To provide an electron beam-curable composition which can form a film which closely adheres to a polyolefin substrate without requiring a pretreatment step and to provide a method for forming a cured film excellent in adhesiveness on a polyolefin substrate.
This electron beam-curable composition contains a polymerizable compound having at least three ethylenic double bonds and a polymerizable compound having one or two ethylenic double bonds, the sum of contents of the double bonds being 5.0×10-3 mol/g or higher but 1.0×10-2 mol/g or lower based on the sum of amounts of the polymerizable compounds. The method for forming a cured film comprises forming a film from the composition on a polyolefin substrate and irradiating thus formed film with an electron beam.
