| abstract | The steel agent of the present invention is an acidic aqueous solution containing ferrous ions, ferric ions and acetylene group-containing water-soluble compounds. It is preferable that the value of A / B is 0.1 to 2.5 when the concentration of ferrous ion in the etching agent is A weight% and the concentration of ferric ion is B weight%. The replenisher of the present invention is an aqueous solution containing an acetylene group-containing water-soluble compound as a replenisher to be added to the etchant when the etchant is used continuously or repeatedly. |
