    摘要： The present invention relates to a process for producing coated bismuth vanadate yellow pigments comprising the following steps: (a) subjecting a reaction mixture comprising a suspension in nitric acid of bismuthyl nitrate and vanadium (V) oxide, or a suspension in nitric acid of bismuth (III) oxide and vanadium (V) oxide, to stirring to form bismuth vanadate particles; (b) terminating the stirring and holding the reaction mixture for a period of time; (c) filtering off the bismuth vanadate particles; (d) washing the bismuth vanadate particles; (e) dispersing the washed bismuth vanadate particles in a hot, phosphate-containing, aqueous solution to activate the surface of the particles; (f) filtering off the activated bismuth vanadate particles; (g) washing the activated bismuth vanadate particles; (h) dispersing the activated bismuth vanadate particles in water to form a suspension; (i) precipitating at least one material selected from the group consisting of hydrated aluminum phosphate, aluminum/zinc phosphate or silicon oxide onto the external surface of the activated bismuth vanadate particles in the suspension to form said coating; (j) filtering off the coated bismuth particles; (k) washing and drying the coated bismuth vanadate particles.

    摘要： The present invention relates to a method for producing a composition comprising polythiophene, comprising the method steps: I) provision of a composition Z1 comprising thiophene monomers and an oxidising agent; II) oxidative polymerisation of the thiophene monomers by reducing the oxidising agent to a reduction product and oxidation of the thiophene monomer, forming a composition Z2 comprising a polythiophene and the reduction product; III) at least partial removal of the reduction product from the composition Z2 obtained in method step II), obtaining a composition Z3; wherein the composition Z3 has a sulfate content in the range from 100 ppm to 1,000 ppm, based on the total weight of the composition Z3. The present invention also relates to a composition obtainable as the composition Z3 produced with this method, a composition comprising a polythiophene, a layer construction, an electronic component and the use of a composition.
