Abstract
The problems of applying ink jet inks to various known coating surfaces so as to overcome smearing, poor resolution and attack by water etc., is overcome by the use of the new ink jet receptive media. The media comprises in combination: (1) a waterproof ink jet receptive coating, (2) a primer coating, (3) a non-porous substrate, (4) a pressure sensitive adhesive coating, (5) a silicone coating and (6) a backer layer. The receptive coating comprises the combination of: (1) binder, (2) charge control agent, (3) cross-linking agent, (4) adhesion enhancing agent and (5) dispersant. The absorption of the ink jet ink to the substrate is maximized, thus attracting and fixing the ink and providing a waterproofing effect.
