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.

Claims Analysis

Total Claims: 15
Claim 1
Independent Claim 54 words
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.
Claim 2
Independent Claim 54 words
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.
Claim 3
Dependent Claim 24 words
The method of claim 1 wherein said master is in the form of a belt and said coating, curing, and removing are done continuously.
Claim 4
Dependent Claim 24 words
The method of claim 1 wherein said master is in the form of a cylinder and said coating, curing, and removing are done continuously.
Claim 5
Dependent Claim 22 words
The method of claim 1, further including the step of coating the relief side of said resin replica with a reflectance-enhancing substance.
Claim 6
Independent Claim 59 words
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.
Claim 7
Independent Claim 59 words
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.
Claim 8
Dependent Claim 24 words
The method of claim 5 wherein said master is in the form of a belt and said coating, curing, and removing are done continuously.
Claim 9
Dependent Claim 24 words
The method of claim 5 wherein said master is in the form of a cylinder and said coating, curing, and removing are done continuously.
Claim 10
Dependent Claim 22 words
The method of claim 5, further including the step of coating the relief side of said resin replica with a reflectance-enhancing substance.
Claim 11
Independent Claim 67 words
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.
Claim 12
Independent Claim 67 words
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.
Claim 13
Dependent Claim 24 words
The method of claim 9 wherein said master is in the form of a belt and said coating, curing, and removing are done continuously.
Claim 14
Dependent Claim 24 words
The method of claim 9 wherein said master is in the form of a cylinder and said coating, curing, and removing are done continuously.
Claim 15
Dependent Claim 22 words
The method of claim 9, further including the step of coating the relief side of said resin replica with a reflectance-enhancing substance.
