20170145245 · 2017-05-25 · ·

The present invention provides an economical route to environmentally friendly polymeric coatings with a high content of raw materials from renewable resources. These polymeric coatings offer performance characteristics that are competitive with conventional coating systems. The unique polymers on which this invention is based are copolymers of triglyceride oils, such as soybean oil, linseed oil, or another natural oil, with a vinyl compound, such as an acrylate or methacrylate, or a vinyl aromatic monomer. The present invention more specifically discloses a water dispersible, self-crosslinkable prepolymer composition which is comprised of a triglyceride oil having appended thereto (1) hydroxyl groups, (2) epoxy groups, (3) moieties which contain at least one aldehyde group or at least one ketone group, and (4) moieties which contain at least one vinyl and/or substituted vinyl group. In one embodiment of this invention the moiety which contains at least one vinyl group is derived from maleic anhydride.

ELECTRONIC DEVICES AND PRECURSOR ARTICLES

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.
