Description
(54) BASIC DYESTUFF LIQUID FORMULATIONS
(71) We, IMPERIAL CHEMICAL INDUSTRIES LIMITED, Imperial Chemical
House, Millbank, London SW1P 3JF, a British Company, do hereby declare the invention, for which we pray that a patent may be granted to us, and the method by which it is to be performed, to be particularly described in and by the following statement:
This invention relates to concentrated stable liquid formulations of certain basic dyestuffs in mixtures comprising liquid polyhydric alcohols, aliphatic carboxylic acid and water.
Concentrated solutions of basic dyes are known and are more convenient for use in the dyeing industry than powder brands as the latter have to be dissolved in the dyeing liquor whereas concentrated solutions mix into the liquid relatively instantaneously.
Concentrated solutions in polyhydric alcohols of salts of basic dyes with carboxylic acids are known from British Patent No. 981547. Such solutions may contain water and may contain a water soluble carboxylic acid, preferably in not than one stoichiometric excess, this amount preventing hydrolysis of the carboxylic salt.
Despite the fact that such dyestuff carboxylic acid salts are said to be much more soluble than the other salts for example the quaternary chlorides or hydrochlorides, we have found that concentrated solutions of certain basic dyestuffs in the form of salts other than the carboxylates can be obtained in mixtures of certain carboxylic acids, polyhydric alcohols and water. There is thus no need to convert the dyestuffs generally manufactured as other salts into carboxylic acid salts before preparing concentrated solutions thereof.
Thus according to the present invention there are provided concentrated solutions of basic dye salts comprising
(a) from 5% to 80% by weight of a basic dyestuff salt as hereinafter defined,
(b) from 10% to 50% by weight of water
(c) from 10% to 50% by weight of an optionally substituted carboxylic acid having 1 to 4 carbon atoms and
(d) from 6% to 30% by weight of a liquid polyhydric alcohol.
By the term a basic dyestuff salt we mean a basic or cationic dyestuff of the nitroso, nitro, quinoneimine, azine, thiazine, pyrazolone, xanthene, acridine, quinoline, phthalocyanine and especially the azo benzene, pyridone, naphtholactam, anthraquinone, hemicyanine, azacarbocyanine and diazacarbocyanine classes, said cationic dyestuff having an anion other than a carboxylate anion.
Preferably the solution contains from 15% to 40% by weight of the dyestuff salt.
Examples of anions which may be present in the dyestuff salt include inorganic anions such as chloride, bromide, nitrate, bisulphate, sulphate and tetrachlorozincate and organic anions such as methosulphate, ethosulphate, p-tolylsulphonate.
Preferred anions are chloride, bisulphate and methosulphate.
Examples of optionally substituted carboxylic acids having 1 to 4 carbon atoms include formic acid, acetic acid, propionic acid, butyric acid, glycollic acid, chloroacetic acid, lactic acid and tartaric acid, of these, acetic acid is preferred.
It is preferred that approximately equal amounts of water and the optionally substituted carboxylic acid of 1 to 4 carbon atoms be used.
Examples of liquid polyhydric alcohols which can be used include ethylene glycol, diethylene glycol, triethylene glycol, 1,2-propylene glycol and glycerol.
The concentrated solutions of the invention are particularly valuable where the dyestuff salt is as hereinbefore defined and has a cationic group which contains a quaternary nitrogen atom.
The concentrated solutions may be made by dissolving the basic dyestuff salt in the mixture of solvents. In order to aid dissolution the mixtures may be warmed to say 40 to 50"C if necessary. Alternatively the basic dyestuff salt may be dissolved in one of the solvents and that mixture then mixed with further solvent to give the final concentrated solution.
The concentrated solutions of the present invention are of good stability to storage at low temperatures and are readily incorporated into a dyeing liquor, for example a dyeing liquor used for dyeing polymers or copolymers of acrylonitrile or blends containing such polymers or copolymers.
The invention is illustrated by the following examples in which all parts and percentages are by weight except where otherwise stated.
Example 1
30 Parts of the dyestuff of formula:
are dissolved in a mixture of 10 parts of water, 30 parts of acetic acid and 30 parts of ethylene glycol by stirring at ambient temperature. The solution thus formed shows no precipitation after storage for at least one month at 0 C.
Example 2
20 Parts of the dyestuff of formula:
are dissolved in 26.8 parts of water, 23.6 parts of acetic acid, 23.6 parts of propionic acid and 6 parts of ethylene glycol by stirring at ambient temperature. The solution thus obtained is stable at 0 C.
Example 3
30 Parts of the dyestuff of formula:
are dissolved in 40 parts of water, 20 parts of acetic acid and 10 parts of ethylene glycol by stirring at ambient temperature. The solution thus formed shows no precipitation after storage for at least one month at OOC.
WHAT WE CLAIM IS:
1. Concentrated solutions of basic dye salts comprising only
a) from 5% to 80% by weight of a basic dyestuff salt as hereinbefore defined
b) from 10% to 50% by weight of water
c) from 10% to 50% by weight of an optionally substituted carboxylic acid having 1 to 4 carbon atoms and
(d) from 6% to 30% by weight of a liquid polyhydric alcohol.
2. Concentrated solutions of basic dye salts as claimed in Claim 1 containing from 15% to 40% by weight of the basic dyestuff salt.
