wherein Q¹ represents a phenyl or naphthyl group, Q represents a phenyl group which is substituted by at least one substituent selected from hydroxy and substituted or unsubstituted amino, and which may be further substituted, and R¹, R, R³ and R⁴ each independently represent hydrogen, hydroxy, lower alkyl, lower alkoxy or substituted or unsubstituted amino, or a salt thereof; and a polarizing film which comprises the tetrakisazo compound or a salt thereof and which may further comprise other organic dyes.
摘要:
A reactive dye composition comprising an anthraquinone compound of formula:
wherein Z represents -CH=CH 2 or -CH 2 CH 2 Z 1 in which Z 1 represents a group removable by the action of an alkali other than a carboxypyridinio group and an anthraquinone compound of formula (II):
and a method for dyeing or printing cellulose-containing fiber materials using the same.
摘要:
A dye-containing polarizing film having neutral color which comprises at least one disazo dye represented by the formula (I) in the form of the free acid
wherein Me is a transition metal selected from copper, nickel, zinc and iron, A 1 is phenyl or naphthyl which may be substituted or substituted. B 1 is 1-naphthol or 2-naphthol residue which may be unsubstituted or substituted and in which its hydroxy group is adjacent to the azo group and is linked with the transition metal Me to form the complex, and R 1 is a lower alkoxy; and at least two of other specific dyes, and the film causes no light to break through the film at dark state within the visible radiation wavelength region and is excellent in the polarizing activities as well as the durability to water and heat.
