The present invention relates to a toner and process for preparing a toner for reproduction of a metallic, preferably golden or silvery, hue by a printing process, especially for electrophotography. The fitting assembly is located in a respective aperture in the tub wall. These improvements increase the speed at which such commands are executed and completed, and increase the capabilities of copy managers in serverless backup systems. The transducer further includes a plurality of electrodes defined on the first surface, the electrodes having boundaries configured so that none of the exposed faces are in contact with more than one of the plurality of electrodes. The process comprises mixing a silicon component which comprises, at least one hydrolyzable silicon compound having a non-hydrolyzable polymerizable group, with water to form a hydrolysis product, and 15 s to 15 min after mixing with water, the addition of, at least one compound of boron or a metal selected from Al, Ga, In, Tl, Ge, Ga, Sn, Pb, Ti, Zr, Hf, Sc, Y and La.
