Abstract: An information processing device includes an associator, an extractor, and an outputter. The associator is configured to associate each of a series of pieces of history data related to at least any of deposits and withdrawals of a user with any of a plurality of behaviors related to an economic activity of the user. The extractor is configured to extract an inducement destination candidate according to behavioral characteristics of the user based on changes along a time series of each of the plurality of behaviors. The outputter is configured to output information indicating the extracted inducement destination candidate to a predetermined output destination.

Abstract: Provided is an aqueous ink that is suppressed from causing mist and is excellent in storage stability. The aqueous ink is an aqueous ink to be ejected from a recording head of an ink jet system through an action of thermal energy. The aqueous ink includes a first surfactant and a second surfactant. The first surfactant contains a compound represented by the following general formula (1) (in the general formula (1), “m” and “n” each independently represent an integer of 1 or more and satisfy a relationship of m+n?10, and “a” represents an integer of 10 or more to 20 or less). The second surfactant contains an acetylene glycol compound.

Abstract: Provided is an aqueous ink for ink jet including: pigments; a urethane resin; and a silicone-based surfactant. The pigments include a first pigment and a second pigment, the first pigment is a naphthol AS-based azo pigment and the second pigment is a quinacridone-based pigment. The urethane resin is a water-soluble urethane resin having a unit derived from a polyisocyanate, a unit derived from a polyol having no acid group and a unit derived from a polyol having an acid group. The silicone-based surfactant is at least one kind selected from the group consisting of compounds represented by the following respective general formulae (1) to (3), has a weight-average molecular weight of 800 or more to 10,000 or less and has an HLB value measured by Griffin's method of 4 or more.

Abstract: Provided is an ink jet recording method including using an ink jet recording apparatus, the ink jet recording apparatus including: an aqueous ink containing resin particles each dyed with a fluorescent dye. A plurality of nozzle arrays include a first nozzle array and a second nozzle array arranged in a predetermined direction so as to be displaced from each other in such a manner that end nozzles in the nozzle arrays adjacent to each other form an overlapping portion in a direction intersecting the predetermined direction. The aqueous ink is ejected from overlapping nozzles at the overlapping portion while the nozzles are allocated to the first nozzle array and the second nozzle array. An application time difference of the aqueous ink ejected from the overlapping nozzles is 20 milliseconds or less.

Abstract: Provided is an ink jet recording method including recording an image on a recording medium through use of an ink jet recording apparatus, the inkjet recording apparatus including: an aqueous ink; a recording head including an ink flow path in which the aqueous ink flows and including an ejection orifice configured to eject the aqueous ink; and a recovery mechanism configured to recover an ejection state of the aqueous ink from the ejection orifice by applying a pressure to the ink flow path inside the recording head. The aqueous ink contains resin particles each dyed with a basic dye exhibiting fluorescence and a water-soluble resin. The resin particles are each formed of a resin having an anionic group-containing unit. The water-soluble resin has an anionic group-containing unit.

Abstract: An aqueous ink for an ink jet including a silver particle that contains (i) a first organic monocarboxylic acid having a pKa of 4.60 or more and (ii) a second organic monocarboxylic acid having a pKa of less than 4.60 and having a carbon number of 2 or less.

Abstract: An aqueous ink containing silver particles, a first reducing agent and a second reducing agent, wherein the first reducing agent is a compound that has an oxidation-reduction potential R1 (mV) satisfying R1<0, and the second reducing agent is a compound that has an oxidation-reduction potential R2 (mV) satisfying R2?0 and that is at least one selected from a group consisting of tertiary amines and polyhydric alcohols in which a plurality of hydroxy groups are included in one of two structures divided according to a position between any one of two adjacent carbon atoms of the longest carbon chain in the molecule.
