  • Vegetable oil-based printing ink
    Patent number: 5122188
    Abstract: Printing inks, which do not require any petroleum-derived component, are prepared from vegetable oils by heat bodying the oils to within a specified viscosity range. The process is easily tailored to give products having viscosity, tackiness, ruboff resistance, and color density properties which meet or exceed industry standards. The inherent light coloration of the vehicles permits formulation into colored inks having substantially reduced pigment levels.
