Reactive dye, and composition, preparation method and application thereof

The invention discloses a reactive dye, and a composition, a preparation method and an application thereof. The preparation method for a compound as shown in a formula (1) described in the specification comprises the following steps: subjecting a compound as shown in a formula (2) described in the specification to a condensation reaction with compounds as shown in a formula (3) and/or a formula (4) in water under the condition that the pH value is 6.5 to 7.5 so as to prepare the compound as shown in the formula (1). The reactive dye provided by the invention has optimums like complete chromatography of a monochloro s-triazine reactive dye, excellent fastness indexes, no staining in white bottom and large solubility, has high fixation rate capable of reaching 80% or above, reduces the waste of a dye, is green and environment-friendly, reduces printing cost, and is more applicable to industrial production. The reactive dye provided by the invention is applicable to printing, dip dyeing and continuous dyeing on fibers like cotton and hemp and protein fibers like wool and silk, and has simple preparation method, cheap raw materials and significant economic benefits and environmental benefits.

A new kind of H-acid monoazo-anthraquinone reactive dyes with surprising colour

A new kind of reactive dyes containing both monoazo and anthraquinone chromophores was obtained by using 1,4-bis((4-aminophenyl)amino)anthrancene- 9,10-dione as diazo component and 1-amino-8-naphthol-3,6-disulfonicacid (H-acid) derivatives as coupling components. The dyes were characterized by UV-Vis, IR, MS, 1H NMR and 13C NMR. The results showed that the maximum absorption wavelengths of the dyes were all about 590 nm, which indicated that they were a kind of blue dyes. 1H NMR and 13C NMR results revealed that there were two kinds of tautomerisms in dye structure and a new conjugated system formed between the anthraquinone ring and the phenyl azo linkage. Density functional theory (DFT) calculations also proved the formation of the new larger conjugated system from which the blue colour was generated. The fixations of the dyes on cotton were over 88% and the light fastness reached 5 grade.

Colorimetric studies of heterocyclic monoazo reactive dyes and their dyeing applications on cotton, silk, and wool fibers

Heterocyclic quinazolinone-based hot brand monoazo reactive dyes were obtained by diazotization of 3-(4-aminophenyl)-2-phenylquinazolin-4(3H)-one and coupling with a variety of cyanurated coupling components. All the heterocyclic hot brand monoazo reactiv

PORPHYRAZINE DYE, INK, INK SET, AND COLORED MATTER

The present invention relates to a porphyrazine coloring matter represented by the following formula (1): (wherein, A, B, C and D independently represents a 6-membered ring having aromaticity, at least one or more is a benzene ring, at least one or more contains a nitrogen-containing heteroaromatic ring; in addition, E represents alkylene and each of X and Y independently represents a substituted or unsubstituted anilino group or a substituted or unsubstituted naphthylamino group; and b is 0 to 2.9, c is 0.1 to 3 and the sum of b and c is 1 to 3) which has a good hue as a cyan ink, is excellent in light fastness, ozone fastness and moisture fastness, and does not cause bronze phenomenon, as well as is thus suitable for inkjet recording.
