Abstract
Provided is an active energy ray-curable offset printing ink composition that can prevent occurrence of a slurring phenomenon. The active energy ray-curable offset printing ink composition includes a compound having an ethylenically unsaturated bond, a photopolymerization initiator, a colorant, and an extender pigment. The extender pigment has a median diameter (d50) of 1.0 to 2.0 μm measured by laser diffractometry. Printing with a reduced slurring phenomenon can be achieved using such an active energy ray-curable offset printing ink composition.
