Laminate having color and metallic gloss, and method for production thereof

Abstract

A chromatic dye such as a heterocyclic, perinone or thioindigo dye is contained in an ABS resin, and this dye-containing resin is mixed/kneaded and then pelletized. The pellets are extrusion-molded to form an uncemented first resin layer, to which an uncemented second resin layer having metallic luster and provided with a metallic film formed by depositing a metal is attached, heated and pressed, whereby the uncemented first and second resin layers are cemented together and the dye present in the uncemented first resin layer is caused to migrate into the second resin layer to color it to such a degree that a color difference A E of not less than 0.8 is produced. Thereby a laminate having chromatic metallic luster on the second resin layer side is obtained.

1 . A chromatic metalescent laminate comprising a first resin layer and a metallic film containing a dye.  
     
     
         2 . A chromatic metalescent laminate comprising a first resin layer containing a dye, a metallic film and a second resin layer laminated in that order, 
 said second resin layer containing the dye which has migrated from the first resin layer, and    said laminate having chromatic metallic luster at least on its second resin layer side.    
     
     
         3 . A chromatic metalescent laminate according to  claim 2 , wherein said metallic film is formed by deposition on said first resin layer or said second resin layer.  
     
     
         4 . A chromatic metalescent laminate according to  claim 2 , wherein said second resin layer produces a color difference of not less than 0.8 on the migration of said dye thereinto.  
     
     
         5 . A chromatic metalescent laminate comprising a first resin layer containing a dye and a metallic film, said metallic film containing the dye which has migrated from the first resin layer, and said laminate having chromatic metallic luster at least on its metallic film side.  
     
     
         6 . A chromatic metalescent laminate according to  claim 5 , wherein said metallic film produces a color difference of not less than 0.8 on the migration of said dye thereinto.  
     
     
         7 . A method of producing a chromatic metalescent laminate as defined in  claim 2 , which comprises heating an uncemented first resin layer containing a dye and an uncemented second resin layer having a metallic film formed on at least one side thereof, thereby cementing together said first and second resin layers so that the first resin layer faces the metallic film, while causing part of said dye to migrate into the second resin layer.  
     
     
         8 . A method of producing a chromatic metalescent laminate as defined in  claim 2 , which comprises heating a cemented laminate of a cemented first resin layer containing a dye, a metallic film and a cemented second resin layer laminated in that order, thereby causing part of said dye to migrate into the cemented second resin layer.
