Abstract

Abstract Disclosed are inks containing compounds of the formula: <IMAGE> where -R1 is -H or -CH3 -R2 is an aliphatic, preferably linear hydrocarbyl, radical having 11-23 carbon atoms and containing at least one olefinic double bond, or mixtures thereof, -R2 being free of terminal double bonds, and -X- is either (a) -OR3O- in which R3 is an aliphatic or cycloaliphatic hydrocarbon residue containing from 2 to 10 carbon atoms, or (b) -O(CH2CHR4O)n- where R4 is -H or -CH3 and n is an integer of from 2-10, or mixtures thereof. Preferably, -X- is -OR3O- wherein R3 is -CH2CH2- or <IMAGE> -R1 is -CH3, and -R2 is a mixture of hydrocarbyl moieties derived from drying oils and is at least in part polyunsaturated, and more preferably, predominantly so. The products are oxidatively curable reactive diluents of exceptionally low viscosity and low volatility which are useful for the preparation of high solids lithographic inks to reduce atmospheric pollution caused by volatile non-reactive solvents. In addition to compounds of the given formula, other esters of drying oil fatty acids with various addition-polymerizable olefinically unsaturated hydroxyl-containing compounds are disclosed. Another way of describing the preferred reactive diluents of the invention is to define them as the mixed esters of a polyol with (1) mixed natural drying oil fatty acids and (2) an alpha , beta -ethylenically unsaturated acid.
