Electronic devices and precursor 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. A method for providing a plurality of precursor articles, the method comprising:
providing a continuous web of a transparent polymeric substrate that comprises a transparent polymer support and a dried primer layer disposed directly on at least one supporting surface of the transparent polymer support, the dried primer layer comprising 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%, anda second polymer latex comprising a second polymer and a second surfactant that is different from the first surfactant such that a dried coating of the second polymer has a surface polarity less than or equal to 27%,wherein the dried primer layer has a surface polarity of at least 15% and up to and including 50%, forming a first curable pattern directly on the dried primer layer in a first portion of the continuous web, the first curable pattern comprising a photocurable or thermally curable composition comprising seed metal particles, by direct contact of the dried primer layer in the first portion of the continuous web with a flexographic printing member carrying the photocurable or thermally composition, advancing the continuous web comprising the first portion comprising the first curable pattern to be proximate a curing station and curing the first curable pattern, thereby forming a first cured pattern on the first portion, which first cured pattern comprises the seed metal particles, forming a second curable pattern directly on the dried primer layer in a second portion of the continuous web, the second curable pattern comprising the same or different photocurable or thermally curable composition comprising the same or different seed metal particles, by direct contact with a flexographic printing member carrying the same or different photocurable or thermally curable composition, advancing the continuous web comprising the second portion comprising the second curable pattern to be proximate a curing station and curing the second curable pattern, thereby forming a second cured pattern on the second portion, which second cured pattern comprises the same or different seed metal particles, optionally, carrying out the forming and advancing features one or more times for additional respective portions of the continuous web using the same or different curable or thermally curable composition and the same or different flexographic printing member to form additional cured patterns on the additional respective portions, and winding up the continuous web comprising first, second, and optional additional cured patterns to provide a roll of a plurality of precursor articles.
