  • Publication number: 20220064466
    Abstract: The present invention relates to flexible and stretchable UV and thermally curable dielectric ink compositions that can be thermo or vacuum formed. The flexible ink can form a stretchable dielectric coating having excellent adhesion. The dielectric ink compositions can be applied on a circuit board, such as a paper-phenolic resin board, plastic board (PMMA, PET or the like) or a glass-epoxy resin board, by screen printing or the like, followed by heat/UV curing. The compositions are suitable for use in applications such as a capacitive touch, in-mold forming, creating cross over insulation layers, and manufacturing electronic circuity and devices.
