    Abstract: In an example (12) a linear quinacridone having a mean primary particle size of more than 0.1 micron and a specific surface of less than about 30 square metres per gram is ground with plaster to give a red plaster. Cement may be similarly coloured and a red concrete made.ALSO:In examples a red pigment consisting of a linear quinacridone exhibiting in its X-ray diffraction pattern three strong lines, at a double glancing angle of 6.5 degrees, 13.7 degrees and 26.4 degrees, three medium lines at 13.1 degrees, 13.3 degrees and 23.8 degrees and three weak lines at 17.0 degrees, 20.5 degrees and 25.0 degrees and having a mean primary particle size of more than 0.1 micron and a specific surface of less than about 30 square metres per gram is incorporated into (2) nitrocellulose, dibutyl phthalate, ethyl alcohol and ethyl glycol; (3) linseed oil, xylene and the esterification product of phthalic acid and a mixture of glycerin and pentaerythritol; (4) nitrocellulose, dibutyl phthalate, benzyl butyl phthalate, the product obtained by treating cyclohexanone with sodium hydroxide, butyl acetate, methyl acetate and toluene; (5) coconut oil alkyd resin, xylene and n-butanol; (6) a drying unsaturated polyester resin, and monostyrene and a cyclohexanone peroxide paste and then cobalt naphthenate in white spirit and silicone oil solution are added; (7) polyvinyl chloride, di-isooctyl phthalate and titanium dioxide (rutile); (8) polystyrene, polyethylene or polycaprolactam; (9) a mixture of pale crepe rubber, sulphur, stearic acid, 2-mercaptobenzthiazole, hexamethylene tetramine, zinc oxide, chalk and titanium dioxide (anatase) and vulcanisation is effected; (10) titanium dioxide (rutile), lithopone, talc and a solution of sodium hexametaphosphate and a condensation product from sodium naphthalene-2-sulphonate and formaldehyde, and the paste thus obtained is mixed into a polyvinyl acetate dispersion or into a commercial self-vulcanising rubber latex.ALSO:The invention comprises a modification of linear quinacridone (7 : 14-dioxo-5 :7 : 12 : 14-tetrahydroquinolino -(2 : 3-6) - acridine) which exhibits in the X-ray diffraction pattern three strong lines at a double glancing angle of 6.5 degrees, 13.7 degrees and 26.4 degrees, three medium lines at 13.1 degrees, 13.3 degrees and 38.8 degrees and three weak lines at 17.0 degrees, 20.5 degrees and 25.0 degrees, in a mean primary particle size of more than 0.1 micron and with a specific surface of less than about 30 square metres per gram. The modification is made by contacting 7 : 14-dioxo- 5 : 7 : 12 : 14 - tetrahydroquinolino - (2: 3-6)-acridine in a mean primary particle size of less than 5 microns length with N-methylpyrrolidone until the above X-ray diffraction pattern has been obtained. The pigment, prepared by grinding or acid-pasting, may be stirred or boiled with the N-methylpyrrolidone, or ground with a water-soluble inorganic salt, an alkali and the N-methylpyrrolidone. Examples are given. In further examples, (1) a printing ink is made by grinding the above linear quinacridone with aluminium hydroxide and a linseed oil varnish; and (II) a wallpaper colour is made by suspending heavy spar in aqueous aluminium sulphate, adding sodium carbonate and an aqueous paste of the above linear quinacridone and then aqueous barium chloride and mixing the resulting precipitate with an aqueous glue solution. Specifications 808,052 and 868,360 are referred to.ALSO:In an Example (13) on red dyed paper is made by mixing an aqueous paste of a linear quinacridone exhibiting in its X-ray diffraction pattern three strong lines at a double glancing angle of 6.5 degrees, 13.7 degrees and 26.4 degrees, three medium lines at 13.1 degrees, 13.3 degrees and 23.8 degrees and three weak lines at 17.0 degrees, 20.5 degrees and 25.0 degrees and having a mean primary particle size of more than 0.1 micron and a specific surface of less than about 30 square metres per gram with bleached sulphite cellulose, grinding the mixture with wood glue and aluminium oxysulphate and working up in a paper machine.

