The present invention relates to weather-resistant pearlescent pigment, comprisinga coated or uncoated platelet-shaped substrate which is selected from the group consisting of synthetic mica platelets, glass platelets, SiO2 platelets, Al2O3 platelets, synthetic boehmite platelets, BiOCl platelets and mixtures thereof, a chromophoric coating with at least one highly refractive metal oxide, and a top layer, wherein the top layer comprises the following layer sequence: a) a first layer made of tin oxide and/or tin hydroxide and/or hydrated tin oxide, b) a second cerium-containing layer which comprises cerium oxide and/or cerium hydroxide and/or hydrated cerium oxide, c) an organic-chemical coating applied to the cerium-containing layer which contains oligomeric silanes or consists of them, wherein the oligomeric silanes have one or more amino groups and the oligomeric silanes are chemically bonded with the cerium-containing layer. The invention further relates to a process for the production and use of these pearlescent pigments.
