In a process for forming a nanoparticulate crystalline titanium phthalocyanine pigment composition, a titanium phthalocyanine pigment is contacted with substantially pure 1,1,2-trichloroethane under conditions effective to convert the titanium phthalocyanine pigment to the nanoparticulate crystalline composition. The method for producing a molded body having microstructures on a carrier out of molding material is effected by inputting a molding material into a container comprising a mold cavity, wherein at least one micro-structured mold is provided in the mold cavity. A floating gate opposing the channel region and is separated therefrom by a gate oxide.