    Abstract: A pigment composition contains: (a) 30-70% by weight pigment of particle size 50 mm -1 m . (b) oil-soluble dispersing agent having "HLB-value" of 4-12, (c) water-soluble dispersing agent prepared by reacting 1 mole of a sulphonated phenol with 0,4-1,5 moles of urea and 0,6-2,2 moles of formaldehyde and treating product with 0,3-0,7 mole of a phenol and 0,-0,7 mole of formaldehyde. The ratio by weight of (b) to (c) may be 1:19-6:4, preferably 1:4-2:3, and there may also be present 0-5% of a wetting agent and/or protective colloid. Suitable pigments are copper phthalocyanine and chlorinated copper phthalocyanine; water-insoluble azo dyes, e.g. from 2,3-hydroxynaphthoic acid amides and aromatic diazo compounds; vat dyes, e.g. indigo and N,N1-dihydro-1,2, 21,11-anthroquinone-azine; TiO2, iron oxide and carbon black. The compound (b) is readily soluble in organic solvents and the solution is readily dispersed on shaking with water. Suitable compounds are prepared by reacting 1 mole of a long chain alcohol, a phenol, a long-chain amine, a long chain carboxylic acid or a long chain amide with 1-10 mole of ethylene and/or propylene oxide; other suitable compounds are dialkylsulphosuccinates, petroleum sulphonates, palmitic acid esters of sorbitol, and long-chain alcohols or acid amides. Particularly suitable for (c) are the products of Specification 890,150. Suitable wetting agents are: the sodium salt of sperm oil alcohol sulphuric acid ester, of 2-hydroxyoctadecane-1-sulphonic acid, or of dioctyl sulphosuccinate; the reaction product of oleic acid ethanolamide and 9 moles of ethylene oxide. Protective colloids include: maleic acidstyrene or -vinylmethyl ether copolymers; polyacrylic acid; polystyrene sulphonic acid; dextrin; and copolymers of acrylamide and methacrylamide. The compositions may be used in offset printing, for preparing aqueous paints, or for colouring paper, soaps, washing powders, or plastic dispersions. In the examples, such dispersions are used to colour: (1) polyvinyl propionate or polymethacrylic acid, (2) styrene (60 parts)-butadiene (40 parts) copolymer or polyvinyl propionate or poly methyl methacrylate or copolymers thereof, (3) and (5) as (1) and (2), using the dyes: (1) Heliogen blue B, (2) dye from diazotized 2-chloro-4-amino toluene 5-sulphonic acid and beta hydroxynaphthoic acid, (3) Indanthren blue RS, (4) Lithol red 2G (5) as (1). In Example 1, a little sodium polyacrylate is also present.

    Abstract: Highly concentrated, dust-free, solid and readily dispersible pigment formulations contain (a) from 70 to 95% by weight of one or more finely divided pigments, (b) from 5 to 30% by weight of one or more surfactants which possess 20-45% by weight of ethylene oxide units, have a mean molecular weight of from 4,000 to 15,000 and are obtained by reacting an amine of the formula where R is C2-C6-alkylene, R1 is H or C1-C4-alkyl and n is 1, 2, 3, 4 or 5, or R is 1,3-phenylene, 1,4-phenylene or 4,4'-diphenylenemethane, R1 is H and n is 1, with propylene oxide and then reacting the product with ethylene oxide, and (c) from 0 to 5% by weight of waxes and/or antifoams, with or without (d) other agents conventionally used in pigment formulations, the percentages being based on (a+b+c). The formulations are very useful for pigmenting aqueous, alcoholic or aqueous/alcoholic printing inks and surface coatings, and printing pastes for textiles.

    Abstract: New and valuable herbicide comprising 1-phenyl-4-amino-5-chloro (or -5-bromo)-pyridazone-(6) which contains from 10 to 65 weight % of the active ingredient in the form of an aqueous suspension and, as dispersant, a condensation product of sulfonated phenols free from condensed ring systems with urea and formaldehyde in a molar ratio of 1:1 to 1.5:1.7 to 2.2, which condensation product has been after-treated with phenols and formaldehyde. The dispersion is extremely stable, even after prolonged storage periods. It can be readily mixed with other plant protection agents upon dilution. No dust problems occur when the spray liquors are prepared for use.
