A first polymer latex and second polymer latex can be mixed to form a dried primer layer on a substrate to adhere patterned materials having fine lines. The first polymer latex comprises a first polymer and a first surfactant such that a dried coating of the first polymer latex has a surface polarity of at least 50%. The second polymer latex comprises a second polymer and a second surfactant such that a dried coating of the second polymer latex has a surface polarity of less than or equal to 27%. Moreover, a dried coating of the mixture has a surface polarity of at least 15% and up to and including 50%. Primed substrates are useful for preparing electrically-conductive articles having electrically-conductive fine lines directly on a dried primer layer by applying a patterned material to a substrate. Such articles can be used as touch screen displays in various electronic devices.

Articles can be formed with either a dried layer or a dried pattern of a non-aqueous photocurable composition on one or both sides of a substrate. This composition includes 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. The dispersed carbon-coated metal particles have a median diameter of less than 0.6 &#x3bc;m, and a particle dispersing agent that has a weight average molecular weight (M) of at least 2,000 and up to and including 10,000 and comprises nitrogen-containing units, the median diameter being determined using a dynamic light scattering method. Such articles can be used for various purposes including the formation of electrically-conductive grids, and can be incorporated into various devices including those having touch screen displays.

A method is used to provide a pattern of a functional material for example on a receiving element.
