Latest Patents

One of her latest patents describes a recording method that involves a two-step coating process. The first step includes applying a treatment liquid A to a recording medium, followed by a second coating of treatment liquid B. After these coatings, an ink composition containing a coloring material is discharged from a nozzle onto the recording medium. Treatment liquid A adjusts the wettability of treatment liquid B and contains either a resin or inorganic oxide fine particles. Treatment liquid B is designed to thicken or insolubilize the ink composition and includes a polyvalent metal salt, an organic acid, or an organic acid salt.

Another notable patent involves a treatment liquid used in inkjet recording on non-absorbent media. This treatment liquid contains water, a coagulant, and two or more types of organic solvents. The organic compounds in the treatment liquid do not include the coagulant, surfactant, or resin. The formulation is carefully calculated to ensure that the product of the log P value and the content of each organic compound is equal to or less than -10.
