Abstract
A printable composition for forming an insulating layer is disclosed, the insulating layer typically being a dielectric layer. The printable composition is particularly well suited for making cured insulating layers on touch screens, but is also suitable for a variety of other applications. In certain embodiments the composition is suitable for application using digital printing technology such as ink jet printing to precisely apply the printable composition it to a substrate. In addition, the present invention is directed to insulating layers and made using the composition, as well as to methods of applying the composition and articles incorporating insulating layers made using the composition.
