INK-JET PROCESS FOR PREPARATION OF LITHOGRAPHIC PRINTING PLATES

摘要

A fluid composition suitable for ink jetting upon a substrate, which includes a copolymer having a low surface energy and a plurality of tertiary amine sites, where the tertiary amine sites are at least partially neutralized with an acid; a nonionic or cationic surfactant; and water. The fluid composition may be used to prepare a printable media comprised of a substrate and an ink receptive thermoplastic image layer supported on the substrate; where the ink receptive layer contains a copolymer having a low surface energy and a plurality of tertiary amine sites, the amine sites being at least partially neutralized with an acid. The invention also relates to a method for preparing a printable media by applying a fluid composition onto a substrate having at least one basic surface by means of an ink jet printing apparatus; where the fluid composition contains a copolymer having a plurality of tertiary amine sites, the amine sites being at least partially neutralized with an acid, and drying the fluid composition.
