Abstract

This invention relates to a process for forming a pattern using a photosensitive composition comprising a polymeric azide and a high-molecular weight copolymer or polymer. The photosensitive composition comprises a copolymer containing at least a water-soluble non-photosensitive monomeric unit having an electrolytic functional group, a monomeric unit having an azido group and an electrolytic functional group and a high-soluble high molecular weight copolymer or polymer which exhibits reciprocity law failure characteristic.
