Description
Vynález ae týká žlutého 1 : 2 chromokomplexního azobarviva pro barvení vlny a polyamidu.The invention relates to a yellow 1: 2 chromocomplex azo dye for dyeing wool and polyamide.
: 2 kovokomplexní azobarviva jsou význačnou skupinou barviv vybarvující vlnu a polyamid ze slabě kyselého až neutrálního prostředí vybarveními s vysokými suchými i mokrými stálostmi*: 2 metal-complex azo dyes are a prominent group of dyes that dye wool and polyamide from weakly acid to neutral dyes with high dry and wet fastnesses *
Vysoké rozpustnosti těchto barviv je v poslední době dosahováno přítomností jedné i více sulfoskupin v molekule, což ale může v některých případech nepříznivě ovlivnit barvířské vlastnosti* Vlastnosti barviv jsou potom silně závislé na vhodném umístění sulfoskupiny a rozložení náboje v molekule barviva.The high solubility of these dyes has recently been achieved by the presence of one or more sulfo groups in the molecule, which may in some cases adversely affect the dyeing properties. The dye properties are then strongly dependent on the appropriate sulfo group placement and charge distribution in the dye molecule.
Nyní bylo nalezeno, že nevýhody spojené se zavedením sulfoskupiny do molekuly barviva odstraňuje nové žluté 1 : 2 chromokomplexní azobarvivo podle vynálezu vzorceIt has now been found that the disadvantages associated with the introduction of a sulfo group into a dye molecule are overcome by the new yellow 1: 2 chromocomplex azo dye of the invention of the formula

kde M Na, К nebo NH^.where M Na, K or NH 2.
Výhody barviva podle vynálezu spočívají v jeho výborné vytažlivosti, egalitě, vysokých stálostech vybarvení a zejména v jeho vysoké rozpustnosti za studená, což umožňuje využití moderních barvicích postupů (například kontinuální barvení) uplatňovaných v posledních letech*The advantages of the dye according to the invention lie in its excellent extensibility, leveling, high color fastness and in particular its high cold solubility, which makes it possible to use modern dyeing processes (for example continuous dyeing) applied in recent years *
Příklad:Example:
57,4 g (0,1 mol) chromitého 1 : 1 komplexu monoazobarviva antranilová kyselina --^1(2 ,5 -dichlor-4 -sulfofenyl)-3-methyl-5-pyrazolon ve formě vlhkého krystalického koláče se vnese do I 000 ml 20 °C teplé kopulační euspense obsahující 32,2 g (0,1 mol) monoazobarviva antranilová kyselina —»> l-fenyl-3-methyl-5-pyrazolon. Po rozmíchání se suspense vyhřeje na 85 °C a současně přídavky roztoku sody udržuje pH na hodnotě 6,0 až 7,0* Po 1 až 2 hodinách zahřívání vznikne roztok nesymetrického 1 : 2 chromitého komplexu. Odpařením se získá 125 g silného, vysoce rozpustného barviva, které barví z neutrálního až slabě kyselého prostředí vlnu a polyamid jasným žlutým odstínem.57.4 g (0.1 mol) of chromium (III) chromium 1: 1 monoazoic dye complex anthranilic acid - 1 1 (2,5-dichloro-4-sulfophenyl) -3-methyl-5-pyrazolone as a wet crystalline cake is introduced into 000 ml of 20 ° C warm coupling suspension containing 32.2 g (0.1 mol) of anthranilic acid monoazo dye → 1-phenyl-3-methyl-5-pyrazolone. After stirring, the suspension is heated to 85 ° C while maintaining the pH of 6.0 to 7.0 by the addition of the soda solution. After 1 to 2 hours of heating, an unsymmetrical 1: 2 chromium complex solution is formed. Evaporation gave 125 g of a strong, highly soluble dye which stains wool from neutral to slightly acidic medium and the polyamide with a bright yellow hue.
