The present invention relates to surface-functionalized titanium dioxide nanoparticles, a process for their production, a coating composition, comprising surface-functionalized titanium dioxide nanoparticles and the use of the coating composition for coating holograms, waveguides and solar panels. The holograms are bright and visible from any angle, when printed with the coating composition, including the surface-functionalized titanium dioxide nanoparticles. |
