| titleOfInvention | Gravure ink for paper |
| abstract | A gravure ink for paper comprises a pigment dispersed in an organic solvent solution of a petroleum resin which has been prepared by a Friedel-Crafts polymerization of a steam cracked petroleum strearys boiling between -20 DEG and 280 DEG C. and which has been reacted in the molten state with an a ,b -unsaturated dicarboxylic acid or anhydride and then reacted with an oxide, halide or hydroxide of a metal of Group II of the Mendeleef Periodic Table so as to form a salt. The petroleum resin may be derived from an ethylenically unsaturated hydrocarbon using as catalyst a phenolate of boron fluoride and may have a bromine value of 5-80 and a Ball and Ring softening point of 50-130 DEG C. The a ,b -unsaturated compound may be maleic or citraconic acid or anhydride, or fumaric or itaconic acid, and its reaction with the petroleum resin may be carried out in the presence of gum or tall-oil rosin or a phenol/ formaldehyde pre-condensate and ditert butyl peroxide. The Group II metal compound may be calcium hydroxide or zinc oxide and its reaction with the resin adduct may be carried out in the presence of calcium acetate and also an aliphatic polyhydric alcohol, e.g. glycerol, so as to both esterify and form a salt with the carboxyl group of the resin adduct. The ink may comprise a toluene solution of the treated resin (of viscosity 30-150 cps. at 25 DEG C.) containing 3-40% of a pigment, e.g. Carmine 6B(C.I. No. 15850). |
