摘要:
A polarizing film which comprises, in a film substrate, at least one dye selected from:
1) a dye of formula (1):
Q¹-N=N-Q²-X-Q³-N=N-Q⁴ (1)
wherein: Q¹ and Q⁴, which are the same or different, are each unsubstituted or substituted phenyl or naphthyl; Q² and Q³, which are the same or different, are each unsubstituted or substituted phenylene; and X is -N=N- or provided that, when X is -N=N- and both of Q² and Q³ are unsubstituted phenylene, at least one of Q¹ and Q⁴ is not phenyl which is substituted only by an alkyl-substituted amino or is not phenyl substituted by an alkyl-substituted amino and by methyl; and 2) a dye of formula (2): wherein: each Me, which are the same or different, is a transition metal selected from copper, nickel, zinc and iron; Q⁵ and Q⁶, which are the same or different, are each an unsubstituted or substituted 1,2-naphthalene group; Y is -N=N- or and R¹ and R², which are the same or different, are each hydrogen, lower alkyl, lower alkoxy or sulfo.
摘要:
A trisazo compound represented by the following formula (I) in the free acid form:
wherein Q is an phenyl or naphthyl group both of which may be unsubstituted or substituted; one of the A and B is hydroxy group and the other is amino group; K is 1 or 2; and one of m and n is 1 and the other is 0; a method for dyeing fiber materials, paper or leather by using the trisazo compounds and an ink containing the trisazo compounds, and the trisazo compound is excellent in solubility, and good in storage stability and free from clogging of nozzle caused by deposition. The ink using the trisazo compound gives a deep black-colored image excellent in clarity, water-durability and durability to light.
摘要:
An asymmetric dioxazine compound of the following formula:
wherein R is sulfo, halogeno, alkoxy, alkyl or carboxy; R₁ and R₂ are each hydrogen or alkyl; R₃ is hydrogen, alkyl or acyl; X₁ and X₂ are each hydrogen, halogeno, alkyl, alkoxy or phenoxy; Y is aliphatic amino having a vinylsulfonyl or β-substituted ethylsulfonyl fiber-reactive group; and Q is unsubstitued, substituted or cyclic amino; is useful for dyeing or printing fiber materials blue with excellence in build-up properties and various fastness properties.
摘要:
A monoazo compound of the formula, wherein D is a heterocyclic or carbocyclic compound residue such as benzothiazolyl and phenyl, X is hydrogen, alkyl, alkoxy, halogeno, acylamino or the like, Y is hydrogen, halogeno, alkyl, alkoxy and the like, R 1 is alkyl, R 2 is C 2 -C 4 alkylene, B is a bridging group such as alkylene and the like, and W 1 , W 2 , W 3 , Z 1 , Z 2 and Z a are independently hydrogen, alkyl, halogeno or the like, which is useful for dyeing hydrophobic fiber materials to give dyed or printed product of a deep color excellent in fastness properties, particularly those such as washing fastness, even after various finishing treatments of the product.
摘要:
A dioxazine compound represented by the following formula (I), wherein V is a direct linkage or in which R 3 is hydrogen or unsubstituted or substituted alkyl, and X is a direct linkage or an aliphatic, araliphatic or aromatic bridging group, provided that X stands for the bridging group as defined hereinabove when V is Y is unsubstituted or substituted phenylene, or unsubstituted or substituted naphthylene, Z is -SO 2 CH=CH 2 or -SO 2 CH 2 CH 2 Z 1 in which Z 1 is a group capable of being split by the action of an alkali, Q is sulfo, hydroxy, halo, alkoxy, unsubstituted or substituted phenoxy or unsubstituted or substituted amino, and R 1 and R 2 independently of one another are each hydrogen or unsubstituted or substituted alkyl, which is useful for dyeing or printing fiber materials to give a dyed or printed product of a blue color superior in fastness properties, particularly those such as chlorine fastness, with superior build-up property.
摘要:
A heterocyclic compound of the formula, wherein A and B are each hydrogen, alkyl or alkoxy, Y is hydrogen, alkyl, alkoxy or -O-R²-X-R¹ or Y and B are taken together with each other to form methylenedioxy, R¹ is alkyl, phenyl or alkenyl, R² is unsubstituted or substituted alkylene, and X is -O-, -S-, -SO-, -SO₂- or in which R³ is hydrogen or alkyl, with the proviso that R¹ is C₃ or C₄ alkyl or alkenyl, or C₁ - C₄ alkyl when R² is unsubstituted ethylene or propylene, respectively, X is -O- or -S-, and Y and B don't form methylenedioxy, which is useful for dyeing or printing hydrophobic fiber materials with superior dyeability to give a dyed or printed product of a red color excellent in fastness properties, particularly those such as washing fastness.
