Abstract:
The present invention relates to an improved process for plating plastics using a catalytic filler. More specifically, the present invention relates to electroless plating. According to the present invention objects are created from a material obtained by compounding a granular plastic with a catalyst suitable for an electroless plating reaction. In a subsequent step, removal of the plastic from the surface of step exposes the catalyst. After this the exposed catalyst is activated. Finally the object is plated in an electroless metal bath.

Abstract:
A conductive pattern is prepared in a polymeric layer that has (a) a reactive polymer comprising pendant tertiary alkyl ester groups, (b) a compound that provides an acid upon exposure to radiation having a λmax of at least 150 nm and up to and including 450 nm, and (c) a crosslinking agent. The polymeric layer is patternwise exposed to provide a polymeric layer comprising non-exposed regions and exposed regions comprising a polymer comprising carboxylic acid groups. The exposed regions are contacted with electroless seed metal ions to form a pattern of electroless seed metal ions. The pattern of electroless seed metal ions is then reduced to provide a pattern of corresponding electroless seed metal nuclei. The corresponding electroless seed metal nuclei are then electrolessly plated with a conductive metal.

A method of treating a laser-activated thermoplastic substrate having a metal compound dispersed therein is described. The substrate is contacted with an aqueous composition comprising: (i) a thiol functional organic compound; (ii) an ethoxylated alcohol surfactant; and (iii) xanthan gum. By use of the treatment composition, when the substrate is subsequently laser-activated and plated by electroless plating, extraneous plating of the substrate is substantially eliminated.
