摘要： Dichroic azo-azomethine dyes of formula (A) or (B), wherein Ar1 to Ar10 are specific (hetero)aromatic moieties and L is a linking group, as defined in the present claims, a dichroic dye mixture comprising said azo-azomethine dyes and a process for preparing the dyes are provided. The dyes are well suited for combination with liquid crystal material for use, inter alia, in a light absorption anisotropic element, for example, in a switchable optical device or an optically anisotropic film.

摘要： An azo compound and an ink composition containing the azo compound are used as inks for ink jet recording and have excellent gas (ozone) resistance when recording is done on special ink jet paper. The azo compound is represented by formula (1) or a tautomer thereof, or a salt of these. In formula (1), R1 represents a C1-C4 alkyl group, R2 represents a cyano group, R3 and R4 each independently represent a C1-C4 alkoxy, R5-R10 each independently represent a group represented by formula (2), and R11-R13 each independently represent a nitro group. In formula (2), R14 is an anilino group, and R15 is a mono- or di-C1-C6 alkylamino group

摘要： Compounds which in the form of the free acid correspond to the formula

WHEREIN R1, R2, n1, n2 and n3 have the meaning given in the description. The new dyestuffs dye vegetable and animal fibre materials and are particularly well suited for dyeing and printing of leather. They show good fastness properties, such as e.g., resistance to acid, resistance to alkalies, resistance to formaldehyde, resistance to solvents, resistance to fatliquoring, or dyeability in hard water; in particular the good fastness to light of the dyestuffs is to be stressed.
摘要翻译：游离酸形式的化合物对应于式WHEREIN R1，R2，n1，n2和n3具有说明书中给出的含义。新型染料染料植物和动物纤维材料，特别适用于皮革的染色和印花。它们具有良好的牢度性能，例如耐酸性，耐碱性，耐甲醛，耐溶剂性，耐油性，或在硬水中的可染性; 特别是染色剂的耐光牢度是要强调的。
