Solid anionic dye compositions with good cold water solubility

Solid anionic dye compositions with good cold water solubility. Balliello, Paolo (Ciba-Geigy A.-G. , Switz.). Ger. Offen. DE 3212408 A1 13 Oct 1983, 12 pp. (German). (Germany). CODEN: GWXXBX. CLASS: IC: C09B067-24. APPLICATION: DE 82-3212408 2 Apr 1982. DOCUMENT TYPE: Patent CA Section: 40 (Textiles) Section cross-reference(s): 41 The cold water soly. of solid anionic dye compns. contg. 31 anionic dye, 31 anionic dispersant, a nonionic emulsifier, and other optional additives is improved by the presence of 0.1-10 wt.% of a quaternary ammonium compd. of formula RR1R2R3N+ X-, where X- = anion, R = C8-20 alkyl or alkenyl, and R1, R1, and R3 = C1-4 alkyl. The prepns. are used in dyeing or printing of polyamide or wool textiles. For example, a prepn. comprising I [25797-81-3] 86, ligninsulfonate 0.86, nonionic emulsifier 3.4, C10H7SO3H-HCHO condensate 3.4, cetyltrimethylammonium chloride (II) [112-02-7] 0.In this experiment, several chemicals are used like 9017-33-8 and 9004-98-2 45, foam suppressing surfactant 0.85, and moisture 5% had cold water soly. 30 g/L as compared to <1 g/L when II was omitted from the formulation. .
