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.
