The present invention relates to a chrome free etch for plating on plastic processes, wherein plastic surfaces are contacted in a first etching step with an etching solution at least comprising Mn(IV)-ions and, in a second etching step, with a solution at least comprising Mn(III)- and Mn(VII)-ions prior to the metal plating step.

A method of producing a film-attached resin base may include supplying a surface treatment gas including at least fluorine gas to a resin base including reinforcing fibers so that embrittled regions are formed in a surface of the resin base and the reinforcing fiber present near the surface of the resin base is modified at least partially; removing at least the embrittled regions so that an uneven surface is formed on the resin base and the reinforcing fiber is at least partially exposed in the uneven surface; and forming a film onto the uneven surface of the resin base.

A laminate comprising a substrate; and a plating-forming layer disposed on at least one surface of both surfaces of the substrate and containing a thermoplastic resin and a plating catalyst, wherein the plating-forming layer further satisfies conditions of the following (1) and/or (2),

(1) the plating-forming layer contains a dispersing agent for dispersing the plating catalyst
(2) an abundance of the plating catalyst on a surface side of the plating-forming layer is higher than an abundance of the plating catalyst on the substrate side of the plating-forming layer.

A method for producing metal patterns, which includes depositing a temporary protection on a substrate surface corresponding to the negative of the patterns to be produced; depositing at least one metal on the areas corresponding to the patterns to be produced; and eliminating the temporary protection at least partly during and/or after, or at least partly during and/or after the deposition step. The method can produce decorative objects or functional objects such as printed circuits, integrated circuits, RFID chips, and electronic reader-readable encoding pictograms. A set of consumables used to implement the method is also disclosed.
