Abstract: 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.

Preferably, said charged particle comprises a dye attached to said inorganic core and said counter ion comprises a (poly)siloxane moiety linked via suitable bridge members to a quaternary, positively charged, nitrogen or phosphorus atom, or to a moiety carrying an anionic functional group. Said composition may be used e.g. in the form of a homogenous dispersion in an electrophoretic display.
