high opacity titanium dioxide pigment and process for its preparation. The present invention relates to a rutile titanium dioxide pigment for use in high-opacity decorating papers in the light of the state of the art, as well as a process for the preparation. The pigment has a surface coating containing aluminum phosphate, aluminum oxide, silicon oxide and titanium oxide, however, it does not contain any significant amounts of a zirconium compound. silicon oxide is present in loose deposition, the specific surface, according to bet, matters at least 15 m2 / g. The preparation process is characterized by the fact that, firstly, an aluminum component and a phosphorus component are added to a thio2 suspension. The next step is the addition of an alkaline silicon component and an acid-reacting titanium component and optimally another ph-value regulating component, where the ph value is set to a value in the range of 4 to 9.
