A non-ionic surfactant detergent formulation comprising a detergent and additives to improve the properties of the detergent and wherein the detergent comprises a non-ionic surfactant, and the additive comprises a zwitterionic surfactant carrying at least one hydrophobic group having a straight or branched aliphatic chain of 5 to 9 carbon atoms and at least one aliphatic substituent carrying an anionic water-solubilizing group.

Non-ionic surfactant based detergent formulations with short chain

Metal plates, e.g., of magnesium, zinc or copper, suitable for chemical milling and etching operations to produce photoengraving plates, printed circuit boards, nameplates, etc., comprising a metal layer and, adhered thereto, a plastic film layer having a thickness substantially smaller than that of the metal layer. The resulting composite laminates have proved outstandingly useful in permitting the employment of thinner metal layers, thus resulting in lighter weight and less expensive plates, yet retaining the required resistance to the chemical milling or etching process without impairment of mechanical stability and other desirable properties of the plate.
