Powder coating

Abstract

The combination of powder coatings usable in a coating method comprising mixing two or more powder coatings of which each color is different, wherein each of the powder coatings fuses with each other and is heat-cured, to thereby give a coating film having a homogenous hue. A powder coating composition comprising two or more powder coatings of which each color is different, wherein each of the powder coatings fuses with each other and is heat-cured, to thereby give a coating film having a homogenous hue. A coating method comprising the steps of (a) applying to a substrate two or more powder coatings, of which each color is different; (b) heating to fuse with each other each of the two or more powder coatings applied in step (a); and (c) curing the resulting fused product in step (b), to give a coating film having a homogeneous hue.

What is claimed is:  
     
         1 . A coating method comprising the steps of: 
 (a) applying to a substrate two or more powder coatings, of which each color is different;    (b) heating to fuse with each other each of said two or more powder coatings applied in step (a); and    (c) curing the resulting fused product in step (b), to give a coating film having a homogeneous hue.    
     
     
         2 . The coating method according to  claim 1 , wherein said step (c) is carried out by heat-curing the resulting fused product in step (b).  
     
     
         3 . The coating method according to  claim 1 , wherein said step (c) is carried out by irradiating light to the resulting fused product in step (b).  
     
     
         4 . A coating film or a coated substrate having a homogeneous hue prepared by applying to a substrate two or more powder coatings, of which each color is different, according to a combination of powder coatings, wherein each of said powder coatings fuses with each other and is heat-cured, to thereby give a coating film having a homogenous hue.  
     
     
         5 . A coating film or a coated substrate having a homogeneous hue prepared by applying to a substrate two or more powder coatings, of which each color is different, according to the coating method as defined in  claim 1.
