Latex primer composition and latex primed substrates

摘要

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.
