Abstract
Abstract This invention provides vehicles for printing ink containing a resinous ingredient prepared by allowing a petroleum resin to undergo an addition reaction with an unsaturated polybasic acid or anhydride thereof and allowing the addition product to react with a polyalkylene polyamine that contains an alkyl group having from eight to 30 carbon atoms in the molecule to permit quick setting, produce good gloss and provide good stability on printing presses.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
105 words
A VEHICLE FOR A PRINTING INK WHICH COMPRISES A RESINOUS INGREDIENT PREPARED BY ALLOWING A PETROLEUM RESIN HAVING A SOFTENING POINT BETWEEN 80* TO 180*C TO UNDERGO AN ADDITION REACTION WITH AN UNSATURATED DIBASIC ACID OR ANHYDRIDE THEREOF AND THEN ALLOWING THE ADDITION PRODUCT TO REACT WITH A POLYALKYLENE POLYAMINE IN WHICH TWO OR THREE AMINO GROUPS ARE BONDED TO DIFFERENT CARBONS OF MORE THAN TWO ALKYL GROUPS OF METHYLENE, ETHYLENE, PROPYLENE, OR BUTYLENE, TWO OF THE AMINE GROUPS BEING LOCATED AT BOTH TERMINALS OF THE MOLECULE, THE AMOUNT OF SAID POLYALKYLENE POLYAMINE BEING FROM 0.1 TO 3 MOLES PER MOL OF UNSATURATED DIBASIC ACID.
Claim 2
Dependent Claim
105 words
A VEHICLE FOR A PRINTING INK WHICH COMPRISES A RESINOUS INGREDIENT PREPARED BY ALLOWING A PETROLEUM RESIN HAVING A SOFTENING POINT BETWEEN 80* TO 180*C TO UNDERGO AN ADDITION REACTION WITH AN UNSATURATED DIBASIC ACID OR ANHYDRIDE THEREOF AND THEN ALLOWING THE ADDITION PRODUCT TO REACT WITH A POLYALKYLENE POLYAMINE IN WHICH TWO OR THREE AMINO GROUPS ARE BONDED TO DIFFERENT CARBONS OF MORE THAN TWO ALKYL GROUPS OF METHYLENE, ETHYLENE, PROPYLENE, OR BUTYLENE, TWO OF THE AMINE GROUPS BEING LOCATED AT BOTH TERMINALS OF THE MOLECULE, THE AMOUNT OF SAID POLYALKYLENE POLYAMINE BEING FROM 0.1 TO 3 MOLES PER MOL OF UNSATURATED DIBASIC ACID.
Claim 3
Dependent Claim
67 words
Vehicles for printing ink according to claim 1 wherein said petroleum resin is a resinous substance of thermoplastic reactivity in which said resinous substance is prepared by polymerizing a cracked fraction containing an unsaturated hydrocarbon with a boiling point in the range from 30* * 280*C separated out of the petroleum distillates formed by pyrolysis or catalytic cracking in the presence of a catalyst of Friedel-Craft type.
Claim 4
Dependent Claim
28 words
Vehicles for printing ink according to claim 1 wherein said unsaturated polybasic acids or anhydrides thereof is maleic acid, fumaric acid, citraconic acid, tetrahydrophthalic acid or their anhydrides.
Claim 5
Dependent Claim
22 words
Vehicles for printing ink according to claim 1 wherein said polyamine is oleyl trimethylene diamine, trimethylene diamine monorosinate or diethylene triamine monooleate.
