ABSTRACT:
A process for the production of a corrosion resistant metallic article having a matt nacreous appearance and the resultant article. The process comprises the steps of coating a metallic substrate with a clear paint comprising a curable resin vehicle and a flaky nacreous pigment having a colorless transparent appearance selected from oxides and salts of elements of Groups IV and V of the Periodic Table, to form on the metallic substrate a clear paint coating having a finely undulated surface in which the nacreous pigment is arranged in a non-laurellate fashion, and then curing the paint coating on the metallic substrate to produce the metallic article. The metallic substrate is preferably zinc or zonc alloy which is chemically treated to form a colorless, transparent corrosion-resistant film thereon prior to coating with the clear paint.
