    • Metal complex dyes comprising a metalizable azo compound represented by one of Formulas [I] through [IV]: ##STR1## In Formulas [I] through [IV], Ps represents a phosphono group in the form of a free acid or a salt; Sf represents a sulfo group in the form of a free acid or a salt; m is 0, 1 or 2. R.sup.1 represents a hydrogen atom or an amino group; X represents a hydroxyl group, an alkoxy group having a carbon number of 1 or 2 or a carboxyl group. Y represents a hydroxyl group, an alkoxy group having a carbon number of 1 or 2, a carboxyl group or a methyl group; R.sup.2 represents a hydrogen atom or a hydroxyl group; A represents a phenyl group or naphthyl group selected from the group comprising the following 1 through 4: ##STR2## In the above formulas 1 through 4, Sf has the same definition as above; n is 0, 1 or 2. R.sup.3 represents a hydroxyl group or a carboxyl group; R.sup.4 represents a hydroxyl group, a carboxyl group or an amino group; R.sup.5 and R.sup.6 independently represent a hydroxyl group or a carboxyl group; R.sup.7 and R.sup.8 independently represent a hydrogen atom, a hydroxyl group or an amino group. B has the same definition as A above except that R.sup.3 represents a hydroxyl group, a carboxyl group or an amino group. R.sup.9 represents a hydrogen atom, a methyl group, an alkoxy group having a carbon number of 1 or 2 or a sulfo group in the form of a free acid or a salt; D represents a coupling component residue having a metalizable hydroxyl group at the position adjoining to the azo group.Use of these metal complex dyes makes it possible to dye metal-tanned leather with good permeability and excellent color fastness to rubbing and color fastness to light.
    • 包含由式[I]至[IV]之一表示的可金属化的偶氮化合物的金属络合物染料:式(I)中的化合物: [I]〜[IV]中,Ps表示游离酸或盐形式的膦酰基; Sf表示游离酸或盐形式的磺基; m为0,1或2.R 1表示氢原子或氨基; X表示羟基,碳数为1或2的烷氧基或羧基。 Y表示羟基,碳数为1或2的烷氧基,羧基或甲基; R2表示氢原子或羟基; A表示选自包括以下+ E,crc / 1 /至+ E,crc / 4 /:图像+ E,CRC / 1 /图像+ E,CRC / 2的苯基或萘基 在上述公式+ E中,crc / 1 /至+ E,crc / 4 /,Sf具有与上述相同的定义; n为0,1或2.R 3表示羟基或羧基; R4代表羟基,羧基或氨基; R5和R6独立地表示羟基或羧基; R 7和R 8独立地表示氢原子,羟基或氨基。 B具有与上述相同的定义,只是R3表示羟基,羧基或氨基。 R9表示氢原子,甲基,碳数为1或2的烷氧基或游离酸或盐形式的磺基; D表示在与偶氮基相邻的位置具有可金属化羟基的偶合成分残基。 使用这些金属络合染料使得可以染色具有良好透光性和优异的耐色牢度的金属鞣革,并且具有良好的耐光色牢度。
