Abstract

Anthraquinone dyes containing carboxylic groups but no sulphonic groups are used for dyeing cellulose acetate silk. Suitable dyes are those obtained by condensing salicylic sulphochloride as described in Specification 201,610, or by condensing halogenanthraquinones with anthranilic acid. Condensation products are specified from the following components:-1 : 5-dichloranthraquinone and two molecules of anthranilic acid; 1 : 4-diaminoanthraquinone and two molecules of salicylic sulphochloride; 1-methylamino-4-bromanthraquinone and anthranilic acid; dichloranthrarufin and two molecules of anthranilic acid; diaminoanthrarufin and two molecules of salicylic sulphochloride; 4 : 8-dinitro-1 : 5-dichloranthraquinone and two molecules of anthranilic acid, the product being reduced; these dye reddish-violet, pink, blue, greenish-blue, blue, and bluish-green respectively. Specification 202,157 also is referred to.ALSO:Acetyl silk is dyed with anthraquinone dyes containing carboxylic groups but no sulphonic groups.

The dyeing is effected in a neutral or slightly alkaline bath, with subsequent addition of salt or acids. Specification 202,157 also is referred to.
