Provided is a production method that enables production of carbonyl sulfide by a gas phase flow method without using a catalyst. The method of producing carbonyl sulfide includes causing electrical discharge of a feedstock gas containing starting substances that include CS.sub.2 and one or more selected from the group consisting of CO.sub.2, CO, O.sub.2, and O.sub.3 while in a continuous flow state and then causing release to outside of an electrical discharge zone.

Provided are a novel water-soluble diacetylene monomer, a composition for photolithography including the novel water-soluble diacetylene monomer and a conductive polymer, and a method of forming micropatterns using the composition. The water-soluble diacetylene monomer may not aggregate even when mixed with a water-soluble conductive polymer. Accordingly, a uniform composition for photolithography can be prepared by mixing a water-soluble conductive polymer with the diacetylene monomer, and micropatterns can be formed using the composition. More particularly, when the composition is formed into a thin film and then is irradiated with light, only light-irradiated portions of the diacetylene monomer are selectively crosslinked due to photopolymerization, thereby resulting in insoluble negative-type micropatterns.
