Inkjet receptive and laser printable coating for holographic and metallic media

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.

1 . An optical medium having a substrate defined by a paper layer, an image layer disposed on said paper layer, and a primer layer disposed on said image layer, said optical medium comprising: 
 a receptive coating disposed on said primer layer of said substrate.    
     
     
         2 . The optical medium of  claim 1 , wherein said receptive coating comprises, 
 a binder,    a first modifying agent incorporated into said binder, and    a second modifying agent incorporated into said binder.    
     
     
         3 . The optical medium of  claim 1 , wherein said receptive coating is configured to receive an inkjet printing, a laser printing, a printing from a hot stamp device, or a combination of the foregoing printings.  
     
     
         4 . The optical medium of  claim 1 , further comprising a topcoat applied over said receptive coating after said receptive coating has been printed.  
     
     
         5 . A receptive coating for an inkjet printing device or a laser printing device, said receptive coating comprising: 
 a binder;    a polyvinyl alcohol resin incorporated into said binder; and    a polyvinyl pyrrolidone resin incorporated into said binder.    
     
     
         6 . The receptive coating of  claim 5 , wherein said binder comprises an acrylic resin, a polyester resin, a urethane resin, a vinyl resin, or a combination of the foregoing materials.  
     
     
         7 . The receptive coating of  claim 5 , wherein said polyvinyl alcohol resin comprises about 7 to about 20 weight percent polyvinyl alcohol.  
     
     
         8 . The receptive coating of  claim 5 , wherein said polyvinyl alcohol resin comprises about 9 to about 17 weight percent polyvinyl alcohol.  
     
     
         9 . The receptive coating of  claim 5 , wherein said polyvinyl alcohol resin comprises about 11 to about 15 weight percent polyvinyl alcohol.  
     
     
         10 . The receptive coating of  claim 5  wherein said polyvinyl pyrrolidone resin comprises about 40 to about 68 weight percent polyvinyl pyrrolidone.  
     
     
         11 . The receptive coating of  claim 5 , wherein said polyvinyl pyrrolidone resin comprises about 48 to about 60 weight percent polyvinyl pyrrolidone.  
     
     
         12 . The receptive coating of  claim 5 , wherein said polyvinyl pyrrolidone resin comprises about 51 to about 57 weight percent polyvinyl pyrrolidone.  
     
     
         13 . The receptive coating of  claim 5 , further comprising a water-based carrier in which said inkjet receptive coating is dispersed.  
     
     
         14 . The receptive coating of  claim 13 , wherein said water-based carrier comprises an alcohol.  
     
     
         15 . The receptive coating of  claim 13 , wherein said water-based carrier comprises up to about 25% isopropanol.  
     
     
         16 . The receptive coating of  claim 5 , wherein said receptive coating is applied as a single layer.  
     
     
         17 . The receptive coating of  claim 5 , wherein said receptive coating is configured to receive an inkjet printing, a laser printing, a hot stamp printing, or a combination of the foregoing printings.
