Definitions

• the invention relates to carriers, their preparations and processes for dyeing polyester materials with disperse dyes in the presence of these carriers.
• Known carriers used in textile practice in dyeing polyester include halogenobenzenes, halogen toluenes, N-alkylphthalimides, aromatic carboxylic esters, methylnaphthalene, diphenyl, diphenyl ether, naphthol ether, phenol ether and oxydiphenyls.
• these connections have disadvantages. All compounds, with the exception of the N-alkylphthalimides, have a strong intrinsic odor. Methylnaphthalene and the oxydiphenyls adversely affect the lightfastness of the dyeings. Diphenyl ether has the disadvantage that its carrier activity depends strongly on the constitution of the disperse dye used and therefore often no reproducible colorations are obtained.
• N-alkylphthalimides show a sharp drop in the dyeing temperature below 98 ° C. Carrier effect, which limits their use in higher regions, where this temperature is not reached with open dyeing machines. Phthalic acid esters and benzoic acid esters have only a limited carrier effect and a limited leveling capacity and therefore require high amounts.
• the object of the present invention is to provide highly effective, halogen-free carriers which bring about the most level possible coloring with a small amount used.
• the dyeing achieved should meet high authenticity standards, and when dyeing mixed fibers, the accompanying fiber should not be soiled.
• the carriers according to the invention are a mixture of N-alkylphthalimides (I) and compounds of the general formula wherein R is C1-C7 alkyl; Phenyl, benzyl or phenylethyl, which can be substituted by C1-C4-alkyl, C1-C4-alkoxy or C1-C4-alkoxycarbonyl.
• R1 is hydrogen, C1-C4-alkyl, C1-C4-alkylcarbonyloxy, hydroxy or C1-C4-alkoxycarbonyl, m 0 or 1, n is 0 or 1, where m and n are not simultaneously 0, contain, is solved.
• These mixtures of carrier active substances show a synergistic increase in the color-accelerating effect compared to the individual components.
• the preferred weight ratio of N-alkylphthalimides (I) to the compounds (II) is 0.5-12: 1.
• the carrier mixtures according to the invention are water-insoluble, they are preferably added to the dyeing liquors in the form of preparations which contain emulsifiers or dispersants and, if appropriate, solvents.
• N-alkylphthalimides (I) are understood to mean, in particular, straight-chain or branched alkyl radicals (C1-C6) on the nitrogen-substituted phthalimides or mixtures thereof which, for. B. can be prepared by the reaction of phthalic anhydride or phthalic acid esters with amines.
• the carriers can therefore contain phthalic acid amides and esters due to the manufacturing process.
• Examples of the compounds (II) are aromatic monocarboxylic acid esters (e.g. esters of benzoic acid, methylbenzoic acid, salicylic acid), dicarboxylic acid esters (e.g. esters of terephthalic acid or phthalic acid), carbonates (e.g. diphenyl carbonate) and ethers (e.g. B. diphenyl ether or ditolyether).

• the disperse dyes used for dyeing are the disperse dyes usually used for dyeing polyesters, as described, for example, in "Color Index” Vol. 2, pp. 2483-2741, 3rd edition (1971).
• the dyeing in the presence of the carriers according to the invention is carried out according to the batchwise methods customary for dyeing with disperse dyes; the usual process operating at 98 ° C. and the high-temperature process may be mentioned as such.
• the carrier blends according to the invention are also suitable for dyeing polyester / wool and polyester / cotton blended fabrics, because when they are used the soiling of the wool and cotton content is avoided by the disperse dyes.
• the dyeing can be carried out at temperatures of 90-140 ° C, the preferred industrial application being at 90-150 ° C.
• An additional advantage of the carrier settings described is the very good effectiveness below the cooking temperature, which pure N-alkylphthalimide carriers do not show, e.g. B. at 95 ° C, which is often not exceeded under practical conditions with open dyeing machines.
• the amounts of the mixture of carriers (I) and (II) required to carry out the dyeing can easily be determined from case to case by preliminary tests. In general, amounts of 1 to 7 g per liter of dye liquor have proven themselves in the usual liquor ratios of 1: 5 to 1:40.
