ABSTRACT:
There is disclosed an ultraviolet-curing coating composition for cans comprising (A) 10-85 parts by weight of a compound having alicyclic epoxy group(s) in the molecule, (B) 5-60 parts by weight of a compound having an oxetane ring of a specific structure, (C) 5-60 parts by weight of a compound having an oxetane ring and hydroxyl group in the molecule, (D) 5-60 parts by weight of a compound having either at least two oxetane rings or oxetane ring(s) and epoxy group(s) in the molecule, and (E) 0.01-20 parts by weight of a cation-polymerization initiator, which generates a cation when irradiated with ultraviolet rays, per 100 parts by weight of the total amount of the compounds (A), (B), (C) and (D); and a process for producing a coated metal can by coating this coating composition and curing by irradiation with ultraviolet rays.
This ultraviolet-curing coating composition can form a coating film which is excellent in processability, adhesivity, hardness, hardness in hot water, and coating film appearance such as levelling property.
