Aqueous preparations containing insoluble or difficultly soluble dyes

Aqueous preparations containing insoluble or difficultly soluble dyes. Lauton, Alain; Koci, Zdenek (Ciba-Geigy A.-G. , Switz.). Eur. Pat. Appl. EP 108721 A1 16 May 1984, 17 pp. DESIGNATED STATES: R: CH, DE, FR, GB, IT, LI. (German). (European Patent Organization). CODEN: EPXXDW. CLASS: IC: C09B067-40; C09B067-30; D06P001-52; D06P001-667. APPLICATION: EP 83-810500 31 Oct 1983. PRIORITY: CH 82-6415 4 Nov 1982. DOCUMENT TYPE: Patent CA Section: 40 (Textiles) Section cross-reference(s): 41 Aq. dye compns contg. an anionic dispersing agent and a telomer prepd. from hypophosphorous acid and a,b-unsatd. carboxylic acid(s) exhibit good storage stability and redispersibility and give dyeings with low tendency for dye migration during the drying stage after impregnation and squeezing of the textile. Thus, a suspension of 5-(4-chloro-2-nitrophenylazo)-3-cyano-1-ethyl-6-hydroxy-4-methyl-2-p yridone [70528-90-4] 27.3, anionic dispersant 5, 43% aq. acrylic acid-Na hypophosphite telomer [73256-97-0] (mol. wt. ~1000) 25, 37% aq. HCHO 0.4, glycerol 20, and H2O 22.3 parts was milled to particle size 1 m to give a prepn. with storage stability 1 mo at +40°, +50°, and -10° and good redispersibility. When applied to polyester-cotton from a pad bath the prepn. exhibited excellent migration resistance during intermediate drying and gave a uniform dyeing.

DOCUMENT TYPE: Patent CA Section: 74 (Radiation Chemistry, Photochemistry, and Photographic and Other Reprographic Processes) Disclosed is the toner comprising a binder resin, a colorant, a release agent, and a charge controller formed from a di- or trivalent metal and a hydroxycarboxylic acid I (R1,2 = H, alkyl, alkenyl, alkoxy, etc.; and m, n = integer 0-5), wherein (a) the colorant is C.I. Disperse Yellow 42, 64, 201, and/or 211, (b) a THF sol.Several substances with their cas registry numbers 70528-90-4 and 89993-86-2 may be metioned in this study. component of the toner has a GPC wt. av. mol. wt. 1,000 - 600,000, and (c) the toner has an av. sphericity 0.920-0.995 with the std. deviation <0.040. The toner exhibited excellent translucent property for yellow image OHP projection. .
