Radiation-curable ink jet composition and ink jet printing method

Abstract

A radiation-curable ink jet composition contains at least one monomer A represented by general formula (I): CH2═CR1—COOR2—O—CH═CH—R3, wherein R1 represents a hydrogen atom or a methyl group, R2 represents a divalent organic moiety having a carbon number of 2 to 20, and R3 represents a hydrogen atom or a monovalent organic moiety having a carbon number of 1 to 11. The composition also contains a cyclic, linear, or branched monomer B containing a (meth)acryloyloxy or (meth)acryloyl group in which the total number of nitrogen atoms and oxygen atoms other than the oxygen atoms contained in the (meth)acryloyloxy or (meth)acryloyl group is at least 2, and at least one monomer C represented by the following general formula (II): wherein n represents an integer of 2 to 6. The total content of monomer A is 10% by mass or more relative to the total mass of the ink jet composition.
