Title:
活性エネルギー線硬化型インクジェットインク組成物
Document Type and Number:
Japanese Patent JP6890170
Kind Code:
B2
Abstract:
To provide an active energy ray-curable inkjet ink composition which is excellent in wettability and a re-discharge property.SOLUTION: An active energy ray-curable inkjet ink composition contains a radical-polymerizable monomer (A) and a photopolymerization initiator (B), where the radical-polymerizable monomer (A) contains at least (A-1) a monofunctional monomer having a surface tension at 25°C of 32 mN/m or less, (A-2) a difunctional monomer being alkanediol diacrylate and (A-3) a monofunctional monomer having an aromatic ring, a content of (A-1) the monomer in the ink composition is 5-40 mass%, and a mass ratio of (A-1) the monomer to (A-2) the monomer in the ink composition is 2:1 to 1:4.SELECTED DRAWING: None
