A method for producing infra-red inert substrates, including molded polymeric articles, films, fibers and coatings and other organic and inorganic materials, by incorporating into the substrate or onto the surface of the substrate an effective amount of a dispersed bis-oxodihydroindolylen-benzodifuranone colorant. The thus obtained, also claimed substrates so produced are reflective and transparent to much of the near infra red radiation not reflected. There are multiple applications for cases of devices comprising electronic components, outdoor construction elements, outdoor furniture, automotive, marine or aerospace parts, laminates, artificial leather or textile materials, as well as in polychrome printing processes and optical fibers. The thus obtained substrates can also be subjected to laser welding. New bis-oxo-dihydroindolylen-benzodifuranone compounds are also claimed.

Described herein are molecular inks, methods for printing the molecular inks on flexible substrates, and methods for forming printed electronic elements, such as resistive heaters, force sensors, motion sensors, and devices that include these elements, such as force responsive conductive heaters. The methods include printing a molecular ink on a flexible substrate that is heated to 30° C. to 90° C. before and/or during the printing process and curing the substrate to produce a conductive pattern thereon. The molecular inks generally include a particle-fee metal-complex composition formulated from at least one metal complex and a solvent, and optionally, a conductive filler material, and/or surfactant.
