    Abstract: The invention provides an ink composition comprising (A) a polymerization initiator; (B) an ester or amide of (meth)acrylic acid having a 1,3-dioxolane ring skeleton or a 1,3-dioxane ring skeleton; and (C) a colorant; wherein the content of component (B) in the ink composition is in a range of 3 to 35% by mass on the basis of the total mass of the ink composition. The invention further provides an inkjet recording method and a method for producing a planographic printing plate, each of which includes at least (I) ejecting the ink composition onto a hydrophilic support and (II) curing the ink composition by irradiating the ejected ink composition with active radiation so as to form a hydrophobic image region on the hydrophilic support. The invention furthermore provides a planographic printing plate formed by the method for producing a planographic printing plate.
