Abstract:
Provided is an actinic radiation-curable inkjet ink that undergoes sol-gel phase transfer and contains a dye, a gelling agent, a photopolymerization compound and a photopolymerization initiator. The actinic radiation-curable inkjet ink includes a photopolymerizable compound A, which is a (meth)acrylate having hydroxyl groups; a photopolymerizable compound B, which is a (meth)acrylate compound having a molecular weight within a range of 300 to 1,500 and an intramolecular structure (—CH2—CH2—O—)m (where m is an integer between 3 and 14); and a (meth)acrylate compound C, which has a molecular weight within a range of 280 to 1,500 and a C log P value within a range of 4 to 7. The ink contains, in terms of the mass of the entire ink, 1 to 15 mass % of photopolymerizable compound A, 30 to 70 mass % of photopolymerizable compound B, 10 to 40 mass % of photopolymerizable compound C, and 2 to 10 mass % of gelling agent.
