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.
