Abstract

Provided are: an inkjet ink composition containing water and particles, the particles including an anionic group-containing polymer, a photoacid generator, and a sensitizer, wherein the value obtainedby subtracting the photoacid generator amount G, which is the number of millimoles of the photoacid generator present in 1 g of the particles, from the anion group value A, which is the number of millimoles of the anionic group present in 1 g of the particles, is -0.20 to 0.20, and the sensitizer is at least one of the compounds represented by formulae (S1) to (S3); a method for producing the inkjet ink composition; and an image-forming method. R11, R12, R21, R31, R32, R33, and R34 each independently represent a substituent, n11, n12, n21, n33, and n34 each independently represent an integerof 0-4, and R22 and R23 each independently represent a hydrogen or a substituent.

Description

technical field [0001] The present disclosure relates to an inkjet ink composition, a manufacturing method thereof, and an image forming method. Background technique [0002] Conventionally, inkjet ink compositions containing water and particles containing polymers have been known. [0003] For example, Patent Document 1 discloses a gel particle that is excellent in dispersibility and redispersibility when cured, and can be cured with high sensitivity and can obtain a film (for example, an image) with excellent film strength. , has a polymerizable group, has a three-dimensional crosslinked structure including at least one bond selected from urethane bonds and urea bonds, and contains a photopolymerization initiator, and further discloses an ink containing the gel particles and water combination. [0004] In addition, Patent Document 2 discloses an aqueous ink composition having good fixability and ejectability, comprising a) an aqueous medium, b) a compound having an ethyl...
