  • Publication number: 20230044967
    Abstract: An inkjet recording method contains the sequential steps of: applying an aqueous pre-coat composition to a substrate, or applying and drying the aqueous pre-coat composition to the substrate; and subsequently applying and drying an aqueous ink composition. The aqueous pre-coat composition contains at least an aggregating agent. The aqueous ink composition contains at least a pigment, a polymer dispersant, and resin fine particles. The aggregating agent is selected from a pyrolytic cation resin, an organic acid, or a multivalent metal salt. A neutralizer for the polymer dispersant is selected from an organic amine. In the step of drying the aqueous ink composition, a temperature at which the aqueous ink composition is dried is set to be equal to or higher than a pyrolytic temperature of the aggregating agent.

  • Patent number: 11247502
    Abstract: This inkjet image formation method has: a precoat liquid application step in which a precoat liquid is applied to a film substrate, the precoat liquid including a curing agent, a resin having a function group that reacts with the curing agent, and water; a precoat liquid drying step in which the precoat liquid applied to the film substrate is dried to form a precoat layer; an ink application step in which an ink is applied to the precoat layer by an inkjet method, the ink containing at least a coloring material, an organic solvent, and water; and an ink drying step in which the ink applied to the precoat layer is dried to form an image. The drying temperature T1, which is the highest temperature during the precoat liquid drying step, and the drying temperature T2, which is the highest temperature during the ink drying step, satisfy T2>T1.

  • Publication number: 20210329789
    Abstract: An object of the present invention is to provide a method for forming a conductive thin wire, the method being capable of improving thin wire formability, conductivity, adhesion, and transmittance of a conductive thin wire, a method for producing a transparent conductor, a method for producing a device, and a set of a conductive ink and a base material. This object is achieved by a method for forming a conductive thin wire on a base material by an inkjet method using a conductive ink containing at least a main solvent having a boiling point equal to or lower than the boiling point of water, a solvent having a boiling point higher than that of water, and a conductive material, in which the base material has surface energy of less than 40 mN/m, and conditions of 30°??1?70°, 0°??2?40°, and ?2??1 are satisfied when a forward contact angle of the conductive ink to the base material is represented by ?1, and a backward contact angle of the conductive ink to the base material is represented by ?2.
