Also Ionamine.
[f. ion + amine.]
Any of various [(arylazo)arylamino] methane sulphonates, X·N2·Y·NRCH2SO3Na (where X and Y are (substituted) benzene nuclei), formerly used as specific dyes for acetate silk.
1922Glasgow Herald 24 Apr. 10 The ‘ionamines’ will have nothing to do with this homely fibre [sc. cotton]. They will only dye silk, either real or artificial. 1923Green & Saunders in Jrnl. Soc. Dyers & Colourists XXXIX. 12/1 Those Ionamines which are derived from primary amido compounds or contain free amido groups are capable of being diazotised upon the fibre, and in combination with various developers produce a wide range of shades from orange to scarlet, red, maroon, violet, blue and black. 1946S. R. & E. R. Trotman Bleaching, Dyeing & Chem. Technol. Textile Fibres (ed. 2) 474 The chief advantages of the ionamines are (i) ready solubility, and (ii) miscibility with direct dyestuffs. 1971R. L. M. Allen Colour Chem. i. 12 Systems in which the solubilising groups are eliminated by hydrolysis during or after dyeing have also been used in dyes such as the Ionamine (British Dyestuffs Corp.) and Neocotone..ranges, but these have now been superseded. |
