Abstract
The present invention provides an active radiation curable ink composition including: (A) a polymer having two or more acidic groups or two or more basic groups; (B) a polymerizable monomer having a substituent group capable of forming a counter salt with the acidic group or basic group of the polymer (A); (C) a photo-polymerization initiator; and (D) a polymerizable monomer having a different structure from the polymerizable monomer (B).
Claims8
An active radiation curable ink composition, comprising:
- a polymer (A) having two or more acidic groups or two or more basic groups;
- a polymerizable monomer (B) having a substituent group capable of forming a counter salt with the acidic groups or the basic groups of the polymer (A);
- a photo-polymerization initiator (C);
- and
- a polymerizable monomer (D) having a different structure from the polymerizable monomer (B),
- wherein an amount of the substituent group of the polymerizable monomer (B) capable of forming a counter salt is in the range of from 0.2 to 1, in terms of equivalence, with respect to the amount of the acidic groups or the basic groups of the polymer (A) that has two or more acidic groups or two or more basic groups.
