Abstract

324,966. Carpmael, A., (I. G. Farbenindustrie Akt.-Ges.). Oct. 10, 1928. Triarylmethane dyes, fast to alkalies and light are obtained from aromatic aldehydes containing a sulphonic acid group in the ortho position, and a primary aromatic amine containing no sulphonic group. In an example, benzaldehyde-2- : 4-disulphonic acid and m-xylidine are condensed, the oxidized leuco compound dyeing wool from an acid bath a bluish violet shade. The acid dyestuff from o-toluidine and benzaldehyde-o-sulphonic acid dyes silk violet shades. Benzaldehyde-2 : 5- and 2 : 6-disulphonic acids and 5-chlorbenzaldehyde-2 : 4-disulphonic acid are also mentioned as components. Specifications 1212/81, 21365/00 and 299,473 are referred to.
