  • Printing ink composition
    Patent number: 5372635
    Abstract: A printing ink composition comprising:(a) a dispersion of about 10-25 wt. %, based on the weight of the composition, of a pigment in about 40-90 wt. %, based on the weight of the composition, of a C.sub.7 -C.sub.40 oil; and(b) about 0.1 to 5.0 wt. %, based on the weight of the composition, of a soap of a tall oil fatty acid.The printing ink composition has the unique capability of being utilized in lithographic printing processes utilizing tap water rather than aqueous fountain solution in the dampening system of the press.

  • Process for the production of dispersions of polymers in non-aqueous vehicles
    Patent number: 4469826
    Abstract: Dispersions of polymer particles in non-aqueous vehicles are prepared by transferring the finely-divided polymer particles directly from an aqueous latex containing about 5 percent to 60 percent by weight of the polymer particles into the non-aqueous vehicle. The resulting dispersions can be used in the production of lithographic inks.
