  • Patent number: 10487455
    Abstract: An ink application method is provided. In the method, an ink is discharged to an object by an inkjet method, to apply the ink to the object. The object includes a base material and a gel layer overlying the base material, and the gel layer includes a vinyl chloride resin and a plasticizer. The ink is an oil-based ink. When a free induction decay curve of the object obtained by a pulse NMR method is separated into two curves respectively derived from a hard component and a soft component, the curve derived from the hard component accounts for 35% to 40% of the free induction decay curve, and the curve derived from the soft component has a spin-spin relaxation time of from 30.0 to 45.0 ms when obtained by a Hahn echo method.
