Abstract
A formula and process to manufacture a lift-off correction ribbon in which the bonding material layer is cured by ultraviolet radiation. The bonding material is not normally tacky, but bonds under impact. The radiation curing eliminates solvents and their associated handling and pollution problems. The preferred bonding material formula is primarily a mixture of dilinoleic acid and trimethylol propane triacrylate with an ultraviolet ionization initiator.
