Wet etchant composition |
| abstract |
A wet etching agent composition for a transparent conductive film, which is an aqueous solution containing oxalic acid and polyoxyethylene alkyl ether sulfate and / or polyoxyethylene alkylphenyl ether sulfate. It is possible to provide a wet etching agent which does not generate any etching residue when performing wet etching of amorphous ITO using an oxalic acid aqueous solution and can perform etching under mild conditions. |
