Method of producing substrate for plasma display panel and mold used in the method

Abstract

A method of producing a substrate for a plasma display panel by providing a rib on a base, which comprises the steps of contacting a rib precursor containing a first photo-setting initiator having a first absorption edge and a first photo-setting component closely with said base; filling a mold, obtained by photo-setting of a second photo-setting initiator having a second absorption edge whose wavelength is shorter than a wavelength corresponding to said first absorption edge of said first photo-setting initiator, with said rib precursor; exposing said rib precursor to light having a wavelength longer than a wavelength corresponding to said second absorption edge, thereby setting said rib precursor; and removing said mold.

1 . A method of producing a substrate for a plasma display panel comprising: 
 contacting a rib precursor containing a first photo-setting initiator and a first photo-setting component closely with a base;    filling a mold with said rib precursor, the mold obtained by photo-setting of a second photo-setting initiator and a second photo-setting component by exposure to ultraviolet light;    exposing said rib precursor to light using a fluorescent lamp; and    removing said mold.    
   
   
       2 . The method according to  claim 1 , wherein the base and mold are transparent and exposure of the rib precursor to light is conducted via the base and mold.  
   
   
       3 . The method according to  claim 1 , wherein the mold is flexible.  
   
   
       4 . The method according to  claim 1 , wherein the first photo-selling initiator has the first absorption edge corresponding to a wavelength of 400 to 500 nm and the second photo-setting initiator has the second absorption edge corresponding to a wavelength of 300 to 400 nm.  
   
   
       5 . The method according to  claim 1 , wherein the first photo-setting component and second photo-setting component are acrylic resin.  
   
   
       6 . The method according to  claim 1 , wherein the rib precursor contains a powder of ceramic and optionally contains a powder of glass.  
   
   
       7 . A method of producing a substrate for a plasma display panel comprising: 
 filling a mold, obtained by photo-setting of a second photo-setting initiator and a second photo-setting component by exposure to ultraviolet light;    contacting a rib precursor containing a first photo-setting initiator and a first photo-setting component closely with a base,    exposing the rib precursor to light using a fluorescent lamp; and    removing said mold.    
   
   
       8 . The method according to  claim 7 , wherein the base and mold are transparent and exposure of the rib precursor to light is conducted via the base and mold.  
   
   
       9 . The method according to  claim 7 , wherein the mold is flexible.  
   
   
       10 . The method according to  claim 7 , wherein the first photo-setting initiator has the first absorption edge corresponding to a wavelength of 400 to 500 nm and the second photo-setting initiator has the second absorption edge corresponding to a wavelength of 300 to 400 nm.  
   
   
       11 . The method according to  claim 8 , wherein the first photo-setting component and second photo-setting component are acrylic resin.  
   
   
       12 . The method according to  claim 7 , wherein the rib precursor contains a powder of ceramic and optionally contains a powder of glass.
