摘要： NEW MATERIAL:A compound shown by formula I (M is H or alkali metal; R and R are acylamino; R is alkoxy; R is alkyl or alkoxy; X and Y are halogen, aromatic amino residue; aliphatic amino residue or OH which may be etherified). EXAMPLE:Compound shown by formula II. USE:A dyestuff which dyes cellulose fibers and nitrogen-containing fibers in brown with improved thermotropy resistance. Cellulose fibers and polyester fibers can be simultaneously dyed by one bath by one stage method by adding the dyestuff and disperse dye to a dyeing bath. PREPARATION:For example, a compound shown by formula III-V is diazotized and coupled twice to give a disazo derivative shown by formula VI. Then the compound is condensed with a compound shown by formula VII and a compound shown by formula Y-H in any order in an aqueous medium.

摘要： NEW MATERIAL:Compounds of formula I [wherein R1 is a lower alkyl, a lower alkoxy; R2 is H, R1, NHCOR3; R3 is amino, methyl, ethyl, phenyl, succinyl, maleinyl; R is a (substd.) lower alkyl; Z is vinyl, CH2CH2L; L is a group which can be eliminated by the action of an alkali; A is (substd.) phenylene, naphthylene; X is Cl, F, an aliph. or arom. amino residue, methoxy, phenoxy]. EXAMPLE:Compd. of formula II. USE:Bisazo dyes which dye materials having hydroxyl or amide groups navy blue. PREPARATION:Compds. of formula III-VI (wherein hal is Cl, F) are used. When the compd. where X is Cl, F is to be prepd., the compds. of formulas III-V are condensed in an aq. medium. When the compd. where X is an aliph. or arom. amino residue, methoxy, phenoxy, is to be prepd., the compds. of formulas III-VI are condensed in an aq. medium. The resulting compd. of formula VII is coupled with a diazonium compd. obtd. by diazotizing a compd. of formula VIII.

摘要： NEW MATERIAL:The compound of formula I [M is H or alkali metal; R and R are H or alkyl; Y is halogen or group of formula II (R is H or alkyl; R and R are H, alkyl or alkoxy); Z is reactive group capable of forming a covalent bond to OH and/or amino group; m and n are 0 or 1]. USE:Dye for dying cellulosic fiber such as cotton, flax, rayon, etc., and nitrogen- containing fiber such as polyamide, wool, silk, etc., in bluish red - orange color. Cellulosic fiber and polyester fiber can be dyed at the same time by a one-bath one-stage dying. PREPARATION:1mol of the diamine of formula III is tetrazotized and coupled with 2mol of the compound of formula IV.

摘要： NEW MATERIAL:A compound of formula I (M is H or alkali metal; Dz is residue of benzene- or naphthalene-based diazo component; R is H or alkyl; R and R are each H, alkyl, alkoxy, halogen or -SO3M; X is aromatic or aliphatic divalent residue). EXAMPLE:A compound of formula II. USE:Dyes for dyeing in a range blue-red to red-violet, etc., cellulose fibers such as cotton, rayon or hemp and nitrogen-contg. fibers such as polyamide, wool or silk. Capable of dyeing cellulose fibers under the pH condition in dyeing polyester fibers. PREPARATION:For example, a coloring matter of formula III and a compound of formula H2N-X-NH2 are condensed each other in a molar ratio of 2 to 1, the resultant disazo compound is subjected to condensation with a compound of formula IV in such an amount as to be 2 moles for mole of the compound of the formula H2N-X-NH2.
