Abstract
An ink set including an undercoat composition containing at least one of a polymerizable monomer A including a polymerizable monomer A1 having a C log P value of 2.0 or less or an alkali-soluble polymer, and a surfactant, and an ink containing a polymerizable compound B, wherein, in the polymerizable monomer A, a ratio of a monofunctional polymerizable monomer is 30 mass % or more, the undercoat composition has an isocyanate compound content of less than 10 mass %, a content of the alkali-soluble polymer relative to a mass of a solid content of the undercoat composition is 1 mass % to 20 mass %, relative to a unit molecular weight defined as 100, in the polymerizable compound B, a mass-ratio-based weighted mean of a number of functional groups per unit molecular weight is 0.65 or more, and the ink has a tri- or higher functional polymerizable compound content of less than 10 mass %.
