Abstract

There is disclosed an ink for ink jet recording, comprising a photo-acid generating agent which is capable of generating an acid as it is irradiated with light, a colorant, and an acid-polymerizable solvent which can be polymerized in the presence of an acid. In this ink, the content of the photo-acid generating agent is not less than 5 parts by weight per 100 parts by weight of the acid-polymerizable solvent, and the acid-polymerizable solvent comprises an aliphatic epoxy compound represented by the following general formula (1) and an oxetane ring-containing compound: R1-CH2-C(CH3)2-CH2-R1 (wherein R1 is glycidyl ether group).

Description

technical field [0001] The present invention relates to an inkjet recording ink. Background technique [0002] When a large number of copies of printed matter is required, such as printed copies of local advertisements and business flyers, a forming plate printing press is usually used to meet this demand. However, in recent years, along with the diversification of needs, on-demand printing machines capable of fast copying and minimizing inventory have been used more and more, gradually replacing the above-mentioned conventional printing machines. Regarding such on-demand printers, since inkjet printers can achieve high-speed and high-quality printing, inkjet printers are expected to be used as on-demand printers. [0003] As for the technique of realizing high-definition image printing with an inkjet printer, known methods use solvent-based inks or solvent-based liquid toners, both of which contain pigments and organic solvents, in the same manner as formplate printers.
