Abstract: A coating formulation is disclosed that is capable of imparting, onto the treated substrate, an excellent adsorption performance, good print appearance, and enhanced rub-off resistance. Furthermore, the disclosed formulation has good ink stability and offers high quality print appearance throughout long printing runs of high speeding printing applications. The formulation comprises an activated carbon having a particle size of less than 1 micron and a binder, wherein an amount of the binder by weight is in a range of about 30 parts to 100 parts per 100 parts of the activated carbon, and the formulation has a dry basis BET Surface Area of greater than 100 m2/g.

Abstract: The present invention relates to surface sizing compositions, methods for making such compositions, processes for sizing paper products using such compositions, and paper products which have been sized with such compositions. In particular, the invention relates to novel surface sizing compositions comprising rosin-based component and styrene-carboxylic copolymer.

Abstract: A rosin fatty acid vinylic emulsion composition produced by (A) polymerizing a mixture of vinylic monomers in the presence of a fatty acid rosin mixture comprising a mixture of fatty acids and rosin, at temperature in the range of about 135° C. to about 175° C., to produce a rosin-fatty acid vinylic polymer having a weight average molecular weight in the range of 4,000 to about 12,000; and (B) subsequently emulsion polymerizing another mixture of vinylic monomers in the presence of the rosin-fatty acid vinylic polymer of step A at temperature in the range of about 20° C. to about 100° C., to produce a rosin-fatty acid vinylic emulsion composition with polymers having a weight average molecular weight in the range of about 40,000 to about 200,000.

Abstract: Novel polymeric compounds are disclosed which may be utilized alone, or after being further polymerized into an emulsion polymer, to form pigmented compositions that are useful in a variety of pigmented compositions, including inks. The inks produced have high bond strength, and are suitable for use in a large number of printing processes, most notably processes involving printing onto flexible substrates.
