Abstract
The present invention relates to a printing element comprising at least one polymer layer on a substrate which has photoimageable 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.
