Abstract: Functionalized nanoparticles, which are obtainable by combining in a first step a functionalized dyestuff, a silicon-based spacer and a catalyst, and in a second step reacting the product obtained in the first step with a co-reactive organic silicon, aluminum, zirconium or titanium compound. Optionally, the thus obtained functionalized nanoparticles can be combined or encapsulated with a polymer. The functionalized nanoparticles are useful as colorants and fluorescents in plastics, paints, inks, electronic materials, cosmetic articles, and the like.

Abstract: The present invention relates to a photochromic ink, the process for its preparation which is based on a spiropyran powder obtainable by melting, cooling and crushing, and to a new form of a spiropyran obtainable thereby. Said process to prepare a photochromic ink comprises the steps of a) heating and melting the spiropyran at a temperature below 250 C, b) cooling the melt to obtain a solidified spiropyran, c) crushing the solidified spiropyran to obtain a powder, d) optionally adding the powder to a binder providing the basis for the photochromic ink.
