of the specified minimum amount of a polyhydric alcohol and an additional amount of a monohydric alcohol, a pigment, and a non-aqueous medium.
Claim 2
Dependent Claim
