Abstract:
The invention provides a water-soluble ink capable of forming an image having good color hue and high fastness in various use and environmental conditions, which comprises a coloring composition comprising a disazo dye represented by the following formula 1: A1-NnullN-A2-NnullN-A3 and at least one other dye having a specific structure; in formula 1, A1, A2 and A3 each independently represents an aromatic group which may be substituted or a heterocyclic group which may be substituted, and A1 and A3 each is a monovalent group and A2 is a divalent group.
Abstract:
The present invention relates to reactive dyes of the general formula (1) 1 where Y is a heterocyclic reactive group of the general formula (2) or (3) 2 where X1 to X5 are each as defined in claim 1, their preparation and their use for dyeing and printing hydroxyl- and/or carboxamido-containing materials.
Abstract:
The invention relates to reactive dyes containing a halobenzene nucleus and, in particular, reactive dyes containing a halobenzene nucleus and two or more reactive components.
Abstract:
A compound of the Formula (1) and salts thereof: 1 wherein: D is the residue of a mono-azo chromophore; Z is an optionally substituted nitrogen containing heterocyclic group; R1 is H or optionally substituted alkyl; the dyes of Formula (1) being free from fiber reactive groups; provided that the compound of Formula (1) is other than the compound of Formula (A): 2 Also claimed are compositions and inks containing a compound of Formula (1), a process for ink jet printing using the inks and to an ink jet printer cartridge containing the ink.
Abstract:
The present writing relates to a novel fiber-reactive dye of the formula 1 wherein R11, D, R0, X and Z are as defined in the specification. The novel dye according to the present writing can be used in dyeing and printing fibre materials, especially, cellulosic fibre materials by a general fixing method, and a good adsorbing/fixing rate and an excellent fastness to light and wet treatment.
Abstract:
Compounds of the formula 1 in which the variables are as defined in the claims, which are suitable as fiber-reactive dyes for dyeing widely varying fiber materials, are described.
Abstract:
A method of printing cellulosic fiber materials in which the fiber material is brought into contact with reactive dyes of formula 1 wherein A is the radical of a monoazo, polyazo, metal complex azo, anthraquinone, phthalocyanine, formazan or dioxazine chromophore, R1, R2 and R3 are each independently of the others hydrogen or unsubstituted or substituted C1-C4alkyl, X1 and X2 are halogen, B is an organic bridging member, T is a reactive radical of formula 2 R4 is hydrogen, C1-C4alkyl unsubstituted or substituted by hydroxy, sulfo, sulfato, carboxy or by cyano, or a radical 3 null, wherein R5 is as defined hereinbelow, R5 is hydrogen, hydroxy, sulfo, sulfato, carboxy, cyano, halogen, C1-C4alkoxycarbonyl, C1-C4alkanoyloxy, carbamoyl or a group nullSO2nullY, R6 is hydrogen or C1-C4alkyl, alk and alk1 are each independently of the other linear or branched C1-C6alkylene, arylene is an unsubstituted or sulfo-, carboxy-, hydroxy-, C1-C4alkyl-, C1-C4alkoxy- or halo-substituted phenylene or naphthylene radical, Y is vinyl or a radical nullCH2nullCH2-U and U is a leaving group, Y1 is a group nullCH(Hal)-CH2(Hal) or nullC(Hal)nullCH2, wherein Hal is chlorine or bromine, W is a group nullSO2nullNR6null, nullCONR6null or nullNR6COnull, wherein R6 is as defined hereinabove, Q is a radical nullOnull or nullNR6null, wherein R6 is as defined hereinabove, n is the number 0 or 1, and V1 and V2 are each independently of the other N, CnullH, CnullCl or CnullF, and the fixing of the printed fiber material is carried out without an additional fixing process step. The prints obtained are distinguished by brilliant colour shades and good allround properties.
