ABSTRACT:
Disclosed are a photosensitive composition comprising a copolymer comprising acrylamide, diacetone-acrylamide and a sulfonated vinyl monomer, such as sodium p-styrenesulfonate, and a water-soluble aromatic bisazide compound, and a pattern-forming method using this photosensitive composition.
This photosensitive composition has a reciprocity law failure, and when this photosensitive composition is used, the development after light exposure is completed in a short time.
