The dyes of this invention impart red to blue shades on natural and synthetic fibers and exhibit improvements over such dyes as disclosed in U.S. Pat. No. 2,805,218 and British Pat. No. 1,021,399 in one or more properties such as fastness to light, ozone, chlorine, oxides of nitrogen, washing, sublimation, heat disintegration, perspiration, and crocking, leveling, transfer, exhaustion, build, pH stability, and resistance to blooming.

The intermediate compounds used in this invention are prepared according to procedures well known to the art. The present dyes are readily prepared, for example, by reacting the acetyl group of the intermediate azo compound, which itself is a dye, with benzaldehyde or a substituted benzaldehyde in acetic acid with concentrated sulphuric acid as catalyst. The acetyl dye is thus converted to a cinnamoyl substituted dye in high yield. The water-solubilizing group may be the substituent on the benzaldehyde or it may be introduced into the cinnamoyl dye at a later stage by known methods. For example, a hydroxy group in either the diazonium component or the coupling component could be reacted with sulphuric acid and then with MOH to give the --OSO.sub.3 M group. Alternatively a chloroalkyl group in the dye could be reacted with K.sub.2 SO.sub.3 to give the --CH.sub.2 SO.sub.3 K group. Also, sulphonation of an aromatic ring or other reactive group in the dye with a sulphonating agent such as H.sub.2 SO.sub.4 or Cl--SO.sub.3 H would give the solubilizing group. Such groups could also be present in the coupling component prior to diazotisation and coupling.

The following Preparations, Example and tables will illustrate the making and use of intermediates for the synthesis of dyes of the present invention.

PREPARATION A

.alpha.-(N-Ethylanilino)-Toluenesulfonic Acid

To 30.0 g. of 100% sulfuric acid is added N-benzyl-N-ethylaniline (30.0 g.) dropwise below about 50.degree. C. To this solution is added, at 50.degree.-60.degree. C., 60% oleum (30.0 g.) with good stirring. The mixture is stirred and heated at about 60.degree. C. for three hours and then drowned into 200 ml. of water. The free sulfonic acid (Coupler 1) which is mostly the meta isomer with a small amount of para, precipitates on standing and is collected by filtration, washed with water, and dried. N-Benzylanilines containing groups such as alkyl, alkoxy, and halogen in the ortho, meta, or para positions of the benzyl group may also be sulfonated by this procedure. The exact location of the sulfonic acid group in these cases is often not known and mixtures usually are produced.

Aromatic amines which contain N-aralkyl groups and which are sulfonated by the above procedure to give Couplers 2 to 11 are listed below.

PREPARATION B

Diazotization and Coupling of 2-Amino-6-Acetylbenzothiazole

To 150 g. of 60% acetic acid containing 10 g. of concentrated H.sub.2 SO.sub.4 is added 0.055 m. of 2-amino-6-acetylbenzothiazole at room temperature. The solution is cooled to -5.degree. C., and a solution of 3.6 g. NaNO.sub.2 in 20 ml. of concentrated H.sub.2 SO.sub.4 is added below 0.degree. C. The reaction mixture is stirred at -5.degree. to 0.degree. C. for 1.5 hours. Each of the Couplers 1 to 11.0 (0.005 m.) listed is added to water, or a 0.005 mole aliquot of the coupler in dilute sulfuric acid is added to water, and cooled in an ice bath.

To each chilled coupler is added a 0.005 mole aliquot of the diazonium solution. The coupling mixture is treated with enough potassium acetate to neutralize the mineral acid. Water is added to the coupling mixture to a total volume of about 200 ml. and the dyes collected by filtration, washed with 10% KCl solution, and dried in air. The dyes usually are admixed with about an equal weight of K.sub.2 SO.sub.4 and are used for dyeing without further purification to produce red shades on polyamides. These dyes are intermediates for the preparation of dyes of the present invention.

PREPARATION C

Diazotization and Coupling of 3-Amino-5-acetyl-2,1-benzisothiazole

To 25 ml. of concentrated H.sub.2 SO.sub.4 is added 3.6 g. of NaNO.sub.2 portionwise below 80.degree. C. The solution is cooled and 50 ml. of 1:5 acid (1 part propionic, 5 parts acetic acid) is added below 20.degree. C. The mixture is further cooled and 3-amino-5-acetyl-2,1-benzisothiazole 0.055 m. is added, followed by 50 ml. of 1:5 acid, all at 0.degree.-5.degree. C. The diazonium, after stirring at 0.degree.-5.degree. C. for 1 hr., is coupled to each of the Couplers 1-11 in a similar manner as above to produce violet to reddish blue dyes for polyamides.

PREPARATION D

Sulfonation of Dye Containing an N-(Aralkylamino) Group

The dye from 2-amino-5-acetyl-2,1-benzisothiazole and N-benzyl-N-ethylaniline (2.0 g.) is added portionwise to 15 ml. of concentrated H.sub.2 SO.sub.4 over 20 min., allowing the temperature to rise to 30.degree. C. The reaction mixture is then heated at 70.degree. C., and when the reaction is completed as evidenced by thin-layer chromatography, the reaction mixture is drowned on ice-water mixture, and 50% NaOH is added until the pH is about 7. The dye is collected by filtration, washed with water, and dried in air. The dye has the structure ##STR4##

EXAMPLE

Final Dye Preparation ##STR5##

A mixture of compound (I) (2 g.), benzaldehyde (1.5 g.), acetic acid (25 ml.) and concentrated sulphuric acid (5 ml.) was stirred at 100.degree. C. for 1.5 hours. The reaction mixture was poured into cold water and the produce dye (II) filtered off, washed with water and dried. Compound (I) had previously been prepared by diazotising the known 2-amino-6-acetylbenzothiazole and coupling with N,N-diethyl-m-toluidine by known procedures. The dye (II) when applied to nylon, polyester and other synthetic fibres by known techniques gives bright, bluish red shades with good dyeing and fastness properties.

By using the methods described hereinabove, the following dyes are obtained.
