Abstract

514,770. Dyes. COFFEY, S., LODGE, F., and IMPERIAL CHEMICAL INDUSTRIES, Ltd. May 4, 1938, No. 16318/37. [Class 2 (iii)] Dyes are made by brominating 1.4-di-pbutylanilinoanthraquinone, in which one or both anilino groups may carry a methyl substituent and then sulphonating. The products dye wool blue or violet shades. In examples, 1.4-bis- (p-n-butylanilino) anthraquinone and 1.4-bis-(2<1>-methyl-4<1>-n-butylanilino) anthraquinone are brominated in chloroform, followed by suplhonation of the products. Specifications 446,819, 449,010 and 494,802 are referred to.
