摘要:
Stabile konzentrierte wäßrige Lösungen von insbesondere anionischen Azo-Reaktivfarbstoffen erhält man auf verhältnismäßig einfache Weise, indem man anstelle der sonst üblichen Mineralsäuren aromatische Sulfonsäuren sowie gegebenenfalls säuregruppenhaltige Ionenaustauscher als Säurespender für die Diazotierung verwendet.
a) 30-70 Gew.% eines Farbstoffes der Formel (I) worin R, und R 2 unabhängig voneinander je einem Alkylrest mit 1-4 C-Atomen bedeuten. b) 10-40 Gew.%Polyäthlenglykol c) 10-40 Gew.% eines anionischen Dispergiermittels, sowie gegebenenfalls d) einenwasserlöslichen Celluloseätherund/oder e) weiterezusätze.
Diese Präparate dienen zur Herstellung nicht gelierender Färbebäder, Klotzflotten oder Druckpasten für das Färben oder Bedrucken von Polyamidmaterial.
摘要:
An ink jet ink composition for textile printing including a dye and 5% to 30% by mass of a cyclic amide that is liquid at normal temperature and that has a normal boiling point in the range of 190°C to 260°C, wherein the hue angle ∠h° defined by the CIELAB color space on a recording medium ranges from 15 to 80 degrees.
摘要:
A method of coloring a cellulosic material which includes: a) dispersing pulped cellulosic material into water; and b) coloring the pulped cellulosic material by adding a cationic dispersion to the water, where the dispersion includes: (i) at least one pigment; (ii) water; and (iii) at least one quaternary salt of a styrene maleimide imide resin in an amount effective to disperse the pigment. The cationic dispersion may be prepared by (i) mixing, at 500 to 10,000 rpm, at least one pigment; water; and either (a) at least one a quaternary salt of a styrene maleimide imide resin or (b) at least one styrene maleimide imide resin in combination with at least one weak acid, thereby forming a dispersion premix; (ii) milling the dispersion premix in a mixer filled with ceramic, metal or glass beads for a period of time sufficient to reduce pigment agglomerates to primary particles, thereby forming a nonstandardized dispersion; and (iii) standardizing the dispersion against a color standard by adding water. The resulting cationic dispersion can be used to color cellulosic materials such as cotton and paper.
