US Patent:

8541162, Sep 24, 2013

Filed:

Sep 1, 2010

Appl. No.:

12/873584

Inventors:

Gary Delmar Jaycox - West Chester PA, US
Graciela Beatriz Blanchet - Boston MA, US
Nancy G. Tassi - Gibbstown NJ, US

Assignee:

E I du Pont de Nemours and Company - Wilmington DE

International Classification:

G03F 7/00
G03F 7/11
G03F 7/26

US Classification:

430300, 430322

Abstract:

The present invention relates to a printing element comprising at least one polymer layer on a substrate which has photoimagable constituents and a chemically functionalized polymer to make the polymer layer either more hydrophobic or hydrophilic. In one embodiment of the present invention, the printing element comprises two adjacent polymer layers on a substrate in which the photoimaged layer comprises a polymer chemically modified with hydrophobic fluoroalkyl side groups to provide differential wetting with hydrophilic inks.

International Classification:

G03F 7/031
B05D 1/38

US Classification:

428519, 427333, 428515

Abstract:

The present invention relates a printing element comprising at least one polymer layer which has photoimageable constituents and additions to make the polymer layer either hydrophobic or hydrophilic. The printing element may have two polymer layers on a substrate in which one of the layers comprises fluorinated acrylates or methacrylates.
