Abstract: The invention relates polysilazane-containing coatings for increasing the light permeability of sun-facing covers of solar cells. The coating for surfaces contains at least one polysilazane of formula (1) —(SiRR?R?—NR??1)n— (1), wherein R?,R?,R?? are the same or different or represent an optionally substituted alkyl, aryl, vinyl or (trialkoxysilyl)alkyl group, n being an integer and n being chosen in such a manner that the perhydropolysilazane has a number average molecular weight of 150 to 150,000 g/mol, a solvent and a catalyst. The cured coating has a thickness of at least 0.50-10 micrometer, preferably 0.2 to 5 micrometer, especially preferred 0.5 to 1.5 micrometer. It is especially suitable as transmission-promoting coating for use in sun-facing covers of solar cells.

Abstract: The invention relates to the use of a pigment preparation as a dye for producing a colored optical image in an electronic display, said pigment preparation containing (A) at least one organic and/or inorganic pigment, (B) at least one solvent-soluble or solvent-dispersible polymeric dispersant, (C) at least one aldehyde resin or ketone resin, (D) optionally further additives common for producing solvent-containing pigment preparations, and (E) at least one hydrophobic solvent.
