ACTIVE ENERGY RAY-CURING INK FOR INKJET RECORDING AND METHOD FOR FORMING COATED FILM

摘要

PROBLEM TO BE SOLVED: To provide an active energy ray-curing ink satisfying characteristics suitable for an inkjet apparatus having nozzles arranged at a high density in good balance and to provide a method for forming a dense coated film having excellent adhesiveness to a substrate and excellent water resistance.

SOLUTION: The active energy ray-curing ink for inkjet recording is characterized as comprising a zwitterion compound having at least one phenolic hydroxy group and at least one cyclic aliphatic sulfonium group in the molecule. The method for forming the coated film is characterized as having at least (1) a step of jetting the ink from jetting ports of an inkjet head and making the ink stick to a prescribed part of the substrate and (2) a step of irradiating the substrate obtained in the step (1) with active energy rays in a step of forming the coated film of the ink.
