There is disclosed a liquid ink comprising a photo acid generating agent that generates an acid upon irradiation with light, a coloring component, and at least one kind of a solvent that is polymerized in the presence of an acid. It is preferable that the amount of the photo acid generating agent contained in the liquid ink falls within a range of between 1 part by weight and 10 parts by weight relative to 100 parts by weight of the solvent, the coloring component consists of a pigment, and the solvent contains at least 50 parts by weight of an acid polymerizable compound, the acid polymerizing compound polymerizing in the presence of the acid, having an alicyclic skeleton and/or an aliphatic skeleton having a viscosity of 50 mPa·s or less and a boiling point of 150°C or more under room temperature and atmospheric pressure.
本发明公开了一种液体油墨,该油墨由在光照射下产生酸的光酸生成剂、着色成分和至少一种在酸存在下聚合的溶剂组成。相对于 100 重量份的溶剂,液体油墨中所含的光酸生成剂的量最好在 1 重量份到 10 重量份之间,着色成分由颜料组成、溶剂中含有至少 50 份(重量)的可酸聚合化合物,该酸聚合化合物在酸存在下聚合,具有脂环族骨架和/或脂肪族骨架,在室温和常压下粘度为 50 mPa-s 或更低,沸点为 150°C 或更高。
