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.
Claims12
A method of forming resin replicas of surface relief holograms, comprising:
- providing a durable surface relief hologram master;
- coating said hologram master with a radiation-curable resin;
- curing said resin in contact with said hologram master by exposing said resin to radiation;
- and
- removing said resin in a cured state from said hologram master.
A method of forming resin replicas of surface relief holograms, comprising:
- providing a durable surface relief hologram master;
- forming a laminate of said master and a smooth material with radiation-curable resin therebetween;
- curing said resin in said laminate by exposing said resin to radiation;
- and
- separating said cured resin and said smooth material from said hologram master.
A method of making a holographic hot-stamping foil, comprising:
- providing a durable surface relief hologram master;
- forming a laminate of said master and a smooth carrier film with radiation-curable resin therebetween;
- radiation curing said resin in said laminate to form a replica of said master;
- separating said cured resin and said smooth material from said hologram master;
- and
- coating the relief surface of said replica with a hot-stamping adhesive.
