The novel cationic dyes according to the invention are greenish-yellow dyes.
The novel cationic dyes of the formula I are used for dyeing and, with the addition of binders and solvents, for printing materials which are dyeable with cationic dyes, particularly textile materials consisting for example advantageously of homo- or copolymers of acrylo-nitrile; or synthetic polyamides or polyesters which are modified by acid groups, Furthermore, the novel cationic dyes are also used for dyeing wet tow, plastics materials, leather and paper. Dyeing is preferably performed from an aqueous, neutral or acid medium by the exhaust process, optionally under pressure, or by the continuous process. The textile material can be in the widest variety of forms, for example in the form of fibres, filaments, fabrics, knitwear, piece goods and finished articles, such as shirts and pullovers.
Finally, the novel dyes of the formula I can be used also in the transfer printing process.
There can be produced by application of the dyes according to the invention very deep, level, greenish-yellow dyes and printings which are characterised by very good general fastness properties, such as very good fastness to light, decatising, washing and perspiration.
Those dyes of the formula I which have good solubility in organic solvents, such as perchloro-ethylene, are also suitable for dyeing the textile materials mentioned, or for dyeing, for example, plastics materials, from organic media.
The novel cationic dyes of the formula I are produced for example by condensing an aldehyde of the formula II
with an amine of the formula Ill
wherein the symbols R1, R2, B3, B4, Rs, B6 and R7 are as defined under the formula I, in the presence of an acid
HA, in which A is the radical of an anion; or by condensing an aldehyde of the formula II with an amine of the formula III in an organic solvent in the presence of dehydrating agents.
The starting compound of the formula II is known, and some of the starting compounds of the formula III are known and can be produced by analog processes for the known benzomorpholines (for example Chem.
Berichte Vol. 30, p. 1634ff; Vol. 55, p. 3821; Chem. Zentralblatt, p. 525 (1898), and U.S. Patent Specification No.2,448,869).
The compounds of the formula II are for example the following
The following are listed as examples of compounds of the formula Ill: benzomorpholine, 3-phenyl-benzomorpholine, 3,7-dimethyl-benzomorpholine, 3-phenyl-6-methyi- benzomorpholine, 7-methyl-benzomorpholine, 6-methyl-benzomorpholine, 8-methyl-benzomorpholine, 6- chloro-benzomorpholine, 6-methoxy-benzomorpholine, 7-chloro-benzomorpholine, 7-methoxy- benzomorphoiine, 6,8-dimethyl-benzomorpholine, 6,7-dimethyl-benzomorpholine, 3-methyl benzomorpholine, 3-ethyl-benzomorpholine, 3-ethyl-6-methyl-benzomorpholine, 3-propyl- benzomorpholine, 3-[p-methyl]-phenyl--benzo-morpholine, 3- [p-chloro]-phenyl-7-methyl benzomorpholine,3-[p-methoxy]-phenyl-7-methyl-benzomorpholine,3-[m.p-dimethyl]-phenyl-7-methyl- benzomorpholine, and 3-phenyl-7-methyl-benzomorpholine.
The condensation reaction of the aldehyde of the formula II with the amine of the formula III is performed in a known manner, for example in an aqueous medium at a temperature of about 0 to 1000C, in the presence of an acid HA. This acid is an organic acid, such as acetic acid or arylsulfonic acid, particularly benzenesulfonic acid; or it is an inorganic acid, such as hydrochloric acid, sulfuric acid or phosphoric acid.
If the reaction is performed in organic solvents with dehydrating agents, suitable solvents are aprotic organic solvents: for example aliphatic, optionally chlorinated, hydrocarbons such as cyclohexane, methylene chloride, chloroform or tetrachloroethylene; or aromatic, optionally chlorinated, hydrocarbons such as toluene, chlorobenzene or dichlorobenzene, as well as ketones and ethers; and suitable dehydrating agents are for example phosphorus oxychloride and thionyl chloride.
After the condensation reaction, the novel cationic dyes are separated from the reaction medium and dried. If it is desired or is necessary, it is possible to exchange in the dyes of the formula I the anion A for another anion.
In the following Examples, the term 'parts' denotes parts by weight, percentages are given as per cent by weight, and the temperature values in degrees Centigrade.
