    Abstract: Provided are a photocurable ink composition including a resin which contains an amino group having one or more hydrogen atoms on a carbon atom at an ca-position and having an amine value of 3.5 mmol/g to 12 mmol/g, and a radically polymerizable monomer, in which the radically polymerizable monomer contains at least one of a monofunctional radically polymerizable monomer or a bifunctional radically polymerizable monomer, a total content of the monofunctional radically polymerizable monomer and the bifunctional radically polymerizable monomer is 50% by mass or greater with respect to a total mass of the photocurable ink composition, and a content of a radically polymerizable monomer containing an acid group in the radically polymerizable monomers is 1.5 mmol or less per 100 g of the photocurable ink composition; and an image forming method performed by using the photocurable ink composition.

    Abstract: An aqueous dispersion is provided, the aqueous dispersion including: a microcapsule including a core and a shell that has a three-dimensionally crosslinked structure including (a) at least one selected from the group consisting of a urethane bond and a urea bond and (b) an anionic group and a nonionic group as hydrophilic groups, in which at least one of the shell or the core has a thermal-polymerizable group; and water, in which the nonionic group is a group (W) represented by Formula (W) below, *RW1—OnwRW2  Formula (W) in which, in Formula (W), RW1 represents an alkylene group that has 1 to 6 carbon atoms and that may be branched, RW2 represents an alkyl group that has 1 to 6 carbon atoms and that may be branched, nw represents an integer of 2 to 200, and * represents a linkage position.

    Abstract: Provided are an aqueous dispersion including a microcapsule and water, the microcapsule including: a shell having a three-dimensional cross-linked structure containing: at least one bond selected from a urethane bond or a urea bond; and an anionic group and a nonionic group as hydrophilic groups; and a core, at least one of the shell having a photopolymerization initiating group or the core containing a photopolymerization initiator being satisfied, and at least one of the shell having a polymerizable group or the core containing a polymerizable compound being satisfied; a method for manufacturing the same; and an image forming method using the aqueous dispersion.
