    Abstract: Triaminotriarylmethane colorants are obtainable by first reacting an aluminum or iron trihalide complex of a 4,4',4''-trihalotriphenylmethyl halide with a metanilic acid, a sulfanilic acid or a beta -naphthylaminesulfonic acid and then reacting the product with one or more anilines to replace the halogen atoms located in the 4-positions. The compounds according to the invention are very useful as pigments, for example in printing inks, or for toning carbon black.

    Abstract: The invention relates to basic chromium aluminum sulfates which are soluble in cold water and are of the general formula CrxAl2-x(OH)2y. (SO4)3-y.n H2O where x is from 0.1 to 1.9, y is from 0.01 to 2 and n is from 4 to 24, and a process for the preparation thereof. The process comprises reacting chromium (III)-containing waste sulfuric acid having a water content of 20-50% by weight with aluminum oxide and/or aluminum oxide hydroxide and/or aluminum hydroxide at a temperature of 100 DEG to 200 DEG C. The molten product is converted to droplet form and allowed to solidify in free fall.

    Abstract: 1,273,047. Water-insoluble monoazo dyes. BADISCHE ANILIN- & SODA-FABRIK A.G. 19 Sept., 1969 [21 Sept., 1968], No. 46199/69. Heading C4P. The invention comprises water-insoluble azo dyes having the general formula I in which R and R 1 are alkyl radicals having one to four carbon atoms, X is hydrogen, a methoxy group or an ethoxy group, Y is hydrogen, chlorine, bromine or a methyl, ethyl, methoxy, ethoxy, acetylamino or propionylamino group and n is 1 or 2. The red to blue dyestuffs of the invention may be prepared conventionally by diazotization and coupling.
