Blanket materials for indirect printing method with varying surface energies via amphiphilic block copolymers

摘要

An intermediate transfer member containing a multi-block copolymer containing at least an A block and a B block, wherein the A block has a higher surface energy than the B block, and a method of forming an intermediate transfer member. A method of printing an image to a substrate including applying an ink onto the intermediate receiving member using an inkjet printhead; spreading the ink onto the intermediate receiving member; inducing a property change of the ink; and transferring the ink to a substrate.
