    摘要： A dye-containing polarizing film which comprises at least one dye selected from:dye represented by the following formula(1):Q1--N.dbd.N--Q2--X--Q3--N.dbd.N--Q4 (1)wherein Q1 and Q4 are phenyl or naphthyl group, Q2 and Q3 are phenylen group, X is azo or azoxy, and dye represented by the following formula(2): ##STR1## wherein Me is a transition metal selected from copper, nickel, zinc and iron, Q5 and Q6 are 1-naphthol or 2-naphthol residue, Y is azo or azoxy, R1 and R2 are hydrogen, lower alkyl, lower alkoxy or sulfo. The polarizing film exhibits polarizing activities not smaller than those of a iodine containing polarizing film, has excellent durability and does not cause light to break through the film by using several types of the specific dye in combination.

    摘要： Trisazo/azoxy dyestuff mixtures which in the form of free acid correspond to the formula ##STR1## in which R denotes H or optionally substituted alkyl,X and Y denote H, alkyl, alkoxy, halogen, hydroxyl, alkylsulphonyl, optionally mono- or di-alkyl-substituted sulphamyl, carboxyl and carboxyalkoxy andK denotes the radical of a coupling component,are outstandingly suitable for dyeing fibre materials containing hydroxyl groups and fibre materials containing amide groups, such as cotton, natural and synthetic polyamide, paper and leather. They give dyeings having good build-up capacity and good combinability.
