摘要：
A photo-curable ink contains an oil-based liquid containing a polymerizable compound and a photopolymerization initiator, and an aqueous liquid containing water. When the photo-curable ink is stirred at a rotational speed of 15000 rpm or more for 3 minutes and then allowed to stand at 25° C. for one hour or more, droplets formed with the aqueous liquid are dispersed in the oil-based liquid without layer separation between the oil-based liquid and the aqueous liquid.
