Abstract: A process for the preparation of new dyestuff compositions which contain one or more basic dyestuffs in the form of dyestuff bases from the series of the triarylmethane, indoldiarylmethane, azine, oxazine, thiazine or xanthene dyestuffs or one or more basic dyestuffs of the series of the azo, anthraquinone, phthalocyanine, styryl, quinophthalone, benzoxanthene, naphthoylene-benzimidazole, naphthalimide or nitro series, carrying a primary, secondary or tertiary amino group or a guanidino or hydrazino group, as well as one or more non-ionic or slightly cationic surface-active agents and, optionally, water and/or an organic solvent miscible with water, which process comprises synthesizing the dyestuff in the surface-active agent optionally containing water and/or an organic solvent miscible with water, and then adding, if necessary, water and/or a solvent miscible with water and a further surface-active agent, this process of the invention having the advantage that an intermediate isolation, drying or grinding of the dyestuffs contained in the dyestuff compositions defined above is not necessary, so that the dyestuffs need not be introduced as substance into the surface-active agent and the solvent in a process wherein compositions of this type are prepared by a usual mixing, kneading or melting process; moreover, higher dyestuff yields are obtained in the dyestuff synthesis, and it allows to prepare dyestuff compositions from dyestuffs which are difficult to be isolated in substance after synthesis and often precipitate as oily or smeary products. The dyestuff compositions obtained according to the process of the invention, which are pastes or liquids, have a high stability upon storage. After being diluted with an aqueous solution of an amount at least equivalent to the dyestuff of an inorganic or organic acid, as well as, optionally, after the addition of dyeing and/or printing auxiliaries, the novel dyestuff compositions are suitable for dyeing or printing textile material containing acid groups.

Abstract: Improvement of a process for spin-dyeing acid-modified polymers or copolymers of acrylonitrile in which cationic quaternary dyestuffs are added to the spinning mass and spun according to the wet-spinning procedure. The improvement is characterized by using dyestuffs characterized by a migration factor M of 20 or less than 20, by a combination index K of less than 2.5 and a cation weight of more than 310. Migration factor M and combination index K are known values in the dyestuff field or can be determined. The dyestuff to be used according to the invention can belong to the most different classes of dyestuffs; they fix rapidly on the polymer, and thus they do not color, or color only to a minor extent, the coagulation, stretching and washing baths although they are soluble in water and aqueous solutions of these baths. The fibers and filaments obtained by the process of the invention have outstanding fastnesses to wet processing and, owing to the absence of dyestuff aggregates at the surface of the fiber such as occur when spin-dyeing with pigments, very good fastnesses to dry and wet rubbing. The fibers are intense, absolutely transparent and free from specks.

Abstract: A dyeing process has been found which enables to dye uniformly polyacrylonitrile fiber materials, by using as dyestuffs basic azo dyestuffs being non-quarternized and containing neither cationic quaternary ammonium groups nor cationic N-substituted or N-unsubstituted iminium groups, said azo dyestuffs containing on the other hand at least one unsubstituted or substituted amino group, hydrazino group, amidino group or guanidino group capable of forming salts. The very dyeing process as such is carried out according to usual processing data for dyeing polyacrylonitriles in a slightly acid medium. Especially with the use of several of these dyestuffs for polychromic dyeing, such as trichromic dyeing, special advantages are obtained, insofar that even at cut-rate dyeing periods and for preparing light color shades, there are obtained even dyes with constant color shades, when using these dyestuffs having good migrating properties.

Abstract: Fiber material composed of acid-modified homopolymers or copolymers of acrylonitrile (PAC fibers) which has been obtained by a wet spinning process, has not been dried and is still in a swollen condition (gel form), can be dyed advantageously and in fast colors by means of soluble dyes, the molecule of which contains several groups, namely more than one quaternary grouping and/or a strongly basic grouping carrying no charge, which exert a basic action towards the acid groups of the fiber substance. The chromophore of this colorant can belong to the category of monoazo or diazo dyes, methine, azamethine or diazamethine dyes or naphthalactam dyes.In accordance with the invention, after substantially removing the non-aqueous spinning solvent by washing, the spun material, as a moist gel, is dyed continuously or discontinuously from an aqueous dyebath; the fibers can be stretched before the dye is applied, during the dyeing process itself or immediately afterwards.By virtue of their special nature, the dyes of the type designated above, which have a strong fixing action, produce optimum fixing rates when dyeing PAC gels and, in the subsequent production stages, do not cause any noticeable soiling, as a result of dye which has bled out, on components of machines and operating baths, such as stretching or after-treatment baths. Investigations of penetration of the fiber by the dye, of the fixing rate and of the resulting fastness properties, such as fastness to wet processing, have shown no disadvantages compared with conventional dyes.

Abstract: If highly concentrated aqueous solutions of azo dyes are prepared directly by diazotization and coupling reactions, appreciable difficulties generally result as a consequence of the fact that the diazotization and coupling reactions give rise to viscous phases which lead to stirring problems in the reaction apparatus used, which in turn results in an incomplete synthesis. The novel process for preparing concentrated aqueous dye solutions of an anionic dye in an aqueous medium overcomes this disadvantage by carrying out the diazotization of the aromatic amine diazo component and/or the coupling reaction between the diazonium salt and the coupling component in the presence of an auxiliary which exerts a viscosity-reducing effect on pasty phases. Examples of such auxiliaries are optionally alkyl-substituted naphthalenesulfonic acid-formaldehyde condensation products, ligninsulfonates, polyacrylates and copolymers of maleic anhydride and methacrylic acid or acrylic acid.

Abstract: A process for the direct preparation of pure thiazolazo compounds had been found with the use of a 2-aminothiazole as diazo or azo component in a coupling process wherein the 2-aminothiazole used therein is subjected to the usual coupling reaction, if used as diazocomponent after diazotation, without intermediate isolation after its preparation in known manner. This process avoids the preparation of the 2-aminothiazoles as starting compounds in its solid form and the expensive purification of these instable compounds and yields now very pure azo products.