Example 1
10 parts of 1 ,3,3-flimethyl-2-methyleneindoline-co-aldehyde and 6.7 parts of benzomorpholine are dissolved in 30 parts of methanol. There are then added 2.5 parts of formic acid, and the reaction solution is held at 40 - 45 " for 2 hours. The methanol is subsequently distilled off; the residue consisting of 18 g of crude product is afterwards dissolved in 100 parts of 1 N acetic acid at 50", the solution is clarified and then cooled to room temperature. To the dye solution are added 10 parts of aqueous hydrochloric acid (30%) and 20 parts of sodium chloride, whereupon the dye salt of the formula
precipitates in crystalline form.This is filtered off and dried to yield 6.5 parts of a very pure cationic dye which produces on polyacrylonitrile materials pure greenish-yellow shades having a high degree of fastness to light.
Example 2
6 parts of 1,3,3-trimethyl-2-methyleneindoline-co-aldehyde and 6.3 parts of 3-phenyl-benzomorpholine are mixed with 30 parts of 1 N sulfuric acid, and held at 70-75 for4 hours. There are added 200 parts of 1 N acetic acid and 200 parts of toluene; the phases are then separated and, by the addition of 10 parts of sodium chloride to the aqueous phase, the dye salt of the formula
is precipitated in the form of a crystalline product. It is filtered off and dried in vacuo at 600 to obtain 6.3 parts of a yellow cationic dye which dyes polyacrylonitrile fibres in very pure greenish-yellow shades having excellent fastness properties.
If in the above Example the sulfuric acid is replaced by corresponding amounts of hydrochloric acid or phosphoric acid, an analogous cationic dye is obtained.
Example 3 6 parts of 1 ,3,3-trimethyl-2-methyleneindoline-o-ald and and 4.9 parts of 3,7-dimethyl-benzomorpholine are dissolved in 50 parts of chloroform. There are then added dropwise with stirring, within 5 minutes, 6 parts of phosphorus oxytrichloride, with the reaction temperature rising to 50"; the temperature is subsequently held at 60" for a further 2 hours, and 10 parts of a 40% aqueous sodium acetate solution and 50 parts of water are then added. The chloroform is afterwards distilled off, and the residue is dissolved in 10 parts of acetic acid and 250 parts of water at 70". The dye solution is clarified by filtration and cooled. The dye salt of the formula
precipitates, and is filtered off and dried.The yield is 8.2 parts of the yellow cationic cye which is excellently suitable for dyeing polyacrylonitrile. If there are used, instead of phosphorus oxytrichloride, corresponding amounts of thionyl chloride, the same cationic dye having equally good properties is obtained.
By using, instead of 6 parts of 1,3,3-trimethyl-2-methyleneindoline-o)-aldehyde, equivalent parts of 1 -ethyl-3,3-dimethyl-2-methyleneindoline-co-aldehyde or of 1 -benzyl-3,3-dimethyl-2.methyleneindoline-co- aldehyde or of 1-allyl-3,3-dimethyl-2-methyleneindoline-co-aldehyde, with otherwise the same procedure, there are obtained greenish-yellow dyes having equally good properties.
With an analogous procedure and with appropriate variation of the starting materials, there are obtained the cationic dyes which are listed in the following Table and which correspond to the formula
which dye polyacrylonitrile materials in greenish-yellow shades;

Example 47
5 g of the cationic dye produced according to Example 1 is stirred to a paste with 2 g of 40% acetic acid, and taken into solution by the addition of 4000 g of hot water. There are subsequently added 1 g of sodium acetate and 2 g of an addition product of 15 to 20 equivalents of ethylene oxide with N-octadecyidiethylenetriamine, which product has been quaternised with dimethyl-sulfate; and 100 g of polyacrylonitrile fabric is then introduced at 60". The bath is heated within 30 minutes to 100 , and the material is dyed at boiling temperature for 90 minutes. The liquor is afterwards allowed to cool in the course of 30 minutes to 60 , and the dyed material is then removed, and finally rinsed with lukewarm water and with cold water.
A pure greenish-yellow polyacrylonitrile dyeing having fastness to light is obtained.
Example 48
A polyacrylonitrile copolymer consisting of 93% of acrylonitrile and 7% of vinyl acetate is dissolved in dimethylacetamide to give a 15% solution. The spinning solution is then extruded into a spinning bath which is made up of 40% of dimethylacetamide and 60% of water. The resulting tow is subsequently drawn by known methods, and freed from dimethylacetamide by rinsing with hot and cold water.
This wet tow is dyed by immersion in an aqueous bath at 42" of the following composition:
9 g of dye according to Example 1 per litre,
pH-value 4.5 with acetic acid.
The contact time 'tow/dye liquor' is 2 seconds. The excess dye liquor is subsequently squeezed out, and the tow is fed into the dryer. A tow dyed in a greenish-yellow shade and having good fastness properties is obtained.
