Description:
FIELD OF THE INVENTION 
     The present invention relates to new water-soluble trisazo compounds and colored articles therefrom. 
     PRIOR ARTS 
     Among various color recording methods, one typical method is the recording method by means of ink jet printers wherein ink droplets are produced and deposit on various materials to be recorded such as papers, films and fabrics so that recordings are effected. This method has advantages that it is silent since materials to be recorded are not contacted with a recording head and that miniaturization, speeding up and color printing can be easily achieved. Thus, it has recently come into wide use and it is expected to greatly spread in future. 
     As inks for pens, felt-tip pens and the like as well as inks for ink jet printers, aqueous inks comprising water-soluble dyes dissolved in aqueous media are used. Generally, the aqueous inks comprise water-soluble organic solvents in order to prevent the inks from clogging in nibs and ink delivery nozzles. These inks should meet the requirements that they can form images having a high optical density, that they do not clog nibs and ink delivery nozzles, that they are easily dried on materials to be recorded, that they hardly blot and that they have excellent storage stability. In addition, images therefrom should have sufficient light and water resistances. 
     Various inks having different hues are prepared from various dyes. Among the inks, black inks are important since they are used in mono-color and full-color images. As dyes for black inks, many dyes have been proposed as described in prior patent applications, for example, JP-55144067A(1980), JP-57207660A(1982), JP-58147470(1983), JP-59093766A(1984), JP-62190269A(1987), JP-62246975A(1987), JP-63022867A(1988), JP-63033484A(1988), JP-01093389A(1989), JP-02140270A(1990), JP-03167270A(1991), JP-03200852A(1991), JP-04359065A(1992), JP-06172668A(1994), JP-06248212A(1994), JP-07026160A(1995), JP-07268256A(1995) and the like. However, the prior dyes cannot satisfy the commercial requirements as described above.

     The compound represented by the general formula (1) can be synthesized, for example, according to the following method. That is, the compound of the general formula (1) can be synthesized by: 
     diazotizing a compound of the general formula (6):                           
     wherein Y is hydrogen, halogen or (C1-C4) alkyl and A is as defined above, in an aqueous medium; 
     coupling with a compound of the general formula (7):                           
     wherein m is 0 or 1; 
     hydrolyzing the resultant disazo compound of the general formula (8):                           
     wherein A, Y and m are as defined above, to a compound of the general formula (9):                           
     wherein A and m are as defined above; 
     diazotizing the compound of the general formula (9); and 
     coupling with a compound of the general formula (4′):                           
     wherein R 5 , R 6  and R 7  are as defined above. Alternatively, the compound of the general formula (8) may be diazotized again, coupled with the compound of the general formula (4′) and then hydrolyzed to obtain the compound of the general formula (1). 
     Each of the compounds of the general formulae (6), (7) and (4′) can be prepared according to the known method per se. 
     Diazotization of the compound of the general formula (6) is effected according to the known method per se, for example, using nitrites such as an alkali metal nitrite (e.g. sodium nitrite) at −5 to 30° C., preferably 0 to 10° C. in an aqueous inorganic acid medium. 
     Coupling of the diazo compound of the general formula (6) with the compound of the general formula (7) is effected under the known condition per se. It is conveniently effected in an aqueous or aqueous organic medium at −5 to 30° C., preferably 0 to 10° C. under the weak acidic or alkaline pH. Preferably, it is effected under the neutral or alkaline pH, e.g. 7 to 11. The pH is adjusted by the addition of any base. The base to be used includes alkali metal hydroxides such as lithium hydroxide and sodium hydroxide; alkali metal carbonates such as lithium carbonate, sodium carbonate and potassium carbonate; alkali metal acetates such as sodium acetate; ammonia; or organic amines. The compounds of the general formulae (6) and (7) are used in approximately stoichiometric amounts in this reaction. 
     The preparation of the compound of the general formula (9) by hydrolyzing the compound of the general formula (8) is effected according to the known method per se. The heating in an aqueous alkaline medium is convenient. For example, it is effected by adding sodium or potassium hydroxide to a reaction solution containing the compound of the general formula (8) until the pH is 11 or more and then heating to the temperature of 20 to 150° C., preferably 30 to 100° C. Preferably, the pH of the reaction solution is kept to be 10 to 12. 
     Diazotization of the compound of the general formula (9) resulting from hydrolyzing is effected under the same condition as that described in the diazotization of the compound of the general formula (6). 
     Coupling of the diazotized product of the compound of the general formula (9) with the compound of the general formula (4′) is effected under the known condition per se. It is effected in an aqueous or aqueous organic medium at the temperature of 0 to 30° C., preferably 10 to 20° C. and the pH of 4 to 10, preferably 6 to 8. 
     After the coupling reaction, the compound represented by the general formula (1) of the present invention can be isolated in the form of free acid by adding any mineral acid. The thus-isolated free acid may be washed with water or an acidified water to remove inorganic salts. The acid type dye having a low salt content can be converted to a solution containing its corresponding salt by neutralizing with hydroxide and/or carbonate (e.g. LiOH, Li 2 CO 3 , NaOH, Na 2 CO 3  or K 2 CO 3 ) or amine in an aqueous medium. Preferable examples of the amine include ammonia, ethanolamine, diethanolamine, triethanolamine, N-methyl-N-ethanolamine, N-methyl-N,N-diethanolamine, 2-(2-hydroxyethoxy)-ethylamine, di-2-(2-hydroxyethoxy)-ethylamine, tri-2-(2-hydroxyethoxy)-ethylamine or the like.
