(I) pref. is an aromatic sulphonic acid, esp. PhSO3H, which pref. is used as a 15% soln. in DMF. The soln. is suitable for the rapid and complete removal of these coatings from steel, iron, light and non-ferrous metals, without attacking their surfaces. It is free from phenol and does not lead to water pollution.
