  • Patent number: 10174425
    Abstract: A non-aqueous stannous alkoxide composition comprises: component (a) comprising a water-insoluble stannous alkoxide complex comprising stannous ions in an amount of at least 1 weight %, and a photocurable component (b), non-photocurable water-insoluble polymer component (c) having a molecular weight of at least 10,000, or both the photocurable component (b) and the non-photocurable water-insoluble polymer component (c). When photocurable component (b) is present, the non-aqueous stannous alkoxide composition further comprises photosensitizer component (d) that is different from all of components (a) through (c), in an amount of at least 1 weight %. These compositions can be used to prepare silver particles as “seed” catalysts in various articles that can then be used for other purposes such as electroless plating.
