Zusammenfassung:A water-soluble dye, free from cellulose reactive groups, of the formula: wherein each of Ar and Ar , independently, represents an optionally substituted phenyl or naphthyl radical, each of R and R , independently, represents -OR or -NR R , R represents hydrogen or alkyl, R represents hydrogen, alkyl, aryl or a radical of the formula -(CaH2aO)m(CbH2bO)nH, R represents hydrogen, alkyl, aryl, a radical of the formula -(CaH2aO)m(CbH2bO)nH or a radical of a mono- or disazo dye, or R and R together form a morpholine ring, a and b are different integers from 1 to 8, m is an integer from 1 to 10, n is an integer from 0 to 9, each of R and R , independently, represents hydrogen or alkyl, M represents hydrogen, ammonium or a monovalent metal, and each of p and q, independently is an integer from 1 to 3. The dyes are suitable for use in ink jet printing.
