Natural oil derived gelled ink vehicles
Novel natural oil derived ink vehicles are provided by a two step process that does not require the addition of gelants or the irreversible heat bodying or polymerization of the oil. The gelled natural oil may be used as the vehicle/carrier in the ink formulation or alternatively used as a carrier or dispersant for additives in ink formulations. The gelled ink vehicles disclosed have many advantages over ink vehicles disclosed in the prior art.
1. A gelled printing vehicle for heatset or other lithographic printing comprising an adduct derived from the reaction product of a natural unsaturated triglyceride oil, or derivative with a substrate suitable for Diels Alder reaction or Ene reaction; said adduct being reacted in a non-aqueous neutralization/esterification reaction with an alkanolamine to form an ionomeric anhydrous gel.
2. The gelled printing vehicles of claim 1 , useful as carriers or vehicles for additives in non-aqueous ink formulations.
3. The gelled printing vehicles of claim 1 , useful as dispersants for additives in non-aqueous formulations.
4. A gelled printing vehicle for heatset or other lithographic printing comprising an adduct derived from the reaction product of a natural unsaturated triglyceride oil, or derivative with a substrate suitable for Diels Alder reaction or Ene reaction said adduct being reacted with an alkanolamine to form an ionomeric anhydrous gel.
5. The gelled printing vehicles of claim 4 , useful as carriers or vehicles for additives in non-aqueous ink formulations.
6. The gelled printing vehicles of claim 4 , useful as dispersants for additives in non-aqueous formulations.
7. A gelled printing vehicle for heatset or other lithographic printing comprising an ionomeric anhydrous gel adduct derived from the reaction of an alkanolamine with a reaction product of a natural unsaturated triglyceride oil, or derivative with a substrate suitable for Diels Alder reaction or Ene reaction.
8. The gelled printing vehicle for heatset or other lithographic printing of claim 7 wherein said reaction with said alkanolamine is a non-aqueous neutralization/esterification reaction.
