摘要:
The use of a polybasic acid and a volatile base, or a salt formed by the said acid and base, in an aqueous ink to increase the water-fastness of a water-soluble dye contained in the ink. Also claimed are novel aqueous inks containing an organic polybasic acid and a volatile base, a method of ink jet printing using the inks, a substrate printed with the inks and an ink jet printer cartridge containing the inks.
摘要:
An ink comprising water, a water-dissipatable polymer and one or more dyes having a benzene ring carrying a hydroxy group at each of the 1-, 3- and 5-positions and an azo group at each of the 2-, 4- and 6-positions or a tautomer thereof.Also claimed are certain dyes, compositions printer cartridges and ink jet printers.
摘要:
A compound of the formula (1) ##STR1## or a salt thereof wherein J is a group of the formula (1a) ##STR2## and A, Y, T, T.sup.1, R, R.sup.1, R.sup.4, R.sup.5 and R.sup.6 are as defined in the specification are useful as black colorants for ink jet printing inks.
摘要:
Dye mixtures comprising at least one dye of the formula (1) ##STR1## together with at least one dye of the formula (2) or (3) ##STR2## in which the substituents are as defined in claim 1 are direct dyes for cellulosic fibre materials in particular. They are stable at high temperatures and are particularly suitable for the one-bath, single-stage dyeing of polyester/cotton blends with a disperse dye for the polyester fibres under the dyeing conditions for polyester fibres.
摘要:
Disazo dyes formula (VIII) ##STR1## or of formula (IX) ##STR2## Where A, R.sub.1, R.sub.2, n and M are as defined in the specification are excellent dyes for ink jet printing.
摘要:
A compound of Formula (1) or a salt thereof: wherein:J is --OR.sup.4 or --NR.sup.4 R.sup.5 ;R.sup.4 is H or optionally substituted alkyl, aryl or acyl; andR.sup.4 and R.sup.5 taken together with the N atom to which they are attached form a 5- or 6-membered carbocyclic group optionally containing a ring oxygen atom;A is optionally substituted phenylene or optionally substituted naphthylene;Y is a substituted or unsubstituted naphthylene or phenylene ring;R.sup.1 is H or optionally substituted alkyl, alkylcarbonyl, alkylsulphonyl, alkoxycarbonyl, alkoxysulphonyl, arylcarbonyl or arylsulphonyl;T and T.sup.1 each independently is H or SO.sub.3 H; andR is, for example, H or optionally substituted alkyl or aryl. The compounds are used as black colorants for ink jet printing inks.
摘要:
A process for the preparation of diazo pigment mixtures, which comprises condensing 2 mol of an azocarboxylic acid chloride of formula ##STR1## with 1 mol of a mixture of diamines of formulae ##STR2## at a molar ratio of II:III:IV from 0-30:5-60:40-95,the condensation and isolation of the product obtained being carried out by customary methods.The diazo pigment mixtures so obtained are distinguished by high color strength and chroma.
摘要:
The invention provides a process for the production of azodyes and their derivatives by diazotization and coupling reactions and optionally further modification reactions, wherein a compound of formula ##STR1## in which E signifies an aromatic bivalent radical,X.sub.1 signifies hydroxy or a primary amino group,Y.sub.1 signifies hydroxy or a primary amino group and in which the aminogroup linked to the --SO.sub.2 --bound phenyl radical may optionally be acylated,or a mixture of compounds of formula (I), is employed as a coupling component or/and--in the non-acylated form--as a diazo component, the invention in particular relates also to the novel dyes and their use and to the novel intermediates.
摘要:
Process for the production of a flocculation-resistant pigment, comprising after-treating an arylamide pigment which has been subjected to a dyestuff treatment, the after-treatment comprising a further treatment of the dyestuff-treated arylamide pigment with an arylamide yellow dyestuff, under alkaline conditions at elevated temperature.
