Process for the Preparation of Aqueous Dispersions of Particles of Water-Soluble Polymers and the Particles Obtained (Technology #: 050100-01)

The invention is a process for the preparation of crosslinked water-swellable polymer particles. First, an aqueous polymer solution containing a water-soluble polymer having at least one functional group or charge, is combined with aqueous medium. The aqueous polymer solution is then mixed under moderate agitation with an oil medium and an emulsifier...

Printing Ink Compositions, Methods For Making Same And Uses Thereof (Technology #: 080597-01)

Aqueous based printing ink compositions adapted for use in gravure and flexographic printing on hydrophobic substrates are prepared by combining a low-viscosity resin emulsion having an average particle diameter of less than about 0.5 microns and comprised of hydrophobic, moisture resistant, adherent resin forming components with a pigment paste...

Aqueous Coating Compositions, Methods for Making Same and Uses Thereof - "Water Based Ink" (Technology #: 101698-01)

An aqueous unpigmented coating and printing composition useful for gravure and flexographic printing on plastic and metal substrates is provided by preparing an aqueous emulsion of a hydrophobic UV curable oligomer and a photoinitiator and adding about 1 to 10% by weight of the composition of a water soluble or reducible polymeric thickener in an...
