Abstract

The invention provides a hydrophilic film obtained by curing, by at least one energy source selected from heat and light, a composition comprising a compound that has, in a molecule thereof, two or more ring structures selected from the group consisting of five-membered structures and six-membered structures, wherein the ring structures have a hydrophilic group. The invention further provides a planographic printing material having at least a substrate and the hydrophilic film formed on the substrate. The invention further provides a method for forming a planographic printing plate including at least forming an ink receiving portion on a planographic printing material by applying a hydrophobic material by an ink jet recording process.
