    Abstract: Cis-trans quinacridone is obtained by heating at 170 DEG C. in an o-dichlorobenzene medium and in presence of p-toluenesulphonic acid, N,N1-bis-diethylcarbamyl - 2,5 - dianilinoterephthalic acid dimethyl ester.ALSO:The invention comprises bis-(N-carbamyarylamino) benzene dicarboxylic acid dialkyl esters in which the arylamino groups, which are ortho to the ester groups, may be substituted by a nitro group or one or more alkyl or alkoxy groups or halogen atoms and the carbamyl radicals may be mono- or di-alkyl or aryl substituted; the compounds are made by heating esters of the bis-isourea ethers of the corresponding dihydroxy benzene dicarboxylic acids at 70-200 DEG C., e.g. as in the following reaction scheme in which R is C1- 4 alkyl, R1 is H o up to two nitro groups, halogen atoms or C1- 4 alkyl or alkoxy groups, R2 and R3 are C1- 4 alkyl, phenyl or naphthyl, or NR2R3 constitutes a 5- to 7-membered ring, while rings A and B are phenyl or naphthyl or are members of an aromatic-heterocyclic system, e.g. 9-methyl carbazyl. The starting materials (e.g. I) are obtained by reacting esters of hydroxy acids with arylimino carbamyl halides and are stated to be novel. Exemplified products are derivatives of bis-(arylamino) isophthalic acid (as in II), or of 2,5-bis-(arylamino) terephthalic acid.

    Abstract: A process for producing compounds of formula wherein the arylamino groups are in o-position to the carbalkoxy groups, Ar is phenyl or a polynuclear aryl radical which may be part of an aromatic heterocyclic system, R is a C1- 8 aliphat radical, R1 and R2 are H, halogen, nitro, alkyl or alkoxy and n is 1 or 2, comprises rearranging the bis(N-arylbenzimino ethers) of the corresponding dihydroxyphthalic acid esters* at 110-200 DEG C. The starting materials of the formula are made by reacting the disodium compounds of esters* with N-arylbenzimido chlorides.

    Abstract: New isoindoline derivs. are of formula (I) (in which R1 and R2 are methyl or ethyl.) Used for mass colouring of thermoplastics in red shades they give strong shades which are very stable to high temps., eg. up to 300 degrees C in polystyrene, in comparison with nearest cpd fromcondensn. of 1-amino 3-imino isoindolenine with 2 mols 2-cyano-methyl benzimidazole, which is only stable to 220 PC.

    Abstract: The invention comprises metal complex compounds of the formula wherein A represents a devalent radical which completes the portion of the molecule to from an aromtaic or heterocyclic ring which may be substituted, e.g. by arylazo groups, Z represents a halogen atom or a radical having the formula -X-R in which X is the bridging group -O-, -S- or -NHCO- and R is a C1-C4 alkyl radical or an aryl radical which may be substituted by alkyl groups, halogen atoms and/or a nitro group, and Me represents a metal of Group IIa or IIb of the Periodic Table or Cu, Pb, Mu, Fe, Ni or Co. They may be obtained by heating a solution or suspension of the appropriately substituted bisoxazole of the formula in a polar solvent or a mixture of polar solvents with non-polar solvents or in water, with a solution of the metal-supplying compound of the said type in the same solvent or in water or aqueous ammonia at temperatures of 50 DEG to 200 DEG C.; or by heating a suspension of the above bisoxazole in water with one of the metal-supplying agents, if desired under pressure. By using different metal ions mixed metal complexes may be obtained. Examples are given for the production of the compounds. They may be used as pigments in printing inks which also contain aluminium hydroxide and linseed oil varnish, distempers and lacquers. They may be used for pigmenting synthetic. semi-synthetic or natural macromolecular substances such as polyvinyl chloride, polystyrene, polyethylene, polyesters, phenoplasts, and aminoplasts (see Division C3).ALSO:Compounds of the formula wherein A represents a divalent radical which completes the portion of the molecule to form an aromatic or heterocyclic ring which may be substituted, Z represents a halogen atom or a radical having the formula -X-R in which X is the bridging group -O-, -S- or -NHCO- and R is a C1-C4 alkyl radical or an aryl radical which may bear alkyl groups, halogen atoms and/or a nitro group; are obtained by heating a 2,5-diaminobenzoquinone containing the Z radicals in 3,6-position in an organic solvent with about twice the molar amount of an aldehyde of the formula at temperatures of 130 DEG to 200 DEG C. Examples are given for the production of these compounds. They are useful as intermediates in the preparation of pigments (see Division C4).ALSO:Synthetic, semisynthetic or natural macromolecular substances, such as polyvinyl chloride, polystyrene, polyethylene, polyesters, phenoplasts, aminoplasts, polyurethane fibres, and rubber are pigmented with a metal complex of the formula wherein A represents a divalent radical which completes the portion of the molecule to form an aromatic or heterocyclic ring which may be substituted, Z represents a halogen atom or a radical of the formula -XR in which X is the bridging group -O-, -S- or -NHCO- and R is a C1-C4 alkyl radical or an aryl radical which may bear alkyl groups, halogen atoms and/or a nitro group, and Me represents a metal of Group IIa or IIb of the Periodic Table or Cu, Pb, Mn, Fe, Ni or Co (see Division C2). Examples are given in which (a) a mixture of polyvinyl chloride, dibutyl phthalate and titanium dioxide is coloured, and (b) pigments are ground with a stoving lacquer consisting of coconut alkyd resin, urea-formaldehyde resin, xylene and n-butanol.
