PURPOSE: To obtain a chemical solution for artificial verdigris for forming a verdigris coating film having adhesivity and free from discoloring by preparing the chemical solution consisting of a specified ratio of ZnCl2, H3PO4, H2O2 and water and having a specific pH value. ;CONSTITUTION: The chemical solution consisting of 10-200g/l ZnCl2 50-500g/l H3PO4, 20-100g/l H2O2 and balance water and having pH of -1 to 2 is prepared. If necessary, at least one of ≤50g/l NaOH, 50g/l Zn, ≤10g/l one or more kind of SnCl2, CoCl2, NiCl2 and ethylenediaminetetraacetic acid is added. The artificial verdigris coating film excellent in workability and weather resistance is obtained by sticking the chemical solution to a copper alloy by ≥20g/m2 dry coating weight and aging it in the atmosphere of 20-80°C and ≥60% humidity.;COPYRIGHT: (C)1996,JPO
