  • Water based offset lithographic printing ink
    Patent number: 6444022
    Abstract: A water based offset lithographic ink comprising water; a modified rosin polymer comprised of resins soluble in water regardless of the pH of the water, resin rosin salts soluble in water at pH ranging from 7.5 to 10 and aqueous emulsion resins; a modified linseed oil; and pigment.
    Type: Grant
    Filed: May 20, 2000
    Date of Patent: September 3, 2002
    Assignee: Sun Chemical Corporation
    Inventors: Ramasamy Krishnan, Martin Thomas Czebotar, Hugo Babij
  • Water-based offset lithographic printing inks containing polymerizable surfactants
    Publication number: 20020083865
    Abstract: A water-based lithographic ink composition is described, and contains water, a resin-bonded pigment; a nonionic surfactant, a rewetting agent, and a polymerizable surfactant. The nonionic surfactant is present in an amount such that the dynamic surface tension of the total composition is about 20 to about 40 dynes/cm. The polymerizable surfactant is present in an amount of about 0.5% by weight to about 2% by weight of the composition. The ink composition may also contain other, conventional ink component, as desired.
