Abstract: Developing dyes are especially easily produced by using preparations containing molar amounts of diazo or coupling components per weight or volume unit or a multiple or a fraction thereof in simple numerical ratios. Since the diazo component is the free finely dispersed amine these preparations are stable and allow the reaction of stoichiometric amounts. Thus, multicolor effects are feasible which hitherto could not be obtained at all or with difficulties only.

Abstract: Process for printing textile mixed fabrics of polyester and cellulose fibers with printing pastes containing coupling components dissolved in an alkaline medium, sodium nitrite, diazotizable primary aromatic amines and optionally disperse dyestuffs, in which process the amines are used as a solution or in the form of an aqueous fine dispersion with a particle size of less than 0.03 mm and are selected in a manner that they are practically non-volatile at the drying temperatures and exhibit minimum basicity with the pK.sub.a being 2.

Abstract: Process for printing textile cellulose fiber fabrics with printing pastes containing coupling components dissolved in an alkaline medium, sodium nitrite and diazotizable primary aromatic amines, in which process the amines are used as a solution or in the form of an aqueous fine dispersion with a particle size of less than 0.03 mm and are selected in a manner such that they are paractically non-volatile under at the drying temperatures and show a minimum basicity degree with the pK.sub.a being 2.2 or more, developing the water-insoluble azo dyestuffs on the fiber by diazotizing the amines and coupling the diazonium compound formed with the coupling components following the drying of the printing pastes applied by a treatment of the printed fabrics at room temperature with an aqueous developing bath containing formic acid, and completing the coupling without a previous intermediate drying of the fabric, however, optionally following an air passage, by a short-time steaming with saturated steam.

Abstract: Azo developing dyestuffs are produced by diazotizing on the fiber a mono- to tetramine derived from a metal-containing or metal-free phthalocyanine, the amino group(s) being bound to a phenyl or naphthyl group (which may be substituted) which is linked via a bridge member to the phthalocyanine which may further contain up to 3 optionally substituted sulfon amide groups and up to 3 sulfo groups, and coupling said diazotized amino onto azoic coupling components usual for preparing developing dyestuffs.

Abstract: A process for the fixation of organic dyestuffs on materials having a fibrous structure had been found, in which an organic dyestuff containing one or several groups of the formula (I) ##STR1## wherein R.sup.1, R.sup.2, R.sup.3 and R.sup.4 each represent a non-ionic, anionic or cationic substituent, with the exception of a primary or secondary amino group or the salts thereof, is applied in dissolved form onto said materials and subsequently subjected to the action of nitrous acid. The process yields fiber materials on which active substances, such as dyestuffs, brighteners, mothproofing agents, water-repellent agents, etc., are fixed fast; the novel process is especially and advantageously suitable in combination with the ice-color technique.

Abstract: Cellulosic material is printed with a paste containing the alkaline solution of a coupler, the dispersion of a diazotable aromatic amine, a nitrite and a thickener and the dyestuff is developed on the fiber by acidic steaming or by adding solutions of organic acids and steaming or drying.

Abstract: Cellulosic material is printed with a paste containing the alkaline solution of a coupler, the dispersion of a diazotable aromatic amine, a nitrite and a thickener, and the dyestuff is developed on the fiber by adding solutions of organic acids and, after a short air passage, contacting the dyeing or print with an alkaline agent.

Abstract: Continuous dyeing and printing of cellulose fibre material by impregnating the material with a 2-hydroxy-naphthalene-3-carboxylic acid phenyl amide, alkali and nitrite, by crosspadding or over-printing with a dispersion or emulsion of a 4-amino-diphenyl amine as well as acid or acidic salt, and bringing about the development of the dyestuff by drying the fiber material and/or exposing it to sodium carbonate.

Abstract: A process for the printing of cellulose containing textiles or textiles consisting completely of cellulose with water-insoluble azo dyestuffs produced on the fiber, which comprises printing the material previously impregnated with alkaline liquors of .beta.-hydroxy-naphthoic acid arylamides or acetoacetic acid arylamides and sodium nitrite with a printing paste containing an aqueous dispersion of an amine suitable for ice color dyeing having a maximum grain size of 0.03 mm or less, acidifiers and a thickening, and finishing the prints after drying in usual manner by washing, soaping and rinsing.

Abstract: Process for the continuous dyeing of polyester fiber/cellulose blends with disperse dyestuffs and water-insoluble azo developing dyestuffs by padding the fibrous material with an aqueous solution of at least one ice-color coupling component, an alkaline agent and an alkali metal nitrite, then cross-padding the material so impregnated with a second aqueous bath of room temperature which contains at least one diazotizable amine, at least one thermosolable disperse dyestuff and an acidifier, and finally successively promoting the formation of the azo dyestuff by diazotizing and coupling as well as fixing the disperse dyestuff with the aid of elevated temperature.
