Abstract
Abstract A method of manufacturing surface relief holograms wherein an original surface relief hologram in the form of an endless loop or a drum is continuously coated with a radiation-curable resin. After curing, the resin bears a replica of the original hologram and it is continuously drawn off from the original as a sheet or film. The replica film becomes a hot-stamping foil when formed in contact with a carrier film, metallized, and coated with a hot-stamping adhesive.
