The present invention aims to provide a photocurable ink composition for ink-jet printing having excellent photocurability, favorable adhesiveness to a substrate, and excellent elongation property and flexibility. The present invention relates to a photocurable ink composition for ink-jet printing containing: a ketone resin having a hydroxyl group; as a photopolymerizable compound, (a) aromatic ring-containing acrylate, which is represented by the following formula (I), and isobornyl acrylate and/or (b) trimethylcyclohexane acrylate, (in the formula, "R" represents an aromatic ring in which a hydrogen atom may be substituted by an alkyl group, and "n" represents an integer from 0 to 5); and a photopolymerization initiator, a blending ratio of said aromatic ring-containing acrylate to said isobornyl acrylate being 70/30 to 30/70 by mass, and a content of said ketone resin having a hydroxyl group being 8 to 20% by mass.
