Claim:
1. An article comprising a substrate and having on one or both supporting sides of the substrate, either a dried layer or a dried pattern of a non-aqueous photocurable composition that comprises a photocurable component and dispersed carbon-coated metal particles present in an amount of at least 10 weight % based on the total weight of the non-aqueous photocurable composition, and a particle dispersing agent that has a weight average molecular weight (M w ) of at least 2,000 and up to and including 100,000 and comprises nitrogen-containing units, the median diameter being determined using a dynamic light scattering method, wherein: the dispersed carbon-coated metal particles are dispersed carbon-coated silver particles or dispersed carbon-coated copper particles, or a mixture of both dispersed carbon-coated silver particles and dispersed carbon-coated copper particles, and when the dispersed carbon-coated metal particles are dispersed at 50 weight % in 1-methoxy-2-propanol at a 20:1 weight ratio of the dispersed carbon-coated metal particles to the particle dispersing agent, the median diameter of the dispersed carbon-coated metal particles is less than 0.25 μm, the median diameter being determined using a dynamic light scattering method.
