    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: The invention comprises pigment-coloured compositions or mixtures characterized by a content of a bromine-containing compound of the dibenzanthrone and/or isodibenzanthrone series in the form of a preparation with up to 20%, with reference to the dye of a partly or completely oil-soluble emulsifier or an insoluble solid colloid or other protective colloid. Specified compositions include articles of polyvinyl chloride, polystyrene, polyethylene, polyesters, phenoplasts and aminoplasts. The preferred dye is the compound known as C.I. Vat Violet 9 (i.e. an isodibenzanthrone containing 13-17% bromine and up to 1% chlorine). The compositions may also contain up to 1% by weight of the dye of a water-soluble dispersing agent such as alkyl and aralkyl sulphonates, ethylene oxide condensation products and sodium lignin sulphonates. Specified oil-soluble emulsifying agents are dodecyl, oleyl, stearyl and sperm oil alcohols; dodecylphenol, octylnaphthol; oleylamine, stearylamine, coconut oil amine; stearic, lauric and abietic acids; triethanolamine mono-oleate or -stearate; oleic acid ethanolamide; the addition products of ethylene oxide with oleic acid or sperm oil alcohol; petroleum sulphonates and dialkyl sulphosuccinates. Specified protective colloids include aluminium hydroxide, silica gel, silicones, silicic acid esters, alkyd resins, styrenedivinylbenzene and styrene butadiene copolymers. In an example the p-modification of C.I. Vat Violet 9 admixed with 5-10% of an ethylene-oxide-oleic acid condensate is used to colour a mixture of polyvinyl chloride, di-isooctyl phthalate and titaniumdioxide in a violet shade. Specifications 276,518, 315,276, 325,525, 329,263 and 340,264 are referred to.ALSO:The invention comprises pigment-coloured compositions or mixtures characterized by a content of a bromine-containing compound of the dibenzanthrone and/or isodibenzanthrone series in the form of a preparation with up to 20%, with reference to the dye, of a partly or completely oil-soluble emulsifier or an insoluble solid colloid or other protective colloid.
