Abstract
Description
Vynález se týká modrého 1 : 2 chromokomplexního azobarviva pro barvení vlny a polyamidu.The invention relates to a blue 1: 2 chromocomplex azo dye for dyeing wool and polyamide.
; 2 kovokomplexní azobarviva jsou význačnou skupinou barviv vybarvující vlnu a polyamid ze slabé 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 weak 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 silné závislé na vhodném umístění eulfoskupiny 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 dyeing properties. The properties of the dyes are then strongly dependent on the appropriate positioning of the sulfo group and the charge distribution in the dye molecule.
Nyní bylo nalezeno, že nevýhody spojené se zavedením sulfoskupiny do molekuly barviva odstraňuje nové modré 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 blue 1: 2 chromocomplex azo dye of the invention of the formula
kde M w Na, К nebo NH^.where M w Na, К 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 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:
49#3 g (0,1 mol) 1 : 1 chromitého komplexu monoazobarviva 5-nitro-2-aminofenol-4*>49 # 3 g (0.1 mol) 1: 1 chromium complex of 5-nitro-2-aminophenol-4 monoazo dye *>
—1-naftol-4-sulfokyselina ve formě filtračního koláče se vnese do 1 000 ml sodově alkalické suspense obsahující 36,6 g (0,1 mol) monoazobarviva 5-nitro-2-aminofenol-$>- 1-Naphthol-4-sulfoacid in the form of a filter cake is added to 1000 ml of a sodium alkaline suspension containing 36.6 g (0.1 mol) of the monoazo dye 5-nitro-2-aminophenol
-o l-acetamino-7-naftol. Po 2 hodinách zahřívání na 90 °C vznikne roztek nesymetrického 1 : 2 chromitého komplexu. Odpařením se získá 100 g silného barviva s velmi dobrou rozpustností za studená, které vybarvuje vlnu a polyamid v neutrálním až slabě kyselém prostředí modrým odstínem.1-acetamino-7-naphthol. After heating at 90 ° C for 2 hours, a non-symmetrical 1: 2 chromium complex is formed. Evaporation gave 100 g of a strong dye with very good cold solubility, which dyed wool and polyamide in a neutral to slightly acidic environment with a blue tint.
