Abstract
The invention provides a disperse dye of the general formula <IMAGE> wherein X represents a chlorine or bromine atom, R1 represents an alkyl radical having from 1 to 4 carbon atoms, and R2 represents a methyl or ethyl group. These dyestuffs may be used for dyeing and printing synthetic fibre materials, especially polyester fibre materials. They are superior to analogous dyestuffs having an acetylamino group in place of the propionylamino group in that they give colourations of distinctly lower abrasion and with no deposits when applied onto packages. They have a good fastness to light and to waste gases and they also have a good build up. They may be used for fast dyeing processes and for colouring the polyester portion in polyester-wool blends.
Description
SPECIFICATION
Navy Blue Disperse Dyes, Dyeing Preparations and Compositions Containing them. Process for their Preparation and their use for the Dyeing or Printing of Synthetic fibre Materials
The present invention provides navy blue disperse dyes, preparations and compositions containing them, process for their preparation and their use for the dyeing or printing of synthetic fibre materials.
The disperse dyes have the general formula
where
X represents a chlorine or bromine atom,
R1 represents an alkyl radical having from 1 to 4 carbon atoms, and
R2 represents a methyl or ethyl group.
The dyestuff is generally in free form.
A composition of the invention comprises a mixture of one or more compounds of the general formula 1 and one or more other disperse dyes.
The dyestuff(s) are usually used in the form of a dyestuff preparation containing, as well as the dyestuff or dyestuffs, a suitable carrier.
Dyestuffs of the general formula
wherein X, R, and R2 have the meanings given for formula 1 are disclosed in Belgian Patent 634,032.
The dyestuffs of the invention differ from the dyestuffs of formula 2 in that they contain the propionylamino group instead of the acetylamino group. It was not to be expected therefore that the dyestuffs of the formula 1 would differ advantageously from the corresponding dyestuffs of the formula 2 containing the acetylamino group.
We have surprisingly found, however, that the dyestuffs of the invention are superior to an analogous dyestuff of the formula 2 in that they give colourations of distinctly lower abrasion and with substantially no deposits, when applied onto packages.
Dyestuffs of the invention are suitable for dyeing and printing synthetic fibre materials, especially polyester fibrous materials. They have a good fastness to light and to waste gases, a good build up and a low sensitivity to reduction and to variations in temperature during dyeing. They may be used for fast dyeing process and for colouring the polyester portion in polyester-wool blends.
The dyestuffs of the invention are, moreover, suitable for dyeing the above fibre materials from organic solvents.
The dyestuffs according to the invention may be prepared by coupling diazotized 2,4-dinitro-6chloroaniline or diazotized 2,4-dinitro-6-bromoaniline with a coupling component of the general formula
wherein R1 and R2 are as defined above. The reaction is suitably carried out in acid, aqueous solution in known manner.
A dyeing preparation containing one or more of the dyestuffs of the invention and optionally one or more other disperse dyes may be prepared by wet grinding of the dyestuff(s) with one or more dispersion agents, for example lignin sulphonates.
The following Examples illustrate the invention:
Example 1
217.5 Parts by weight of 2,4-dinitro-6-chloroaniline were introduced into 1,000 parts by weight of 96% sulphuric acid and dissolved while stirring. Next, 320 parts by weight of 40% nitrosylsulphuric acid were added, while maintaining the temperature at 30 to 350C by exterior cooling. Stirring at 30 to 350C was continued for two hours. After this period diazotization was complete. The resulting diazonium salt solution was added within 60 minutes to a stirred solution of 4,000 parts by weight of water, 6,000 parts by weight of ice, 1,000 parts by weight of giacial acetic acid and 280 parts by weight of 2-ethylamino-4-propionylamino- 1 ,B-methoxyethoxybenzene.
Further quantities of ice were added during this addition to prevent a temperature rise above +50C. Stirring was continued for 3 hours, and the dyestuff formed was suction-filtered and washed with water until free from acid. Drying gave 410 parts by weight of the dyestuff which corresponds to a yield of 83% of the theoretical yield. The dyestuff had the formula
When applied onto polyester fibres dyeing compositions of this dyestuff provided deep navy blue colourations.
Examples 2 to 17
The dyestuffs listed in the following Table were prepared in analogous manner. They have the formula
wherein X, R1 and R2 are as defined above. When applied onto polyester fibre material these dyestuffs, too, provided deep, navy blue colourations.
