Patterned and primed transparent articles

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.

主权项

1. An article comprising a transparent polymeric substrate comprising: a transparent support and a dried primer layer disposed on at least one supporting surface of the transparent support, and a patterned material comprising lines having an average line width of less than 15 μm, which patterned material is disposed directly on the dried primer layer,
wherein the dried primer layer comprises a mixture of: a first polymer latex comprising 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%, and a second polymer latex comprising 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%, and the dried primer layer has a surface polarity of at least 15% and up to and including 50%.
