(57) ABSTRACT

Provided are aerosol jet uncoated and coated (e.g., glass coated) metal conductive ink compositions that can be depos ited onto a substrate using, for example, aerosol jet printing and direct-Write methods such as Aerosol Jet (e. g., Optomec M 3 D) deposition and methods of aerosol jet deposition of the aerosol jet uncoated and coated metal conductive ink compo sitions. Also provided are aerosol jet UV curable dielectric ink compositions that exhibit transparency, storage stability, and very good print quality and print stability, thereby enabling the formation of very ?ne dielectric features on a variety of substrates.
