Vynález se týká 1 : 2 chromokomplexního azobarviva odstínu bordo pro barvení vlny a polyamidu.The invention relates to a 1: 2 chromo complex azo dye bordo for dyeing wool and polyamide.
: 2 kovokomplexní azobarviva jsou význačnou skupinou barviv vybarvujících 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 wool dyes and polyamide from weakly acid to neutral media with high dry and wet fastnesses.
Vysoké rozpustnosti těchto barviv je v poslední době dosahováno přítomnosti 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, however, may in some cases adversely affect the dyeing properties. The properties of the dyes are then strongly dependent on the appropriate location of the sulfo group and the charge distribution in the dye molecule.
Nyní bylo nalezeno, že nevýhody spojené se zavedením sulfogkupiny do molekuly barviva odstraňuje nové 1 : 2 chromokomplexní azobarvivo odstínu bordo podle vynálezu vzorceIt has now been found that the disadvantages associated with the introduction of a sulfo group into the dye molecule are overcome by the new 1: 2 chromo complex azo dye bordo according to the invention of the formula
kde M « Na, К nebo NH^.wherein M «Na, K or NH ^.
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 kontinuálního barvení) uplatňovaných v posledních letech.The advantages of the dye according to the invention lie in its excellent extensibility, levelness, high color fastness and, in particular, its high cold solubility, which allows the use of modern dyeing processes (e.g. continuous dyeing) applied in recent years.
Příklad:Example:
47,6 g (0,1 mol) 1 : 1 chromitého komplexu monoazobarviva antranilová kyselina — —> l-naftol-4-sulfokyselina ve formě filtračního koláče se vnese do 1 000 ml alkalické suspense 33,9 g (0,1 mol) monoazobarviva 5-nitro-2-aminofenol —> 1-fenyl-3-methyl-5-pyrazolon. Po 2 hodinách zahřívání na 80 až 90 °C vznikne roztok nesymetrického : 2 chromitého komplexu. Odpařením se získá 100 g silného, výborně za studená rozpustného barviva, které barví z neutrálního až slabě kyselého prostředí vlnu a polyamid odstínem bordo.47.6 g (0.1 mol) of a 1: 1 chromium complex monoazo dye anthranilic acid -> 1-naphthol-4-sulfoacid in the form of a filter cake is added to 1000 ml of alkaline suspension 33.9 g (0.1 mol) 5-nitro-2-aminophenol -> 1-phenyl-3-methyl-5-pyrazolone monoazo dyes. After 2 hours at 80-90 ° C, a solution of asymmetric: 2 chromium complex was formed. Evaporation gave 100 g of a strong, excellent cold-soluble dye, which dyes wool from neutral to slightly acidic medium and polyamide to bordo.
