Filed:

Nov 8, 2002

Appl. No.:

10/290762

Inventors:

Robert Jordan - St. Paul MN, US
Craig Kapfer - Maplewood MN, US
Scott Van Wert - St. Paul MN, US

Assignee:

3M Innovative Properties Company

International Classification:

B41N001/00

US Classification:

101/395000

Abstract:

An adhesive tape for flexographic printing including a first adhesive layer, a substrate on the first adhesive layer, and a second adhesive layer on the substrate. The substrate preferably includes a polymeric film layer and a foam layer, wherein the topography of the first and second adhesive layers is substantially independent of the topography of the polymeric film layer. The polymeric film is preferably substantially smooth, and at least one of the first and second adhesive layers is preferably substantially continuous and includes a regular pattern of permanent grooves. The grooves preferably have a depth of about 4 m to about 200 m, and a width of about 4 m to about 200 m.

Appl. No.:

14/113531

Inventors:

James E. Garbe - Stillwater MN, US
Craig A. Kapfer - Maplewood MN, US

International Classification:

C09D 5/33

US Classification:

524874

Abstract:

A composition system includes a first portion having an isocyanate monomer and an acrylate monomer and a second portion includes a secondary amine monomer having at least two carbon atoms bonded to a nitrogen atom of the secondary amine monomer and at least one of the carbon atoms has two carbon atoms bonded to the carbon atom. The second portion includes a thermal acrylate polymerization initiator. The composition system can be utilized as pavement marking.
