Abstract: Provided is a photocurable ink composition including a resin which has an amine structure having an α-hydrogen atom and contains at least one selected from the group consisting of an alkylthio group, an alkylenethioalkylene group, and a mercapto group and at least one selected from the group consisting of a fluorinated hydrocarbon group, a polysiloxane group, and a hydrocarbon group having 12 or more carbon atoms; at least one of a monofunctional radically polymerizable monomer or a bifunctional radically polymerizable monomer; and a photopolymerization initiator.

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: A photocurable ink composition is provided, the composition including: a resin that includes at least one of a structural unit (1) below or a structural unit (2) below; and at least one of a monofunctional radical-polymerizable monomer or a bifunctional radical-polymerizable monomer, in which a total content of the monofunctional radical-polymerizable monomer and the bifunctional radical-polymerizable monomer is 50% by mass or more relative to a total amount of the photocurable ink composition.
