Abstract:
A metal-film laminate, resistant to the delamination of the metal from the film, which laminate comprises:(a) a polyimide film layer having at least one surface bearing a non-continuous random distribution of metal-oxide, said metal-oxide selected from the group consisting of oxides of iron, chromium, nickel, molybdenum, manganese, zirconium or mixtures thereof; and(b) a metal surface adhered to the film through the random distribution, said metal surface comprising:(b) a metal surface adhered to the film through the random distribution, said metal surface comprising:(i) a sputtered first metal layer comprising a chromium metal composition having a thickness of about 10 to 100 .ANG.;(ii) a second metal layer, formed on the first metal layer by vapor metallization, having a thickness of about 50 to 5000 .ANG.; and(iii) a third metal layer having a thickness of 0.1 to 40 .mu.m formed on the second layer;wherein the peel strength of the metal-film laminate is at least 3 pounds per inch.
