Latest Patents

Kamada holds a patent for a "Sheet surface treating agent and ink-jet printing paper." This invention involves a treating agent for a sheet surface that comprises a graft copolymer made up of a backbone polymer and a branch polymer. One of these polymers contains vinyl alcohol units, while the other has cationic groups. The treating agent is applied to a pulp sheet or plastic sheet, which is then used in ink-jet printing. The introduction of cationic groups is achieved through graft copolymerization using di(meth)allylamine-based and/or (meth)acryl-based monomers. Alternatively, the graft copolymer can be obtained by grafting N-vinylcarboxylic acid amide monomer followed by hydrolysis. A preferred formula weight ratio of vinyl alcohol units to introduced cationic groups is between 1:20 to 2:1 for balanced performance.
