Method for producing coated paper with pearlescent effect

Abstract

A method for producing coated paper with pearlescent effect, sequentially comprising the following operating steps: a deposition, on at least one side of a paper medium, of at least one layer of coating; an additional deposition, over the at least one layer of coating, of a coating with pearlescent effect by a rotogravure/flexographic device.

1 - 10 . (canceled)  
   
   
       11 . A method for producing coated paper with pearlescent effect, comprising sequentially the steps of: 
 performing a first deposition, on at least one side of a paper medium, of at least one layer of coating;    performing a second deposition, over said at least one layer of coating, of a coating with pearlescent effect by means of a rotogravure/flexographic device.    
   
   
       12 . The method for producing coated paper with pearlescent effect according to  claim 11 , wherein said coating with pearlescent effect comprises at least nitrocellulose resins, mica-based pigments, and a solvent.  
   
   
       13 . The method for producing coated paper with pearlescent effect, according to  claim 11 , wherein said rotogravure/flexographic device comprises at least one deposition roller.  
   
   
       14 . The method for producing coated paper with pearlescent effect according to  claim 13 , wherein said at least one deposition roller has a plurality of deposition cells at its outer side wall.  
   
   
       15 . The method according to  claim 11 , wherein said paper medium has a thickness comprised between 70 and 400 microns.  
   
   
       16 . The method for producing coated paper with pearlescent effect according to  claim 11 , wherein said first deposition step comprises deposition of a first and second layers of coating, said first layer of coating having a thickness comprised between 6 and 12 microns, and said second layer of coating having a thickness comprised between 1 and 8 microns.  
   
   
       17 . The method for producing coated paper with pearlescent effect according to  claim 16 , wherein said deposition of said first and second layers of coating is performed at both sides of said paper medium.  
   
   
       18 . The method for producing coated paper with pearlescent effect according to  claim 17 , wherein said second deposition of a coating with pearlescent effect is performed over both of said first depositions.  
   
   
       19 . The method for producing coated paper with pearlescent effect according to  claim 11 , wherein said second deposition of a coating with pearlescent effect has a thickness comprised between 2 and 6 microns per side.  
   
   
       20 . A coated paper with pearlescent effect, comprising a paper medium that has, at at least one side, at least one layer of coating and, above said at least one layer of coating, at least one layer of coating with pearlescent effect.
