Abstract:
Provided is a curable ink composition, in particular a curable inkjet ink composition. The ink composition has a dye monomer, a carrier monomer and an initiator. The dye monomer has a chromophore moiety that is covalently bonded to at least one polymerizable functional group and is present at 1.0 wt % or more based on total weight of the ink composition. The carrier monomer has at least one polymerizable functional group and is present in at 50 wt % or more based on total weight of the ink composition. The ink compositions are suitable for radiation curing such as UV curing and have good cure properties or light fastness properties.
Abstract:
According to the invention, a process for the preparation of triphendioxazines systemetrically or asymmetrically amidated on both sides comprises reducing a triphendioxazine chromophore, which is optionally already amidated on one side, to give the leuco form end amidating and re-oxidizing the leuco form. Products amidated on both sides are obtained in this manner with a high yield and product quality. Novel triphendioxazine dyestuffs are furthermore prepared in this manner.
Abstract:
A method for detecting a component of an aqueous liquid comprising adding to the liquid a luminescent dye selected from the group consisting of cyanine, merocyanine and styryl dyes containing at least one sulfonic acid or sulfonate group attached to an aromatic nucleus and reacting the dye with the component. The labeled component is then detected by an optical detection method.

Abstract:
On testing triphendioxazine reactive dyes it was found that they are unsuitable for almost all conventional single-step printing processes since they are not stable under these conditions.In the course of the development of an uncomplicated single-step printing process for these dyes, it has been found according to the invention, then, that by replacing the customary fixing alkali (NaHCO.sub.3) by stoichiometrically specific amounts of sodium acetate or sodium trichloroacetate or certain mixtures of sodium trichloroacetate and sodium acetate it is possible to fix triphendioxazine reactive dyes in full yields without change in hue. In addition, it is possible to print conventional print pastes.
Abstract:
Dyestuffs of the formula ##STR1## in which R.sub.1, R.sub.2 =H, Cl, Br, optionally substituted C.sub.1 -C.sub.4 -alkyl or C.sub.1 -C.sub.4 -alkoxy, carbonyl, aryloxy optionally substituted carboxamide or acylamino,R.sub.3 =H, optionally substituted C.sub.1 -C.sub.4 -alkyl or C.sub.1 -C.sub.4 -alkoxy, Cl or Br,R.sub.4 =H or alkyl,B=an aliphatic or arylene bridge member,Z=H or fiber-reactive radical,n=0 or 1.These dyestuffs are highly suitable for dyeing and printing hydroxyl- and amides-containing materials and produce red dyeings and prints having good wet- and light-fastness properties.
Abstract:
The invention relates to chromium complexes of the formula ##STR1## in which A is the radical of a dicyclically metallizable azo or azomethine dye, B is the radical of a potentially at least bidentate bianionic complexible organic compound which contains no azo or azomethine group, L is a colorless monofunctional ligand, X is a fibre-reactive radical, Ka is a cation, K is 0 or 1, m is 1, 2 or 3, n is 1 or 2, and the X radical and the SO.sub.3.sup..crclbar. Ka group are each bonded to the radicals A and B, to a process for preparing the chromium complexes of the formula (1), and to a combined preparation and dyeing process.
Abstract:
The present invention provides new triphendioxazine dyestuffs of the formula ##STR1## wherein W represents an optionally substituted sulphonamide groupZ represents a reactive group or hydrogen and the other substituents are defined as in the text of the application.The new reactive dyes are highly suitable for dyeing and/or printing hydroxyl-containing and/or amide-containing fibre materials. The dyestuffs where Z is H are intermediates in the preparation of the reactive dyestuffs.
Abstract:
Dyestuffs of the formula ##STR1## WHEREIN (R).sub.n represents n substituents R each of which may be independently halogen, lower alkyl, lower alkoxy or COOHR.sup.1 is H, optionally substituted lower alkyl, optionally substituted aryl or optionally substituted aralkyl,n is 0-3,(a+b) is 0-4,X is O, S or NR.sup.2, where R.sup.2 is H or optionally substituted lower alkyl,Y is an optionally substituted aliphatic or optionally substituted araliphatic linking group, andEach Z is independently a H or a cellulose-reactive group, and when (a+b) is O there is at least one SO.sub.3 H group as substituent on the groups R.sup.1, X or Y.The dyestuffs when both Z are H are valuable acid dyes, e.g. for wool, and when one or both Z are reactive groups the dyestuffs are valuable reactive dyestuff especially for cellulose fibers.
