    • The invention relates to weather-resistant pearlescent pigments which have improved application properties and are based on a small glass plate that is coated with highly refractive metal oxides and a protective coating located on the top metal oxide layer. The inventive pigments are characterized in that the small glass plate has an average thickness of 50 to 500 nm. According to variant A, a metal oxide layer whose refractive index n exceeds 1.8 and which comprises TiO 2 having a rutile concentration ranging from 80 to 100 percent by weight as well as a protective SiO 2 coating are applied. According to variant B, a metal oxide layer whose refractive index n exceeds 1.8 and which comprises TiO 2 having a rutile concentration ranging from 80 to 100 percent by weight as well as a protective coating containing a first protective layer with cerium oxide and/or cerium oxide hydrate and/or cerium hydroxide and a second protective SiO 2 layer are applied. Additionally, an organic chemical surface coating is applied to the metal oxide layer of the protective coating of A or B. The invention further relates to a method for producing said pigments and the use thereof.

    • The invention relates to a pearlescent pigment comprising a metal-oxide containing, lamellar substrate comprising a first and a second protective layer, the metal oxide layer having a refractive index of more than 1,8. The first protective layer comprises cerium oxide and/or cerium hydrate and/or cerium hydroxide, the secodn protective layer is made, essentailly, preferably completely of SiO 2 . The second protective layer is arranged downstream from the first protective layer and between the first and the second protective layers, metal oxide layers, which are different from cerium oxide and/or cerium hydrate and/or cerium hydroxide and SiO 2 can be arranged. The second protective layer comprises an organic-chemical secondary coating which comprises at least one a-silane of formula (I): -O (4-n-m) -Si(-R 1 ) m (-CH 2 -Y) n , which is bound to the second protective layer by means of at least one oyxgen atom, wherein 1 = n+m = 3; m = 0 - 2; n = 1 - 3 ist and R 1 represents a hydrogen atom or a Si-C bound C 1 -C 20 -hydrocarbon radical or a C 1 -C 15 -hydrocarbon radical, wherein, respectively, one or more non-adjacent methylene units by have been replaced by groups -O-, -CO-, -COO-, -OCO-, or -OCOO-, -S-, or -NR X - and in which one or more non-adjacent methine units may have been replaced by groups -N=, -N=N-, oder -P=, wherein R 1 can be identical or different, identical or different, R x can be a hydrogen atom or a linearer, branched and/or cyclic C 1 -C 15 - carbon, hydrogen or aryl radical, and Y is a reactive functional binding group comprising a binding agent system.
