摘要： A coating composition which comprises (A) an actinic radiation curable resin, which is the ring-opening addition reaction product of (a) a polyester resin having hydroxyl functionality and (b) a compound having both a cyclic ether group and a (meth)acryloyl group, and preferably (B) at least one compound having at least one radical-polymerizable unsaturated group in a molecule. The composition also preferably comprises (C) a photopolymerization initiator and (D) photosensitizer. A process for obtaining the composition and the coating of metal substrates are also disclosed, as well as coated metal substrates that are particularly useful as cans for beverages, soft drinks, juices, and other food products. The coating compositions and the resulting cured coatings and coated substrates exhibit improved processability, adhesivity, hardness, mar resistance, appearance and retort resistance.
