SOLUTION COMPOSITION FOR GENERATING VERDIGRIS AND PRODUCTION OF VERDIGRIS COPPER SHEET

摘要

PURPOSE: To securely form a verdigris film high in adhesion properties and hard to peel in a short time and to easily change it into natural verdigris. ;CONSTITUTION: The surface of a coppe sheet is coated with a soln. compsn. for generating verdigris blended in the ratio of 20 to 50 pts.wt. ferric chloride, 100 to 150 pts.wt. ammonium chloride or ammonium carbonate, 50 to 100 pts.wt. copper nitrate, 3 to 10 pts.wt. potassium tartrate and 1000 pts.wt. water and is furthermore coated with a water soluble transparent synthetic resin capable of eluting within one year to produce a verdigris copper sheet.;COPYRIGHT: (C)1996,JPO
