摘要:
A dyestuff of the formula: ##STR1## in which A is thiazolyl, isothiazolyl, benzothiazolyl, benzisothiazolyl, thiadiazolyl, thienyl, or imidazolyl which is unsubstituted or substituted by one to three substituents selected from chlorine, bromine, methyl, phenyl, nitro, cyano, thiocyano, acetyl, carbalkoxy containing 2 to 5 carbon atoms and alkylsulfonyl containing 1 to 4 carbon atoms;X is hydrogen, chlorine, methyl, ethyl, methoxy, ethoxy, formylamino, acetylamino, propanoylamino, benzoylamino or cinnamoylamino;Y is hydrogen, methyl, ethyl, methoxy or ethoxy;R is hydrogen, alkyl containing 1 to 4 carbon atoms or the group of formula: ##STR2## said alkyl being unsubstituted or substituted by one hydroxy, alkoxy containing 1 to 4 carbon atoms, phenoxy, acetyloxy, cyano, alkylsulfonyl containing 1 to 4 carbon atoms, carbalkoxy containing 2 to 5 carbon atoms or alkoxycarbonyloxy containing 2 to 5 carbon atoms;N is equal to 1, 2 or 3; andZ is 2-cyanovinyl, 2-cyanoethyl or 2-chloro-2-cyanoethyl and which are useful as dispersion dyestuffs for dyeing and printing fibers of fibrous materials which are based on organic substances with high molecular weight, are hydrophobic and are wholly or partially synthetic.
摘要:
Disperse dyes of the formula ##STR1## in which D is the radical of a diazo component, Y is a linear or branched, unsubstituted or substituted alkylene of one to four carbon atoms;R.sup.1 is hydrogen, optionally substituted linear or branched alkyl of one to four carbon atoms, optionally substituted cycloalkyl or aralkyl, phenyl, or a radical of the formula: ##STR2## and R.sup.2 is hydrogen or C.sub.1 to C.sub.6 alkyl which may bear chloro, bromo or cyano as a substituent; andD and the rings A and B may bear one or more further substituents other than --SO.sub.3 H and --COOH;and also to their productions and their use for dyeing water-repellent fibrous materials. The dyes are eminently suitable for dyeing hydrophobic fibers, particularly polyesters, in yellow to blue-green shades of excellent fastness properties.

Dyestuff of the formula: ##SPC1##In which m is equal to 0 or 1, n is equal to 1, 2 or 3, A represents the residue of an aromatic or heterocyclic diazotizable amine devoid of solubilizing acid groups, the benzene ring B is unsubstituted or substituted by one or two atoms of chlorine or bromine or methyl, ethyl, methoxy, ethoxy or acylamino groups, X represents a hydrogen or chlorine atom or a methyl, ethyl, methoxy, ethoxy or acylamino group, Y represents a hydrogen atom or a methyl, ethyl, methoxy or ethoxy group, R represents a hydrogen atom, a mono substituted or unsubstituted alkyl group or a group of the formula: ##SPC2##And Z represents a 2-cyanovinyl, 2-cyanoethyl or 2-chloro-2-cyanoethyl residue; process for the preparation of dyestuffs of the above formula; process for coloring hydrophobic materials with such dyestuffs; hydrophobic materials colored with such dyestuffs and esters of the formula: ##SPC3##Wherein m, n, A, B, R, X, Y and Z have the meanings given above.
摘要:
Anthraquinone dyes of the general formula: ##STR1## wherein R.sup.1, R.sup.3, R.sup.4 and R.sup.6 are selected from the group consisting of H, OH, OCH.sub.3, NO.sub.2, NH.sub.2 and NHCH.sub.3 ; R.sup.2 and R.sup.5 are selected from the group consisting of:(a) alkyl-, aryl-, alkaryl-, alkoxyaryl-, aminoaryl-, alkylaminoaryl-, dialkylamino-, arylaminoaryl- or ##STR2## wherein R.sup.7 is selected from the group consisting of alkyl-, aryl-, amino-, alkylamino-, dialkylamino-, arylamino-, alkyloxy-, and aryloxy radicals,along with their syntheses routes are disclosed. The dyes are particularly useful in liquid crystal displays which function with a "guest host" effect or in other electrooptical display devices having a medium therein switchable between different ordering states.

摘要:
A process for the continuous dyeing of textile materials containing or consisting of synthetic fibrous materials from organic solvents, which comprises impregnating the said textile materials with an organic dyebath containing at least one dyestuff of the formula ##SPC1##In which the phenyl radical A is unsubstituted or substituted by 1 to 3 substituents of the group consisting of halogen, nitro, cyano, trifluoromethyl, lower alkyl, lower alkoxy and lower alkoxy-lower alkylene--O--, B represents naphthylene or ##SPC2##R.sub.2, r.sub.3, r.sub.4 and R.sub.5 each represent hydrogen, halogen, lower alkyl, lower alkoxy or lower alkoxy-lower alkylene--O--, and R.sub.1 stands for a linear or branched alkylcarbonyl of at most 18 carbon atoms, ##SPC3## ##SPC4## ##SPC5## ##SPC6##And an organic solvent, and fixing the dyestuffs by submitting the impregnated materials to a heat treatment.
