    Abstract: Interference pigments based on multiply coated plateletlike silicatic substrates comprising A) a first layer comprising a colorless or selectively absorbing metal oxide with a high refractive index, B) a second, non-selectively absorbing, semitransparent layer consisting essentially of carbon, a metal or a metal oxide, and optionally C) a third layer comprising a colorless or selectively absorbing metal oxide in combination with scattering color pigments which are complementary in color to the reflection color of the interference pigments are useful for preparing valuable documents that are forgeryproof.

    Abstract: A diesel fuel contains 0.1 to 2% (vol.) of a nitrate of a hydroxycarboxylic ester. Those preferred have the formula R1 being hydrogen, an aliphatic or an aromatic radical; R2 being hydrogen, an aliphatic or an aromatic radical; and R3 an aliphatic or an aromatic radical. Specified nitrates are those of methyl ethyl and isopropyl lactate, and that of methyl glycolate, acid urethyl hydroxy isobutyrate.
