The present invention relates to a low-viscosity, excellent color reproducibility, and a small amount of residual components in a cured film, particularly a 1-pass curable ink, which can be used in a wide variety of labels especially for foods, cosmetics and pharmaceuticals. The purpose is to provide. An active energy ray-curable ink-jet ink composition comprising at least 2- (2-vinyloxyethoxy) ethyl acrylate, dipropylene glycol diacrylate, and a pigment, which comprises 2- (2-vinyloxyethoxy acrylate). ) The content of ethyl is 36 to 65% by weight in the total amount of ink, the content of dipropylene glycol diacrylate is 31 to 63% by weight in the total amount of ink, and the content of the pigment is 1 to 3 in the total amount of ink. c is an active energy ray curing in which c is a pigment concentration at which the average value of absorbance at 320 to 380 nm is 1, measured by diluting the ink composition 2000 times with dipropylene glycol diacrylate. Type ink-jet ink composition. [Selection figure] None |
