US Patent:

6355302, Mar 12, 2002

Filed:

Dec 10, 1999

Appl. No.:

09/459134

Inventors:

John L. Vandenberg - Maplewood MN
Britton G. Billingsley - St. Paul MN
Joey L. Reule - Cottage Grove MN
Frederick J. Fox - Oakdale MN

Assignee:

3M Innovative Properties Company - St. Paul MN

International Classification:

B05D 506

US Classification:

4271634, 216 7, 156345

Abstract:

Simplified continuous processes are disclosed for converting standard woven or nonwoven fabric into reflectorized fabric in a continuous fashion and in bulk quantities. These processes are easily capable of achieving reflectivities of well over 100 cd/(luxÂm ). In the processes, an extended length of fabric is provided such as by unwinding an input roll of fabric to be reflectorized, and the fabric is passed through a station that applies a coating of binder material to the fabric. The fabric then passes through a station where aluminum-coated beads are applied to the coating of binder material. An etching station removes exposed portions of the aluminum coating from the beads after the binder material is allowed to substantially solidify. End-use materials other than fabrics but suitable for enhancing personal conspicuity can be reflectorized in the same way.

International Classification:

B32B 706
B32B 714

US Classification:

428 401

Abstract:

A security laminate comprising (1) a protective layer having a first and a second surface, (2) a pattern of low adhesion coating bonded to a portion of the second surface of the protective layer, (3) at least one emblem bonded to a portion of the low adhesion coating/protective layer composite, (4) an adhesive bonded to the emblem layer/low adhesion coating/protective layer composite, and (5) a primer is not included between the low adhesion coating and emblem layers; wherein the bond between the emblem and the protective layer and the bond between the adhesive layer and protective layer are the most tenacious bonds, and the bond between the low adhesion coating and the protective layer is the least tenacious, whereby the emblems and adhesive layers are damaged in the pattern of the low adhesion coating during delamination. Also, secured documents comprising such security laminates and a method for securing documents utilizing such security laminates.
