Document Type and Number:
Japanese Patent JP2012224699
Kind Code:
A
Abstract:

To provide an active energy ray-curable inkjet ink which has high radiation curing sensitivity, has reduced variation in the radiation curing sensitivity even being preserved over a long period and can obtain high injection stability, and an inkjet recording method.

In the active energy ray-curable inkjet ink including at least two kinds of polymerizable compounds each having polymerizable unsaturated bonds, the maximum value of a difference between the charges of carbon atoms constituting the respective polymerizable unsaturated bonds of at least two kinds of polymerizable compounds is 0.24 to 0.40, and further, the ink has an acid value of ≥0.2 mgKOH/g and an amine value of ≥0.2 mgKOH/g.
