摘要:
A process for application of metal on a substrate surface comprises applying a mixture of a solvent, a polymerizable monomer, and a photoinitiator on a substrate surface, wherein the photoinitiator does not form two phases together with the monomer and the solvent, i.e. it forms an amorphous mixture without any crystals. The monomer is able to polymerize to a polymer comprising at least one carboxylic group. Thereafter the solvent is evaporated. Polymerization is induced by irradiating the applied dried mixture. Ions are applied and reduced to metal and thereafter further metal can be deposited. The method can be used in industrial processes, both 2D and 3D surfaces can be coated with metal. Materials sensitive to standard grafting chemicals and/or polymers containing halogen atoms can be coated.

A non-aqueous metal catalytic composition includes (a) a complex of silver and an oxime comprising reducible silver ions in an amount of at least 2 weight %, (b) a silver ion photoreducing composition in an amount of at least 1 weight %, and (c) a photocurable component, a non-curable polymer, or a combination of a photocurable component and a non-curable polymer. This non-aqueous metal catalytic composition can be used to form silver metal particles in situ during suitable reducing conditions. The silver metal can be provided in a suitable layer or pattern on a substrate, which can then be subsequently subjected to electroless plating to form electrically-conductive layers or patterns for use in various articles or as touch screen displays in electronic devices.
