Abstract

A patterned element for use in an embossing and adhesive application process. The patterened element comprises a material having an pattern disposed thereon, wherein the material comprises a polymer and has a Shore A hardness of greater than about 70, and has a critical surface energy of less than about 30 dynes/cm.

Claims

1. A patterned element for use in an embossing and adhesive application process, said patterned element whose surface comprises a material having a pattern disposed thereon, said material comprising a polymer and has a Shore A hardness of greater than about 70, a surface roughness of less than about 30 microinches (0.8 microns) and has a critical surface energy of less than about 30 dynes/cm.

2. The patterned element according to claim 1 wherein said material has a peel force of less than about 500 g/inch, a Taber abrasion weight loss of less than about 300 mg, wherein said element is patterned by laser engraving.

3. The patterned element according to claim 1 wherein said material further comprises from about 2% to about 50% by weight of a critical surface energy reducer.

4. The patterned element according to claim 3 wherein said critical surface energy reducer is selected from the group consisting of oils, waxes, gums, resins, particles containing silicone and/or fluorine and combinations thereof.

5. The patterned element according to claim 1 wherein said polymer is selected from the group consisting of silicones, fluoropolymers, polyurethane, nitrile rubbers, isoprene rubber, thermoplastic elastomers, EP rubber, SER, EPDM, epoxides, polychloroprene and mixtures thereof.

6. The patterned element according to claim 5 wherein said polymer is copolymers containing silicone and/or fluorine.

7. The patterned element according to claim 1 is selected from the group consisting of a roll and a continuous belt.

8. The patterned element according to claim 1 wherein said material surrounds a curved body of a cylindrical core.
