Disclosed herein are stretchable conductive ink compositions comprising a polymer, conductive flake, an additive, and optionally conductive beads, wherein the initial resistivity is measured before elongation, and wherein the resistivity at 50% elongation is about 10 times or less of the initial resistivity.

Ultraviolet (UV) absorbing inks and films for surfaces such as glass and/or plastic are provided that include patterns visible to avian eyes, but invisible to a human at least ten feet away. Such invention is aimed at reducing the number of window strikes that result in bird deaths. A formulation may include a binder, a carrier. A formulation may include a base configured to dissolve and solubilize the binder such that it can be applied to the carrier. A formulation may include at least one of an ultraviolet (UV)/visible (VIS) absorbing (UAC) component and a UV/VIS reflective (URC) component.
