[Also in Division D1] A stable dispersion of an optical brightener containing a carboxylic acid and/or sulphonic acid group in a liquid dispersing medium consisting of an anhydrous water miscible di- or trihydric alcohol and/or an ether of the alcohol and/or a water-soluble polyether of the alcohol may contain 10% to 90% optical brightener. The optical brightener may be a water soluble derivative of bis-triazinylaminostilbene disulphonic acid or a water soluble 1,3 diaryl pyrazoline; examples are given. The dispersions may be prepared by treating the optical brightener with the dispersing medium and optionally with a non-ionic dispersing agent, for example polyethoxylated nonyl phenol, in a kneading or milling device until the particles have sizes 0.5 to 3 micrometres.

    • The invention comprises reactive dyestuffs of the general formula wherein D is an organic dye residue, Y is a covalent bond or a divalent bridging group, R is H or C1-C4 alkyl, R1 is H or CH2OR and n is 1 or 2. Preferably D is a residue of an anthraquinone, phthalocyanine, azo (mono and dis azo) or an anthrone dye and nitro and triphenylmethane dyes are also described. The divalent bridging groups specified are -SO2-, -alk-SO2-, -alk-O-, -S-alkylene, -CO-, -alk-CO-, or alkylene wherein alk and alkylene have 1 or 2 carbon atoms. They are prepared by alkoxymethylating or methylolating the corresponding N-unsubstituted diamide, methylolation being carried out using formaldehyde at 20 DEG to 90 DEG C. and at pH values above 7. Example 16 describes purification of an unsubstituted diamide starting material, Example 28 etherification using methanol of the N-methylol groups and Example 30 reaction of a monoazo dye with a triazine compound containing the bis-N-methylolated diamide group. The dyes may be applied to reactive-hydrogen containing substrates, e.g. cellulosic textiles in aqueous acidic medium eliminating a group HOR to form a covalent link. Reference has been directed by the Comptroller to the Specification 842,802.ALSO:In Example 1 m-nitrobenzene sulphonyl chloride is condensed with di-2-cyanoethylamine, the product hydrolysed to convert the cyano groups to amide groups and the nitro group finally reduced to a primary amino group. In Example 15 m-nitrobenzoyl chloride is reacted as above. In Example 16 N-ethyl-N-(2-aminoethyl) m-toluidine is reacted with acrylonitrile and the addition product hydrolysed to the di-amide. Examples 17 and 18 describe hydrolysis of N,N-di-(2-cyanoethyl) aniline and the 4-nitro derivative to the corresponding diamides and the nitro compound is subsequently reduced to the amino derivative which forms a hydrochloride. Reference has been directed by the Comptroller to the Specification 842,802.

    • The invention comprises the compound and its salts. The compound is prepared by reacting cyanuric chloride in any desired order of succession in the molecular ratio of 2:1:2:2 with 4,41-diaminostilbene-2:21-disulphonic acid, 1-aminobenzene-4-sulphonic acid and diethylamine. Preferably, cyanuric chloride is condensed in the molecular ratio of 2:1 with 4,41-diaminostilbene-2,21-sulphonic acid to give the compound which is then treated to exchange one chlorine atom in each dichlorotriazinyl residue for the residue of p-aminobenzenesulphonic acid to give the compound the two remaining chlorine atoms each being subsequently exchanged for a diethylamino group. An example describes the preparation of the sodium salt, other specified salts being the potassium, lithium, ammonium, amine, barium and calcium salts. The compound is an optical brightening agent (see Divisions B5, C4, C5, D1). Reference has been directed by the Comptroller to Specification 705,406.ALSO:The compound and its salts may be used as optical brightening agents in admixture with dyestuffs or pigments, as additives to dyebaths, printing, resist or reserve pastes, or i combination with detergents such as soaps, salts of sulphonate detergents such as sulphonated 2-(higher alkyl)-benzimidazoles and salts of monocarboxylic acid esters of 4-sulphophthalic acid with higher fatty alcohols, salts of fatty alcohol sulphonates, alkylarylsulphonic acids, condensation products of higher fatty acids with aliphatic hydroxysulphonic or aminosulphonic acids, and non-ionic detergents such as polyglycol ethers derived from ethylene oxide and C8-22 fatty alcohols, alkylphenols or fatty amines. Reference has been directed by the Comptroller to Specification 705,406.ALSO:The compound and its salts are used in admixture with chemical bleaches, as additives to bleaching baths, or for optically brightening fibrous materials. The fibrous materials may be in the form of fibres, filaments, yarns, woven or knitted fabrics, or felt. Specified materials are cotton, hemp, flax, linen, jute, ramie, rayon, viscoses, cellulose butyrate, acetylcellulose, polyesters, polyamides, feathers, hairs, pelts and hides and leather made therefrom, straw, wool, wood pulp, paper and cardboard. Examples describe the brightening of paper, bleached cotton fabric and bleached polyamide fabrics of filament or staple fibres. Reference has been directed by the Comptroller to Specification 705,406.
