Claims
- 1. 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.
- 2. A composition as claimed in claim 1 wherein the diene resin component is derived from a hydrocarbon fraction with a boiling range of 20.degree. to 180.degree. C.
- 3. A composition as claimed in claim 1 wherein the diene resin component has a melting point of at least 40.degree. C and a bromine number of at least 30.
- 4. A composition as claimed in claim 1 wherein the polycarboxylic acid component is an .alpha.,.beta.-unsaturated polycarboxylic acid having from 4 to 8 carbon atoms or a functional thereof.
- 5. A composition as claimed in claim 1 wherein the polycarboxylic acid component contains carboxyl groups esterified with an alcohol containing up to 20 carbon atoms.
- 6. A composition as claimed in claim 1 which additionally contains an olefinically unsaturated monocarboxylic acid component selected from the group consisting of a monocarboxylic acid containing from 3 to 12 carbon atoms and a functional derivative thereof which monocarboxylic acid component is present in an amount up to 200% by weight of the polycarboxylic acid component.
- 7. A composition as claimed in claim 1 wherein the diene resin component is an aliphatic diene resin modified by at least one other natural or synthetic resin selected from the group consisting of a hydrocarbon resin, an acid - modified hydrocarbon resin and colophony.
- 8. A composition as claimed in claim 1 which additionally contains a mono - or polyhydric free phenol in an amount up to 5% by weight of the diene resin component.
- 9. A composition as claimed in claim 1 wherein from 0.1 to 10% of the unesterified carboxyl groups are present in salt form with a metal of groups I to III of the Periodic Table.
- 10. A composition as claimed in claim 1 wherein the diene resin component (A) the diene resin component has a melting point of at least 40.degree. C and a bromine number of at least 30 and is derived from a hydrocarbon fraction with a boiling range of 20 to 180.degree. C and the polycarboxylic acid component (B) is an .alpha.,.beta.-unsaturated polycarboxylic acid having from 4 to 8 carbon atoms or a functional derivative thereof the carboxyl groups thereof are esterified with an alcohol containing up to 20 carbon atoms.
- 11. The printing ink composition of claim 1 in which said diene resin component is derived by thermal polymerization at temperatures between 200.degree. and 300.degree. C.
- 12. The printing ink composition of claim 1 in which the alcohol reactant is selected from the group consisting of an at least dihydric and an at most trihydric alcohol.
- 13. The printing ink composition of claim 12 in which the diene resin component is derived by thermal polymerization at temperatures between 200.degree. and 300.degree. C.
