摘要:
The present invention relates to azo dyes of formula wherein R1 denotes hydrogen or C1-C12alkyl which is unsubstituted or substituted by one or more C1-C12alkoxy groups, C1-C12alkylcarbonyl groups, C7-C25arylcarbonyl groups, hydroxyl groups, amino groups, cyano groups or halogen atoms and which may be interrupted one or more times by the radical —O—, —S—, —NR4—, —COO— or —OOC—, R4 is hydrogen or C1-C12alkyl; X is hydrogen or halogen; and R2 and R3 are each independently of the other hydrogen; C1-C12alkyl which is unsubstituted or substituted by cyano, carboxy, hydroxy, C1-C6alkoxy or C2-C8alkoxyalkoxy; or are C7-C25aralkyl which is unsubstituted or substituted by cyano, carboxy, hydroxy, C1-C6alkoxy or C2-C8alkoxyalkoxy, to mixtures containing said dyes and to the use thereof in dyeing or printing semi-synthetic and especially synthetic hydrophobic fibre materials, more especially textile materials.
摘要:
A disperse dye composition, disperse dye and preparation method and use thereof are described. The disperse dye is suitable for fabrics, particularly for dyeing and printing of dacron and blended fabrics thereof.
摘要:
A composition including a disperse dye and an aqueous carrier having a first polyol and a second polyol having at least 5 carbon has atoms, wherein the composition has a color fastness to water of at least 3 according to International Organization for Standardization test ISO 105-EO1:2010 when used in direct inkjet printing on a ready-to-print polyester textile.
摘要:
A method for manufacturing printed textiles includes the steps of: a) inkjet printing an image onto a textile substrate with one or more inkjet inks including an aqueous medium and capsules composed of a polymeric shell surrounding a core which contains one or more thermally curable compounds; and b) thermally fixing the inkjet printed image. Inkjet printed textiles contain a printed image on a textile substrate wherein pigments and/or disperse dyes are at least partially encapsulated by polymeric shell material from capsules composed of a polymeric shell surrounding a core.
摘要:
Methods for dyeing of microporous track etched membranes are provided. In particular, these methods are suitable for dark shade dyeing of membranes having large pores with low porosity. Desirably, such methods provide dyed membranes wherein the membrane parameters are not significantly changed as compared to those prior to dyeing. Likewise, the resultant dyed membranes exhibit no negative influence on sensitive cell culture system applications.
摘要:
The present invention provides dye mixtures containing at least one dye of formula (I) and at least one dye of formula (II) where T1, T2, R1 to R9 and n are each as defined in claim 1, processes for their preparation and their use.
摘要:
The present invention relates to an azo dye of formula (1), wherein R1 is the radical of a diazo component of the benzene, naphthalene, diphenyl, azobenzene, thiophene, benzothiazole, thiadiazole, indazole, benzatriazole, pyrazole, anthraquinone, naphtholic acid imide, chromone, phthalimide or diphenylene oxide series, R2 is an unsubstitued or substitued aryl radical or an unsubstituted or substituted aralkyl radical and R3 is an unsubstituted or substituted aryl radical or an unsubstituted or substituted aralkyl radical, with the proviso that one of the substituents R2 and R3 is an unsubstituted or substituted aryl radical and the other is an unsubstituted or substituted aralkyl radical, 2-hydroxy-2-phenylethyl being expected as a substituted aralkyl radical, to mixtures comprising at least two structually different azo dyes of formula (1) and to the use of those azo dyes and dye mixtures in the dyeing or printing of semi-synthetic or synthetic hydrophobic fibre materials.
摘要:
The present inventions refers to a dye mixture comprising from 25 to 80% by weight with respect to the total dyestuff fraction of the yellow dyestuff represented by the structural formula [1] and from 75 to 20% by weight with respect to the total dyestuff fraction of a yellow dyestuff represented by the structural formula [2] wherein R denotes a C1 to C4 hydroxyalkyl group.
