Abstract
Disclosed are inks containing compounds of the formula: ##STR1## where --R.sup.1 is --H or --CH.sub.3 PA1 --R.sup.2 is an aliphatic, preferably linear hydrocarbyl, radical having 11-23 carbon atoms and containing at least one olefinic double bond, or mixtures thereof, --R.sup.2 being free of terminal double bonds, and PA1 --X-- is either (a) --OR.sup.3 O-- in which R.sup.3 is an aliphatic or cycloaliphatic hydrocarbon residue containing from 2 to 10 carbon atoms, or (b) --O(CH.sub.2 CHR.sup.4 O).sub.n -- where R.sup.4 is --H or --CH.sub.3 and n is an integer of from 2-10, or mixtures thereof. Preferably, --X-- is --OR.sup.3 O-- wherein R.sup.3 is --CH.sub.2 CH.sub.2 -- or ##STR2## --R.sup.1 is --CH.sub.3, and --R.sup.2 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 …
