Description
Monosulfonovaná 1:2 chromkomplexní barviva (I) se obvykle připravují koordinační ohromací nesulfonovaného o,o1-dihydroxyazobarviva a 1:1 chromkomplexu o,o'-dihydroxyazobarviva obsahujícího v molekule ' jednu sulfoskupinu. Při této reakci vznikají kromě žádaného asymetrického 1:2 chromkomplexního barviva v malé míře i dvě symetrická 1:2 chromkomplexní barviva, a to jednak bez sulfoskupiny, jednak se dvěma sulfoskupinami (II) v molekule.Monosulfonated 1: 2 chromkomplexní dyes (I) are usually prepared by coordinating ohromací unsulphonated, -dihydroxyazobarviva 1 and 1: 1 chromkomplexu o, o'-dihydroxyazobarviva containing in the molecule 'one sulfo group. In this reaction, in addition to the desired asymmetric 1: 2 chromium complex dye, two symmetrical 1: 2 chromium complex dyes are formed to a small extent, both without a sulfo group and with two sulfo groups (II) per molecule.
Nyní. byla nalezena šedá až černá 1:2 chromkomplexní azobarviva sestávajíoí podle vynálezu ze směsi monosulfonovaného (I) a disulfonovaného (II) 1:2 chromkomplexuNow. gray to black 1: 2 chromium complex dyes have been found consisting of a monosulfonated (I) and disulfonated (II) 1: 2 chromium complex according to the invention

Υχ = N02, SO2NH2, SO2NHCH3, Cl, je Y2 = H aΧ χ = NO 2 , SO 2 NH 2 , SO 2 NHCH 3 , Cl, is Y 2 = H and
Y2 = N02, je Υχ = H neboY 2 = NO 2 , is Υ χ = H or
kde Z = H, N02 kde Z3 = N02 a Z2 = SO3H nebo Z^ = SOjH a Z2 = N02 v poměru I:II = 0,05 až 0,95:0,95 až 0,05 a připravitelná koordinační chromací směsi nesulfonovaného a sulfonovaného o,o'-dihydroxyazobarviva a 1:1 chromkomplexu o,o1-dihydroxyazobarviva obsahujícího v molekule jednu sulfoskupinu nebo přímo míšením I a II za mokra resp. za sucha.where Z = H, NO 2 where Z 3 = NO 2 and Z 2 = SO 3 H or Z 2 = SO 3 H and Z 2 = NO 2 in the ratio I: II = 0.05 to 0.95: 0.95 to 0 , 05 and coordinating chromací obtainable mixtures of sulfonated and non-sulfonated o, o'-dihydroxyazobarviva and 1: 1 chromkomplexu of about 1 -dihydroxyazobarviva containing one sulfo group in the molecule or directly by mixing I and II, or wet. dry.
Zvýšením obsahu disulfonovaného 1:2 chromkomplexu (II) lze příznivě ovlivnit barvířské vlastnosti monosulfonovaného 1:2 chromkomplexu: barviva s vyšším podílem disulfonované složky (II) vykazují výrazné zlepšení rozpustnosti za studená při zachování dalších barvířských vlastností jako je například vytažlivost a egalita; vlnu a PAD vybarvuji ze slabě kyselé až neutrální lázně, lze je dobře kombinovat s jinými barvivý stejného nebo i jiného kovokomplexního sortimentu, případně s běžnými kyselými barvivý.By increasing the content of disulfonated 1: 2 chromium complex (II), the dyeing properties of the monosulfonated 1: 2 chromium complex can be favorably influenced: dyes with a higher proportion of disulfonated component (II) show a marked improvement in cold solubility while maintaining other dyeing properties such as ductility and leveling; wool and PAD color from weakly acid to neutral bath, can be well combined with other dyes of the same or other metal-complex assortment, or with conventional acid dyes.

Po několika hodinách zahřívání na 80 až 90 °C vznikne roztok směsného 1:2 chromitého komplexu. Odpařením se získá 120 g silného barviva, které barví vlnu a PAD šedým až černým odstínem.54.2 g (0.1 mol) of chromium (III) 1: 1 monoazobraviva 6-nitro-1-diazo-2-naphthol-4-sulfoacid-J complex. 2-Naphthol in the form of a paste is introduced into a 70 ° C warm alkaline suspension of 15.5 g (0.05 mol) monoazo dye 4-nitro-2-aminophenol → 2-naphthol and 22 g (0.05 mol) monoazo dye 6- nitro-1-diazo-2-naphthol-4-sulfoacid-2-naphthol. After a few hours of heating to 80-90 ° C, a mixed 1: 2 chromium complex solution was formed. Evaporation gave 120 g of a strong dye which dyed wool and PAD with a gray to black shade.
