    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. Specified compositions include pigment pastes and powders, printing colours, distempers and lacquers. 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% of chlorine) and the preparation of its a - and b -crystal forms is described. 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 ligrin sulphonates. Specified oil-soluble emulsifying agents are dodecyl, oleyl, stearyl and sperm oil alcohols; dodecylphenol, octylnaphthol; oleylamine, stearylamine and 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, styrene-divinyl-benzene and styrene-butadiene copolymers. In examples: (1) the a -form of C.I. Vat Violet 9 is prepared and acid pasted, the water used to precipitate the pigment containing dodecyl alcohol, and the pigment so prepared is ground with aluminium hydroxide and linseed oil varnish and blended with linseed oil and zinc white to give an oil paint; (2) the a -form of the pigment prepared in (1) is pasted with nitrobenzene and the nitrobenzene steam-distilled to give the b -form which is ground into a stoving lacquer comprising coconut oil alkyd resin, urea-formaldehyde resin, xylene and n-butanol; (3) the a -form of C.I. Vat Violet 9 is acid pasted and added with powerful stirring to a mixture of water, white spirit and the condensation product of 4 moles of ethylene oxide with 1 mole of sperm oil alcohol and the precipitated pigment, which is of the b -form, is ground with a solution of nitrocellulose, dibutyl phthalate, butylbenzyl phthalate, a condensation product from cyclohexanone and methy-cyclohexanone, butyl acetate, ethyl acetate and toluene to give a lacquer which may also contain titanium dioxide. Further methods of preparing the preferred pigment in the b -form are described. Specifications 276,518, 315,276, 325,525, 329,263 and 340,264 are referred to.

    Abstract: Masses and mixtures are pigmented with N,N1-dimethyl-3,4,9,10-perylenetetracarboxylic acid di-imide. The mean primary pigment particle size in the direction of the greatest dimension may be 0,05-5 microns, preferably 0,3-2 microns and 0,05-0,5 microns. The masses and mixtures may also contain partly or wholly oil-soluble emulsifying agents or insoluble solid or other protective colloids and also watersoluble dispersing agents. The mixtures or masses may be flushing pastes, printing colours, distempers, binder colours or lakes; surface coating materials such as the physically, oxidatively or catalyst hardening types; and also powders such as organic or inorganic pigments, e.g. titanium dioxide, barium sulphate, calcium carbonate or talc, rock flour, cements, gypsum, starch and wood flour. Many emulsifying and dispersing agents are specified and examples are given. Specification 26690/13 and Specifications 201,786, 837,326, 839,634 and 886,932 are referred to.ALSO:Masses and mixtures are pigmented with N, N1-dimethyl-3, 4, 9, 10-perylenetracarboxylic acid di-imide.
