Document Type and Number:
WIPO Patent Application WO/2024/070376
Kind Code:
A1
Abstract:
Provided are: an active energy ray-curable ink composition, with which an obtained printed object exhibits excellent processability able to be used in DR can applications and exhibits anti-blocking properties that allow printed objects to be piled up even if a varnish is not applied; and a printed object. This active energy ray-curable ink composition contains a pigment, a polyester resin, an acrylate monomer and a photopolymerization initiator. The acrylate monomer includes an acrylate monomer having an isocyanurate ring, a difunctional acrylate and a monofunctional acrylate. The content of the acrylate monomer having an isocyanurate ring is 25-50 mass% of the total amount of acrylate monomers. The content of the monofunctional acrylate is 8-30 mass% of the total amount of acrylate monomers. The total content of the monofunctional acrylate and the difunctional acrylate is 30-75 mass% of the total amount of acrylate monomers.
