Abstract: The present invention pertains to a coating composition for the coating of a substrate such as a mirror or a glass. The invention is characterized in that the coating composition comprises a polyalkylsiloxane with terminal hydroxyl groups or a mixture of different polyalkylsiloxanes with terminal hydroxyl groups, silicon tetrahalide or alkyl halogen silane or mixtures thereof, and an inert aprotic.

Abstract: This invention relates to lead free and cadmium free copper-containing glass frits that can be used as pigments to color other glass frits or to impart color to solid substrates such as glass, ceramic or metals, or to impart color to a thermoplastic mass. The compositions comprise silica, alkali metal oxides, alkaline earth metal oxides, tin oxide and copper oxide. The resulting compositions can be used to decorate and protect automotive, beverage, architectural, pharmaceutical and other glass substrates, generally imparting a red color.

Abstract: The grayish-black encapsulated pigments contain carbon black particles with specific surface areas of 10 to 1000 m.sup.2 /g (BET) encapsulated in colorless crystals of zirconium silicate. In order to produce the pigments, mixtures of zirconium oxide with a particle size distribution (D50 values) between 7 and 10 .mu.m and a spec. surface between 2 and 4 m.sup.2 /g, silicon oxide, carbon black and mineralizers are heated under reducing conditions to 900.degree. to 1400.degree. C. and calcined for 0.5 to 8 hours and recalcined under oxidizing conditions to remove the non-included carbon black. The encapsulated pigments of the invention are suitable for the pigmented coloration of glazes.

Abstract: Encapsulation pigments comprising chromophoric particles embedded in glaze-stable casings are prepared by means of calcination from the appropriate initial products. High yields and strong color intensities are obtained if the chromophoric substance or its initial compounds are bound in and/or to a zeolite and are calcined in this form with the remaining constituents.
