PROBLEM TO BE SOLVED: To obtain the subject composition giving a cured coating film having excellent adhesivity to oily ink, etc., and useful for the coating of the surface of a can, bottle, etc., of drink by compounding an epoxy compound which is liquid at normal temperature, a specific acrylic polymer and a photo-cationic polymerization initiator. SOLUTION: This composition contains (A) an epoxy compound which is liquid at normal temperature, (B) an acrylic polymer having a contact angleθof 70-90 deg. with water and (C) a photo-cationic polymerization initiator (e.g. an aryl diazonium salt). The component A preferably contains >=50 wt.% of an alicyclic epoxy compound. The alicyclic epoxy compound preferably has cyclohexene oxide or cyclopentene oxide group. The weight ratio of the component A to B (A:B) is preferably 99:1 to 50:50. The amount of the component C is preferably 1-10 wt.% based on the sum of the components A and B. The monomer to give the component B is e.g. methyl (meth)acrylate.
