A photocurable ink composition for ink jet printing, which has excellent storage stability and ejection properties, is curable by ultraviolet rays using a light emitting diode (LED) as a light source, and has good adhesion, flexibility and tackiness. To get. A photocurable ink composition for inkjet printing, comprising a photopolymerizable compound and a photopolymerization initiator , A. 2- (allyloxymethyl) methyl acrylate is contained in the total photopolymerizable compound in an amount of 5 to 40% by mass, B. Containing 5 to 20% by mass of a polyfunctional monomer and / or polyfunctional oligomer having a glass transition temperature of 0 ° C. or lower in the total photopolymerizable compound; C. containing a monomer and / or oligomer having an amino group and / or an amide group, D. The viscosity of the ink composition is 30 mPa · s or less at 25 ° C., A photocurable ink composition for ink jet printing satisfying A to D. [Selection figure] None |
