Abstract: One embodiment of an optical medium includes a substrate having a paper layer, an image deposited or otherwise disposed at the paper layer, a primer layer deposited or otherwise disposed at the image layer, and a receptive coating deposited or otherwise disposed at the primer layer of the substrate. One embodiment of an inkjet receptive coating or laser printable coating includes a binder (e.g., an acrylic resin) having a polyvinyl alcohol resin and a polyvinyl pyrrolidone resin incorporated therein. One manner of incorporating the resins into the binder is by blending the resins into the binder.

Abstract: An ink jet printable coating for holographic paper is presented. The coating utilizes a high dyne primer layer and a secondary layer. The secondary layer includes a plurality of microscopic pores which are preferably 1 to 6 microns in diameter. The pores are sized to allow ink jet ink to penetrate during the printing process. The coating is compatible to both water based and solvent based inks. The pores serve to provide a site to which the ink jet ink can anchor and set, thus preventing the ink from running when initially applied to the surface and speeding the rate of ink drying. Additionally, the secondary layer is porous enough to absorb the ink as it dries. The deeper the secondary layer, the further to ink can penetrate for greater adhesion to the surface and for faster drying.
