Patent ID: 8252105

Claim:
A composition useful as an additive for non-aqueous inks that provides rub-off and transfer resistance to printed paper stock consisting essentially of: (a) about 20% by weight to about 99.5% of a base material having a viscosity of at least about 50,000 centipoise at about 72° Fahrenheit formed from one or more saturated or unsaturated straight or branched triglyceride esters derived from fatty acids selected from the groups of C 8 to C 24 fatty acids or mixtures thereof, said triglycerides being partially to fully hydrogenated; and (b) about 0.5 to about 80 percent by weight of a finely divided material selected from a group consisting of fluorinated polymers, natural and synthetic waxes and hydrogenated triglycerides derived from C 8 to C 24 unsaturated fatty acids wherein said material has particles having a size of less than about 10 microns and wherein said composition provides an ink having minimal loss in color density when compared with an ink that doesn't have the additive.
