Abstract: A method for producing infra-red inert substrates, including moulded 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 colourant. 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.
