Claim 0:
1. An ink composition for photo-curable ink jet printing, comprising:
(A) at least one selected from the group consisting of hexanediol acrylate, 3-methyl-1,5-pentanediol diacrylate, dipropylene glycol diacrylate, and hydroxy pivalic acid neopentyl glycol diacrylate;
(B) at least one of vinyl amide monomer and acryloyl amine monomer;
(C) an acrylated amine compound having two photopolymerizable functional groups and two amino groups in a molecule; and
(D) a monofunctional monomer; and a photopolymerization initiator,
wherein the monofunctional monomer of the (D) component excludes vinyl amide monomer of the (B) component,
wherein a content of the (A) component is 51.10 to 70% by mass in the ink composition for photo-curable ink jet printing,
wherein a content of the (B) component is 5 to 20% by mass in the ink composition for photo-curable ink jet printing,
wherein a content of the (C) component is 0.1 to 15% by mass in the ink composition for photo-curable ink jet printing,
wherein a content of the (D) component is 5 to 16.8% by mass in the ink composition for photo-curable ink jet printing, and
wherein a viscosity at 25° C. is 200 mPa·s or less.
