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