Embossed decorative injection-molded product and method of manufacturing the same

Abstract

The present invention relates to a decorated injection molded article having an embossed pattern comprising a surface layer comprising an acryl resin film, a printing layer provided on an inside of the surface layer, an adhesive layer provided on an inside of the printing layer and an injected resin layer, wherein a concavo-convex pattern is provided on the surface of the surface layer at a front face part and a side face part of the injection molded article by emboss processing and further to a method for producing the same, and the present invention provides a decorated injection molded article having an embossed pattern, in which a concavo-convex pattern is easily formed on the surface and which is imparted with a steric design property having a higher grade feeling.

1 . A decorated injection molded article having an embossed pattern, comprising a surface layer comprising an acryl resin film, a printing layer provided on an inside of the surface layer, an adhesive layer provided on an inside of the printing layer and an injected resin layer, wherein a concavo-convex pattern is provided on a surface of the surface layer at a front face part and a side face part of the injection molded article by emboss processing. 
   
   
       2 . The decorated injection molded article having an embossed pattern as described in  claim 1 , wherein the printing layer comprises a colored solid layer. 
   
   
       3 . The decorated injection molded article having an embossed pattern as described in  claim 2 , wherein the printing layer further comprises a picture layer. 
   
   
       4 . The decorated injection molded article having an embossed pattern as described in  claim 1 , wherein the printing layer comprises a light reflective layer. 
   
   
       5 . The decorated injection molded article having an embossed pattern as described in  claim 1 , wherein an angle θ obtained by deducting 90° from an angle formed by a front face part and a side face part of the injection molded article exceeds 0° and is 5° or less. 
   
   
       6 . A method for producing a decorated injection molded article having an embossed pattern, comprising a decorative sheet comprising a surface layer comprising an acryl resin film, a printing layer provided on an inside of the surface layer and an adhesive layer provided on an inside of the printing layer and an injected resin layer formed in an inside of the decorative sheet, comprising:
 a step of subjecting the surface layer of the decorative sheet to emboss processing at a temperature of 150° C. or higher to form a concavo-convex pattern,   a step of vacuum-molding the decorative sheet at a temperature of 90 to 110° C. so that the surface layer faces to an injection molding die side and a step of injecting a resin to the decorative sheet vacuum-molded to form the injected resin layer.   
   
   
       7 . The method for producing a decorated injection molded article having an embossed pattern as described in  claim 6 , wherein the printing layer comprises a colored solid layer. 
   
   
       8 . The method for producing a decorated injection molded article having an embossed pattern as described in  claim 7 , wherein the printing layer further comprises a picture layer. 
   
   
       9 . The method for producing a decorated injection molded article having an embossed pattern as described in  claim 6 , wherein the printing layer comprises a light reflective layer. 
   
   
       10 . The method for producing a decorated injection molded article having an embossed pattern as described in  claim 6 , wherein an angle θ obtained by deducting 90° from an angle formed by a front face part and a side face part of the injection molding die exceeds 0° and is 5° or less.
