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 - 9  (cancelled)  
     
     
         10 . An assembly of a mold for making a substrate for a plasma display panel comprising a base and ribs, said mold having concave portions, and a rib precursor for forming said ribs said rib precursor being disposed in said concave portions of said mold and containing a first photo-setting initiator having a first absorption edge and a first photo-setting component, said mold being obtained by photo-setting a second photo-setting component in the presence of a second photo-setting initiator having an absorption edge whose wavelength is shorter than a wavelength corresponding to said first absorption edge of said first photo-setting initiator.  
     
     
         11 . The assembly according to  claim 10 , wherein said mold is flexible.  
     
     
         12 . The assembly according to  claim 11 , wherein said mold is transparent.
