    Abstract: Process for preparing dyeings and prints which are fast to light and not capable of being affected by dyeing accelerators (carriers), on synthetic fibrous material, preferably linear polyester fibers, with insoluble dyestuffs, by subjecting the dyeings and prints prepared in the usual manner on textile articles with aqueous preparations of said dyestuffs with the aid of carriers to an aftertreatment in an organic solvent or solvent mixture.

    Abstract: Local brightening, 'white discharging' and 'colour discharging' of dyeings on textiles (already dyed but the dye not necessarily fixed) comprises treatment with a printing paste contg. apart from usual thickeners, auxiliaries and water, also an auxiliary (I) which dissolves the dye applied at elevated temp. but does not damage the material under thermosol conditions. The printed material is then heated, esp. by steaming or dry heating. Esp. the method is applied to polyester dyed with disperse dyes or to blends of natural and synthetic fibres (esp. cellulose-polyester) dyed with disperse dyes, vat dyes, their leuco esters or development dyes. (I) is pref. an ethoxylated fatty alcohol, fatty acid or alkylphenol, and the paste can also contain other discharge agents or auxiliaries.. Uniformly bright patterns are achieved on intensely coloured backgrounds. The method can be applied to a wider range of disperse dyes than known processes.

    Abstract: PROCESS FOR DYEING SYNTHETIC FIBROUS MATERIALS FROM ORGANIC SOLVENTS Process for the continuous dyeing of textile materials which consist of, or contain synthetic fibres from organic solvents, wherein the said textile materials are impregnated with an organic dyeing liquor which contains at least one dyestuff of the formula in which R represents alkyl from 1 to 8 carbon atoms, X1 and X2 each represents hydrogen, chlorine, bromine, lower alkyl, lower alkoxy, trifluoromethyl or nitro, R1 represents hydrogen, chlorine, bromine, alkyl from 1 to 4 carbon atoms, alkoxy from 1 to 4 carbon atoms, R2 represents hydrogen, chlorine, bromine, alkyl from 1 to 4 carbon atoms, alkoxy from 1 to 4 carbon atoms, acetylamino or benzoylamino, R3 and R4 each represents hydrogen, alkyl, hydroxyalkyl, cyanoalkyl, alkoxyalkyl, alkylcarbonylalkyl, alkylcarbonyl-hydroxyalkyl, alkoxycarbonylalkyl, phenyl or phenylalkyl, alkyl and alkoxy each containing from 1 to 4 carbon atoms, and subsequently exposed to a heat treatment.

    Abstract: In the process for the pad-dyeing or printing of materials consisting of, or containing, polyester or polyamide fibers or filaments, in which process the materials are padded or printed in common manner with aqueous baths or printing pastes of disperse dyestuffs, and the dyestuffs are subsequently fixed by the action of liquid or gaseous methylene chloride or both of the said phases of methylene chloride, the improvement that dyestuffs of the general formula in which R is an alkoxy group of from 1 to 3 carbon atoms, the group in which n stands for an integer of from 2 to 6, are used.
