Abstract: There are described novel crystalline bromine and iodine salts of triazole dyes of the formula ##STR1## wherein R is the CH.sub.3 or C.sub.2 H.sub.5 group,R.sub.1 is a C.sub.1 -C.sub.4 -alkyl group,R.sub.2 is an unsubstituted or substituted C.sub.1 -C.sub.4 -alkyl group, andX is the bromine or iodine ion,and also processes for producing them, and their use for dyeing and printing in particular polyacrylonitrile materials.

Abstract: Novel blue naphtholactam compounds of the formula ##STR1## and their carbinol bases are described, in which formula R is hydrogen or a substituted or unsubstituted alkyl radical (C.sub.1 -C.sub.4), X is a --O-- or --S-- atom, R.sub.1, R.sub.2, R.sub.3 and R.sub.4 independently of one another are hydrogen or a substituted or unsubstituted alkyl group having 1 to 6 carbon atoms, or one or two of these substituents R.sub.1 to R.sub.4 is or are a substituted or unsubstituted aryl group; R.sub.5 is a substituted or unsubstituted C.sub.1 -C.sub.4 -alkyl group or a C.sub.2 -C.sub.4 alkenyl group; and R.sub.6 and R.sub.7 independently of one another are hydrogen, halogen or an alkyl or alkoxy group, each having 1 to 4 carbon atoms, and the rings A and/or B can also be mono- or poly-substituted, A is an anion and n is 0 or 1.

Abstract: There are described novel greenish-yellow cationic dyes of the formula ##STR1## wherein R.sub.1 is hydrogen, halogen, lower alkyl, lower alkoxy or NO.sub.2,R.sub.2 is unsubstituted lower alkyl, or lower alkyl which is substituted by: hydroxyl, lower alkoxy, halogen, CN, carboxylic acid amide, carboxylic acid alkyl ester or phenyl, or R.sub.2 is alkenyl (C.sub.3 -C.sub.4), theR.sub.3 's independently of one another are each lower alkyl, or both R.sub.3 's together form a carbocyclic 5-, 6- or 7-membered ring,R.sub.4 is hydrogen, lower alkyl, unsubstituted aryl or substituted aryl,R.sub.5, R.sub.6 and R.sub.7 independently of one another are hydrogen, lower alkyl, lower alkoxy, halogen, NO.sub.2, CN or lower alkylsulfonyl, andA is an anion;processes for producing them, and their use for dyeing and printing textile materials, particularly polyacrylonitrile materials.

Abstract: An azo dyestuff which is free from groups conferring solubility in water and has the general formula I ##STR1## in which R denotes hydrogen, halogen, a hydrocarbon radical with up to 18 carbon atoms which is bonded by means of a direct bond or a sulphur or oxygen atom and can be substituted, trifluoromethyl, cyano, dichlorocyanomethyl, chlorodicyanomethyl, tribromomethyl or trichloromethyl or denotes a heterocyclic radical containing nitrogen, Hal is a halogen atom, R.sub.1 is an optionally substituted alkyl group and "acyl" denotes the acyl radical of an organic carboxylic acid, carbamic acid, carbonic acid or sulphonic acid with, preferably up to 0.18 carbon atoms. The new dyestuffs dye polyester fibers in fast red shades.

Abstract: There are described new cationic dyes of the formula ##STR1## wherein R 's independently of one another each represent a straight-chain or branched-chain alkyl group having 1 to 4 carbon atoms,X represents CH or N,R.sub.1 represents hydrogen in the case where X=CH, or represents a straight-chain or branched-chain alkyl group having 1 to 6 carbon atoms in the case where X=N,Z represents unsubstituted or substituted alkylene which has 2 to 4 carbon atoms and which can be interrupted by one or more hetero atoms,n represents 0 or 1, andT represents an anion, and the ringsA and/or B can optionally contain further substituents,processes for producing these dyes, and their use for dyeing and printing materials dyeable with cationic dyes, for dope dyeing textile materials consisting of homo- or copolymers of acrylonitrile, and for dyeing wet tow, by which means are obtained yellow dyeings having good fastness properties.

Abstract: New yellow cationic dyes of the formula ##STR1## ARE DISCLOSED WHEREIN X represents hydrogen or halogen,R represents an optionally substituted alkyl group or cycloalkyl group,Or --CH.sub.2 -- if this is linked with the phenylene group in the o-position with respect to the oxygen bond to form a 6-membered ring and n represents 1,R.sub.1 represents an unsubstituted, straight-chain or branched-chain alkyl group having 1 to 5 carbon atoms,R.sub.2 represents a substituted, or preferably unsubstituted, straight-chain or branched-chain alkyl group having 1 to 5 carbon atoms,N represents the numbers 1 or 2, andAn represents an anion, which dyes are useful for dyeing and printing of textile material especially polyacrylonitrile.
