Process for production of pattern-forming body

Abstract

A primary object of the present invention is to provide a process for the production of a pattern-forming body, the process enabling the formation of a highly precise pattern, requiring no post-exposure treatment and being free from a fear as to the deterioration of the pattern-forming body itself because no photocatalyst is contained in the produced pattern-forming body. In the present invention, the above problem can be solved by providing a process for the production of a pattern-forming body, the process comprising disposing a catalyst-containing layer-side substrate containing at least a photocatalyst-containing layer and a pattern-forming body substrate containing a characteristic-changeable layer which is changed in characteristics by the action of the photocatalyst in at least said photocatalyst-containing layer such that the photocatalyst-containing layer is in contact with the characteristic-changeable layer, followed by performing exposure to thereby change the characteristics of the exposed portion of the characteristic-changeable layer and thereafter dismounting the photocatalyst-containing layer-side substrate, thereby obtaining a pattern-forming body having a pattern which has been changed in characteristics on the characteristic-changeable layer.

1 . A functional element comprising a decomposition-removable layer and a functional portion, 
 wherein the decomposition-removable layer is a layer decomposed and removed by an action of a photocatalyst and excluding a photocatalyst-containing layer; and    the functional portion is disposed on a section corresponding to a pattern formed on a pattern-forming body having the pattern with the decomposition-removable layer decomposed and removed.    
   
   
       2 . The functional element according to  claim 1 , wherein the decomposition-removable layer is different in contact angle with water from an exposed member which is exposed when the decomposition-removable layer is decomposed and removed.  
   
   
       3 . The functional element according to  claim 1 , wherein contact angle of the decomposition-removable layer with water is 60 degrees or more and the contact angle of an exposed member which is exposed when the decomposition-removable layer is decomposed and removed is 30 degrees or less.  
   
   
       4 . The functional element according to  claim 1 , wherein the decomposition-removable layer comprises a hydrocarbon type, fluorine type or silicone type nonionic surfactant.  
   
   
       5 . The functional element according to  claim 1 , wherein the functional portion is a metal.  
   
   
       6 . The functional element according to  claim 1 , wherein the functional portion is formed on an exposed member which is exposed when the decomposition-removable layer is decomposed and removed.  
   
   
       7 . A color filter comprising a pixel portion, wherein the pixel portion is the functional portion of the functional element as claimed in  claim 6 .  
   
   
       8 . A microlens comprising a lens, wherein the lens is the functional portion of the functional element as claimed in  claim 6.
