PURPOSE: An etching paste composition for a conductive polymer membrane is provided to have an excellent etching capacity for the conductive polymer membrane and to shorten a process. CONSTITUTION: An etching paste composition for a conductive polymer membrane comprises halogen compound and water-soluble binder, and 0.5-8 weight% of halogen compound is included based on the total weight of the composition. The halogen compound is selected from sodium hypochlorite, sodium hypobromite, NaIO, and mixture of them. 20-99.5 weight% of water-soluble binder is included based on the total weight of the composition, and includes urethane group, polyvinylacetate group, cellulose group, and mixture from selected resin and solvent. |
