Abstract: Flaky mica pigments coated with metal oxides are prepared by oxidizing vaporizable metal carbonyls to metal oxides with oxygen at an elevated temperature in the presence of mica flakes which are kept in motion. The amount of carbonyls introduced into the reaction zone does not exceed 5% by volume of the amount of other gases introduced. The coated mica pigments are employed as pigments in surface coatings, plastics and glasses.

Abstract: The pigment preparations contain a) a finely divided pigment, b) at least one colourant containing at least one external basic group, c) at least one acidic and/or neutral phosphoric acid ester and d) optionally further assistants which are conventional in preparations of this type. The preparations are used for pigmenting printing inks and surface coatings (paints). The printing inks, pastes and surface coatings prepared using the preparations have significantly better flow properties than the inks and coatings obtained using pigments of the prior art.

Abstract: To prepare a colored pigment which has a metallic luster and consists of a metallic core whose surface is at least partially covered with an iron oxide, iron pentacarbonyl is oxidized with oxygen in a fluidized bed of the metallic cores at above 100 DEG C. The amount of iron pentacarbonyl vapor introduced into the fluidized bed must not exceed 5% by volume, based on the total gases introduced into the fluidized bed over the same period of time.

Abstract: Prodn. of a readily dispersing fine-grain, brown pigment having the formula: CrxFe2-xO3 (in which 0.1=x=1) is improved in that an aq. soln. of CrO3 (pref. concn. 45-63 wt.%) and/or gaseous CrO2Cl2 is introduced in the form of a spray into a reaction zone in presence of water vapour, gaseous Fe(CO)5 and O2; the reaction is carried out at a temp. >700 degrees C (pref. 700-1000 degrees C); and the resulting solid reaction product remains in the reaction zone for at least 1 sec. (pref. up to 10 sec.) before the withdrawal. These pigments are temp. resistant and light fast. Their prodn. is more convenient than the usual wet coprecipitation of the components, with subsequent sepn. and calcination. These are no- by-products, and high purity pigments are obtd. The colour can be easily controlled (increasing Cr content and, to a lesser extent, prolonged residence time give darker brown colouration.).

Abstract: Dyes are of formula (I): (where X is the residue of a methylene-active cpd. an aromatic or heterocyclic primary amine, R1 is H or 1-4C alkyl, R2 is 1-4C alkyl, phenyl opt. substd. by Cl, Br, OH, CH3 and/or CH3O, indoyl-2, 2-phenyl indolyl-3- or 2,4-dihydroxyquinolyl-3-gp. or R1 and R2 together with the methylene C atom form a 6-membered carbocycle or a 5- or 6-membered heterocycle opt. joined to a benzene nucleus). Prepared e.g. by condensing a cpd. (I) where the -N=CR1R2 gp. is replaced by H, with a hydrazone H2N-N=CR1R2. e.g. a yellow dye is obtained by condensing 1-(cyano-carbonamido)-3-imino-isoindolene with 3-acetyl-2:4-dihydroxy-quinoline hydrazone.
