Latest Patents
One of his latest patents is for a non-aqueous pigment ink. This ink includes pigment, a non-aqueous solvent, and a non-aqueous resin that functions to disperse the pigment dissolved in the non-aqueous solvent. The non-aqueous solvent comprises a hydrocarbon-based non-polar solvent at 50% by mass or more with respect to the total amount of solvent. The non-aqueous resin is an acrylic polymer with a comb-shaped structure, where alkyl groups with carbon numbers from 8 to 18 and urethane groups form side chains on a (meth)acrylate main chain. This acrylic polymer is a copolymer of an alkyl(meth)acrylate having alkyl groups with a carbon number from 8 to 18, a reactive (meth)acrylate with functional groups that react with amino groups, and a monomer having β-diketone groups or β-keto acid ester groups. The urethane groups are introduced through reactions between the functional groups that react with amino groups, amino alcohol, and a multivalent isocyanate compound. The mass ratio between the copolymer moiety and the urethane group moiety in the acrylic polymer ranges from 80:20 to 99:1.
Another significant patent by Kon is for a non-aqueous inkjet ink that comprises silica and Brilliant Carmine 6B. The peak area obtained during the measurement of the organic acid quantity of a water extract of Brilliant Carmine 6B, using a capillary electrophoresis apparatus, is selected within the range of 50 to 300 mABU*sec.
