Abstract: A process for printing and dyeing sheetlike fiber materials with anionic dyes comprisesa) first applying to the sheetlike fiber material an aqueous solution containing a fixing alkali and a compound which contains a primary, secondary or tertiary amino group or a quaternary ammonium group, which may each also be part of a heterocycle, by using a printing process, thenb) subjecting the sheetlike fiber material to a fixing treatment to modify the sheetlike fiber material, and finally and optionallyc) dyeing the modified sheetlike fiber material one or more times by a customary exhaust or padding method.

Abstract: Process and use of reactive disperse dyes for dyeing and printing aminated, textile cotton and cotton-polyester blend fabricsHydroxyl-containing materials, in particular fiber materials, such as cellulose fiber materials, which have been modified with an amino-containing compound are dyed as such or in blend with polyester fibers with the aid of a fiber-reactive disperse dye in an aqueous, low-electrolyte or completely electrolyte-free medium and in the absence of an alkaline or alkali-donating agent at a temperature of between 100.degree. and 210.degree. C. Not only the modified cellulose-containing material but also the polyester material can be dyed in one and the same dyeing process with one and the same fiber reactive disperse dye. A uniform overall dyeing not only for modified hydroxyl-containing material but also for polyester material is obtained.

Abstract: Imine dyes useful in photographic materials have the formula ##STR1## wherein R.sup.1, E.sup.1, E.sup.2, L.sup.1, L.sup.2, L.sup.3,D and m are defined as in the specification.Solid particle dispersions of dyes of formula (I) that contain at least one base-ionizable functional group such as carboxy, sulfonamido, or sulfamoyl are useful as filter dyes in photographic elements.

Abstract: A process for dyeing a mixed fibre substrate with at least one disperse dye and at least one metal complex dye selected from direct dyes and reactive dyes characterized in that dyeing is carried out in the presence of a compound of formula I ##STR1## in which X is --S--, --O--, or --NH--;R.sub.1 is hydrogen, --OH or C.sub.1-4 alkyl; andR.sub.2 is hydrogen, NH.sub.4 or an alkali metal (such as Na or K).

Abstract: Aramid fabrics treated with N-cyclohexyl-2-pyrrolidone prior to or simultaneously with aqueous print pastes promote fabric printability and produces good coloration. Saturated steam or superheated steam at a temperature of at least 100.degree. C. permeates and fixes the dye inside of the aramid fibers. Print pastes containing N-cyclohexyl-2-pyrrolidone, dye and thickener are also described.

Abstract: Aramid and aramid-blend fabrics are dyed or flame-retardant treated or both dyed and flame-retardant treated using conventional heat dyeing equipment. Octylpyrrolidones, tributyl phosphine oxide and mixtures of N-cyclohexyl-2-pyrrolidone with available dye carriers are used as diffusion-promoting agents for dyes, flame retardant agents or both. Odor-free, flame resistant, colored or colored and highly flame resistant products result.

Abstract: Poly(m-phenyleneisophthalamide) fabrics containing N-cyclohexyl-2-pyrrolidone on them are printed with a print paste. Print pastes containing N-cyclohexyl-2-pyrrolidone are also described.

Abstract: Aramid and aramid-blend fabrics are dyed and optionally flame-retardant treated using conventional pressure and heat dyeing equipment. Odor-free, colored or colored and highly flame resistant products result.

Abstract: Aramid fibers, polybenzimidazole fibers or blends of aramid and polybenzimidazole fibers are rendered flame resistant by a flame retardant introduced into the fibers by a polar organic swelling agent such as DMSO. Dyed or undyed fibers so treated exhibit substantially improved flame resistance as compared with untreated fibers.

Abstract: When silk fabrics, pre-treated with swelling agents, are printed by heat transfer techniques, the fabric will yellow. The invention eliminates yellowing by pre-treating said silk fabrics with a liquid or solid impregnating agent, dissolved or dispersed in water, then drying the fabric, and adding before, during or after the pre-treating an optical brightening agent of the type normally used for polyester.The impregnating agent can alternatively be applied to the fabric in a water-free condition before or during dyestuff transfer, and an optical brightener may be added.It is further contemplated to use easily migrating dyestuffs which are transferred to the fabric at relatively very low temperatures, and to avoid dyestuff migration by pre-treating the silk fabric with solid impregnating agents.All these techniques produce deep and brilliant shades; the prints have excellent fastnesses.

Abstract: Methods of rendering water-soluble dyes insoluble comprise contacting a polymer containing X-alkyl-2-oxazolidinone with the desired dye or dyes. The essentially water-insoluble pigments so prepared are useful in a wide variety of uses and, in particular, in coloring soaps, toothpaste, etc.

Abstract: Process for dyeing textile materials of cellulose, by means of direct dyestuffs or reactive dyestuffs, by padding with aqueous dyeing liquors which contain cyclic carboxylic acid amides of the formula ##STR1## in which R represents a hydrogen atom, a C.sub.1 -C.sub.4 -alkyl radical or a C.sub.1 -C.sub.4 -hydroxyalkyl radical andA represents an alkylene radical required to complete a five-membered to seven-membered ring system and optionally substituted by halogen, C.sub.1 -C.sub.4 -alkyl or C.sub.1 -C.sub.4 -hydroxyalkyl andn is 0 or 1,and, optionally, glycol compounds of the formula ##STR2## in which R' and R"' independently of one another represent hydrogen, a C.sub.1 -C.sub.5 -alkyl group or an acetyl group,R" represents hydrogen or methyl,n represents a number from 0 to 2 andX represents an oxygen atom or a sulphur atom, and fixing of the dyestuffs.

Abstract: Mixture of optical brighteners consisting of from 0.5 to 0.95 part by weight of a brightener of the series of the benzoxazolyl-stilbenes and of from 0.95 to 0.05 part by weight of a brightener of the series of the aryltriazoles.
