• This invention relates to fiber- reactive disazo compounds and a process for their production. These compounds are suitable for use as fiber-reactive dyestuffs in any conventional dyeing or printing processes.
• X. is -SO Z
• ⁇ 2 is -NRQ
• R is hydrogen, C ⁇ - alkyl or
• Y are -OSO 3 H, -Cl and -SSO 3 H, especially preferred is -OSO3H.
• R is hydrogen. More preferred compounds of formula (I) correspond to formula (la)
• the -SO H group is in 3 position.
• the -SO 2 Z group is in 4 position.
• the cation associated with the sulpho groups and any carboxy group is not critical and may be any one of those non-chromophoric cations conventional in the field of fiber-reactive dyes provided that the corresponding salts are water- soluble.
• Examples of such cations are alkali metal cations and unsubstituted and substituted ammonium cations, e ⁇ ., lithium, sodium, potassium, ammonium, mono-, di- and tri- ethanolammonium.
• the preferred cations are the alkali metal cations and ammonium, with sodium and potassium being the most preferred.
• the cations of the sulpho groups can be the same or different, e.g., they can also be a mixture of the above mentioned cations meaning that the compound of formula (I) can be in a mixed salt form.
• the invention further provides a process for the preparation of compounds of formula (I) or mixtures thereof which is characterized by coupling a compound of formula (II)
• the condensation reaction of the amino compound with 2,4,6-t ⁇ fiuoropy ⁇ m ⁇ d ⁇ ne or 5-chloro- 2,4,6-t ⁇ fluoropy ⁇ m ⁇ d ⁇ ne is carried out in a manner known per se, preferably at 0° to 50°C, more preferably at 10° to 20°C, and at a pH of about 5 - 7

• the compounds of formula (I) may be isolated in accordance with known methods, for example, by conventional salting out with an alkali metal salt, filtering and drying optionally in vacuum and at slightly elevated temperatures.
• a compound of formula (I) is obtained in free acid or preferably salt form or even mixed salt form containing, for example, one or more of the above mentioned cations. It may be converted from free acid to a salt form or mixture of salt forms or vice versa or from one salt form to another by conventional means.
• this mixture is preferred to use as it is without resorting to the isolation of a single isomer for use. but should this be desired it can be readily achieved by conventional methods.

• Dyeing or printing is effected in accordance with known methods conventional in the fiber- reactive dyestuff field.
• the exhaust dyeing method is used at temperatures within the range of 30° to 100°C. particularly at 40° - 80°C, respectively, whereby a liquor to goods ratio of 6: 1 to 30: 1 is used and more preferably of 10: 1 to 20: 1.
• the compounds of this invention have good compatibility with known fiber-reactive dyes; they may be applied alone or in combination with appropriate fiber-reactive dyestuffs of the same class having analogous dyeing properties such as common fastness properties and the extent of ability to exhaust from the dyebath onto fiber.
• the dyeings obtained with such combination mixtures have good fastness properties and are comparable to those obtained with a single dyestuff.
• the compounds of formula (I) give good exhaust and fixation yields when used as dyestuffs. Moreover, any unfixed compound is easily washed off the substrate.
• the dyeings and prints derived from the compounds of formula (I) exhibit good light fastness and good wet fastness properties such as wash, water, seawater and sweat fastness. They also exhibit good resistance to oxidation agents such as chlorinated water, hydrochloride bleach, peroxide bleach and perborate- containing washing detergents.
• the new dyestuffs can also be used in the preparation of printing inks which are suitable for the ink jet process.
• the dyeings have excellent fastnesses whereby the unfixed dyestuff can easily be washed out, even from deep dyeings.
• Example 1 If the solution of the dyestuff obtained in Example 1 is treated at pH 10 with 400 parts of a 10% sodium hydroxide solution, the dyestuff in its vinylsulfonic form is obtained which corresponds to the formula

• Example 1 0.3 Part of the dyestuff of Example 1 is dissolved in 100 parts of demineralized water and 3g Glauber's salt (calcined) is added. The dyebath is heated to 50°C, then 10 parts of cotton fabric (bleached) are added. After 30 minutes at 50°C, 0.4 part of sodium carbonate (calcined) is added to the bath. During the addition of sodium carbonate the temperature is kept at 50°C. Subsequently, the dyebath is heated to 60°C, and dyeing is effected for a further one hour at 60°C.
• the dyed fabric is then rinsed with running cold water for 3 minutes and afterwards with running hot water for a further 3 minutes.
