Abstract:
A process for direct metal-plating of a plastic substrate (14). The process comprises the steps of: (i) activating a surface of modified polyolefin substrate to produce an active surface (16), the active surface (16) having at least about 7 % of carbon atoms in the form of carbonyl; (ii) electrochemically depositing metal layer (18) on the active surface (16).
Abstract:
A member having a metallic layer which exhibits an enhanced adhesion between a resin base and a precipitated metal because of chemical interaction without roughening the surface of the resin base, a method for manufacturing the same, a build-up multilayer wiring board using the member, a flexible wiring board, and a wiring board for multi-chip modules all those board being excellent and using the member are disclosed. The member is characterized by comprising a resin base of a resin composition containing an aromatic amide site in its chemical structure, a metallic fine particle layer formed on the resin base, a metal oxide layer formed on the metallic fine particle layer, and a metallic layer formed on the metal oxide layer. The metallic fine particle layer is a catalysis layer, an electroless plating layer is formed on the metallic fine particle layer, and the metallic layer, which is an electroplating layer, is formed on the electroless plating layer, and thus the wiring is set up. By the formation of fine wiring, a build-up multilayer wiring board, a flexible wiring board, and a wiring board for multi-chip modules all excellent in reliability are provided.

Abstract:
Process for the direct metallizing of the surface of a plastic object. The surface of the plastic object is roughened by pickling. The surface is activated with the aid of a colloidal or ionogenic aqueous solution of a first precious metal, which colloidal or ionogenic aqueous solution also contains a second base metal. This forms an activation coat on the surface containing the first precious and the second base metal. Electron conductivity of the activation coat is provided with the aid of a treatment solution, with which the second base metal is at least partially dissolved out of the activation coat and an electron conducting substance is adsorbed in the activation coat. Then the electron-conductive activation coat is metallized. Before the electron conducting activation coat is metallized, the sequence of steps "activation of the surface and establishment of electronic conductivity" is repeated at least once.
Abstract:
Applications of a metallized textile. The textile is activated by precipitating noble metal nucleation sites on the fibers of the textile. Immersing the activated textile in a suitable prepared solution of a metal cation, and adding a reducing agent, leads to the formation of a metal plating tightly and intimately bonded to the fibers of the textile. Exposure of the metallized textile to air oxidizes the surface of the metal plating. Applications of the metallized textile include acaricides, fungicides, bactericides, armor, electrodes, anti-static devices, RF shielding, and radar reflectors.

A process for activating a textile to catalyze the reduction of a metal cation, a process for metallizing the activated textile with the reduced metal, and the activated textile and metallized textile thereby produced. The textile is activated by precipitating noble metal nucleation sites on the fibers of the textile. Immersing the activated textile in a suitably prepared solution of a metal cation, and adding a reducing agent, leads to the formation of a metal plating tightly and intimately bonded to the fibers of the textile.

Abstract:
In order to sensitize the surface of an insulating substrate with a view to subsequent electroless metallization, powder particles are transferred to the surface by means of a xerographic process. The particles carry the sensitizing compound, at least on their surface. After fixing of the transferred powder, conventional electroless metallization may take place. The xerographic transfer enables selective plating, since any master that might be copied by the xerographic process may also be transferred to the surface of the substrate. The powder used with the process may be manufactured by acting on an existing plastic powder by a sensitizing metal compound in an organic solution having at least a superficial influence on the individual powder particles.
Abstract:
Beschrieben wird ein Verfahren zur Bereitstellung einer Oberfläche mit metallischer Optik auf einem Substrat, wobei zur Herstellung der Oberfläche auf das Substrat eine Primerschichtaufgebracht wird, zwecks Bildung einer Silberschicht eine Silbersalzlösung mit einem Reduktionsmittel gemischt und auf die Primerschicht aufgesprüht wird, und auf die Silberschicht eine transparente oder transluzente Decklackschichtaufgebrachtwird. Die Primerschicht wird auseiner hydroxyfunktionellen Komponente und einem isocyanatfunktionellen Härter gebildet. Als isocyanatfunktioneller Härter wird Isophorondiisocyanat (IPDI) verwendet. Weiterhin werden ein gemäß dem Verfahren hergestelltes Schichtsystem und ein Substrat mit einem solchen Schichtsystem beschrieben.
