Method for the pictorial coloring of wood surfaces and a colored wood substrate

Abstract

In order to provide, in a contemporary manner, inlays in which the character of the wood is retained, a process method applies a stain containing acrylates or polyacrylates to a wood substrate in a first step. After a drying time, in a further step, a mordant dye that reactively binds with the wood substrate and with the stain that has penetrated into the wood substrate is applied to the wood substrate.

1 . A method for coloring a wood substrate, which comprises the steps of: 
 providing the wood substrate;    applying a stain containing a material seletected from the group consisting of acrylates and polyacrylates to the wood substrate; and    producing a motif structure by applying a mordant dye to the wood structure which reactively binds with the wood substrate and with the stain which previously has penetrated into the wood substrate.    
   
   
       2 . The method according to  claim 1 , which further comprises producing the stain from a mixture containing ethyl acrylate and butyl acrylate.  
   
   
       3 . The method according to  claim 1 , which further comprises forming the stain to be oil-free.  
   
   
       4 . The method according to  claim 1 , which further comprises forming the stain to be free of inorganic components.  
   
   
       5 . The method according to  claim 1 , which further comprises obtaining the stain from a stain concentrate having a solids content of less than 70%.  
   
   
       6 . The method according to  claim 1 , which further comprises obtaining the stain from a stain concentrate having a solids content of at least 30%.  
   
   
       7 . The method according to  claim 1 , which further comprises forming the stain to be water-soluble.  
   
   
       8 . The method according to  claim 1 , which further comprises using an anthraquinone dye as the mordant dye.  
   
   
       9 . The method according to  claim 8 , which further comprises using an alizarin dye as the mordant dye.  
   
   
       10 . The method according to  claim 1 , which further comprises performing a vapor deposition process for applying the mordant dye onto the wood substrate.  
   
   
       11 . The method according to  claim 10 , which further comprises using an intermediate carrier during the performing step.  
   
   
       12 . The method according to  claim 11 , which further comprises providing a sublimation element as the intermediate carrier with the mordant dye intended for conversion into a gaseous state.  
   
   
       13 . The method according to  claim 11 , which further comprises using a heatable press.  
   
   
       14 . A colored wood substrate, comprising 
 a wood substrate;    a stain containing a material seletected from the group consisting of acrylates and polyacrylates applied to said wood substrate; and    a mordant dye applied to said wood structure for reactively binding with said wood substrate and with said stain which has penetrated into said wood substrate resulting in a motif structure having a nonuniform coloring.
