  The present invention provides a novel ethylenically unsaturated compound which is highly sensitive to scanning exposure due to an ultraviolet to near-infrared laser and is cured to give good physical properties; a light sensitive composition providing good developability and high sensitivity and forming a high strength layer; a planographic printing plate material having advantages that good developability, high sensitivity and high strength layer are obtained, particularly a planographic printing plate material requiring no developing machine which are mounted on a printing press without any development, followed by printing and which provides excellent developability on a printing press and printing durability; and a printing process. The ethylenically unsaturated compound has in the molecule a photo-oxidation group and a polymerizable ethylenically unsaturated bond, and has a predetermined solubility in water or an aqueous alkali solution. The planographic printing plate material is characterized in that it comprises a support and provided thereon, a light sensitive layer containing the ethylenically unsaturated compound, a polyhalogen compound as a photopolymerization initiator, a water-soluble polymer binder as a polymer binder and an infrared absorbing agent.
