This invention relates to novel compositions comprising a protective polymer layer and a UV blocking agent. This is used in the fabrication of electronic devices using thick film pastes. The present invention is also an electronic device fabrication process using the compositions. The protective polymer layer is fabricated from materials, which are insoluble after irradiation in the ester-type solvents contained in the thick film paste. By appropriate selection of protective film polymers, the protective film can be compatible with the thick film paste and can be further used to shield portions of the thick film paste from UV irradiation.

UV radiation blocking protective layers compatible with thick film pastes

Peptide-based carbon nanotube hair colorants are described. The hair colorants are prepared by coupling hair-binding peptides to the surface of chemically functionalized carbon nanotubes. Hair colorant and cosmetic compositions comprising the peptide-based carbon nanotube colorants are also described.

Peptide-based carbon nanotube hair colorants and their use in hair colorant and cosmetic compositions

The invention provides new hair colorant and cosmetic compositions comprising carbon nanotubes that have either been chemically functionalized or physically modified to increase their affinity for hair.
