A non-aqueous photocurable composition contains dispersed carbon-coated metal particles in an organic diluent in an amount of at least 10 weight %. The dispersed carbon-coated metal particles have a median diameter equal to or less than 0.6 μm, and are dispersed using a particle dispersing agent that has a weight average molecular weight (Mw) of at least 2,000 and up to and including 100,000 and comprises nitrogen-containing units. The median diameter of the dispersed particles is determined using a dynamic light scattering method. Moreover, when the non-aqueous composition contains up to and including 25 weight % of the dispersed carbon-coated metal particles, it exhibits no visual settling when subjected to a settling test of at least 24 hours at 20° C. Such non-aqueous photocurable compositions include photocurable components and are useful to prepare photocurable and photocured electrically-conductive patterns and layers in various articles, including touch screen devices having touch screen displays.
