高解像度で耐溶剤性の薄いエラストマー印刷版

摘要

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.
