Check-resistant coated veneered article

Abstract

A coated veneered article has at least one visible wood veneer layer coated with a multilayer finishing system comprising a coating layer nearest the veneer layer comprising a cationically polymerized moiety or moiety polymerized via cationic and free radical cure mechanisms, and an outermost coating layer comprising a free radically polymerized moiety. The article exhibits less veneer checking than a veneered article coated only with free radically polymerized coating layers.

1 . A coated veneered article at least one visible surface of which comprises a wood veneer layer coated with a multilayer finishing system comprising a coating layer nearest the veneer layer comprising a cationically polymerized moiety or moiety polymerized via cationic and free radical cure mechanisms, and an outermost coating layer comprising a free radically polymerized moiety, and wherein the coated veneered article exhibits less veneer checking than a veneered article coated only with free radically polymerized coating layers. 
   
   
       2 . An article according to  claim 1  comprising a cationically polymerized clearcoat or stain atop the veneer layer. 
   
   
       3 . An article according to  claim 2  comprising a cationically polymerized filler atop the clearcoat or stain. 
   
   
       4 . An article according to  claim 3  comprising a cationically polymerized sealer atop the filler. 
   
   
       5 . An article according to  claim 1  comprising at least two subsurface layers comprising cationically polymerized moieties. 
   
   
       6 . An article according to  claim 1  comprising a cationically polymerized layer atop the veneer layer, a cationically and free radically polymerized layer atop the cationically polymerized layer, and a free radically polymerized topcoat atop the cationically and free radically polymerized layer. 
   
   
       7 . An article according to  claim 1  comprising a subsurface coating layer comprising a UV cured epoxide. 
   
   
       8 . An article according to  claim 1  comprising a subsurface coating layer comprising a UV cured epoxycyclohexanecarboxylate. 
   
   
       9 . An article according to  claim 1  comprising a subsurface coating layer comprising a cationically and free radically polymerized UV cured moiety. 
   
   
       10 . An article according to  claim 1  comprising a subsurface coating layer comprising a UV cured acrylated epoxide. 
   
   
       11 . An article according to  claim 1  comprising a medium density fiberboard core. 
   
   
       12 . An article according to  claim 1  comprising an ash, birch, cherry, mahogany, maple, oak, poplar, teak, hickory or walnut veneer layer. 
   
   
       13 . An article according to  claim 1  having a backside atop which is at least one layer comprising a UV cured cationically polymerized moiety. 
   
   
       14 . A coated veneered article at least one visible surface of which comprises a wood veneer layer coated with a multilayer finishing system comprising at least one subsurface layer comprising a UV cured cationically and free radically polymerized moiety and an outermost layer comprising a free radically polymerized moiety, wherein the coated veneered article exhibits less veneer checking than a veneered article coated only with free radically polymerized coating layers.
