    Abstract: Compounds of the formula where A completes a benzene or naphthalene ring which may contain non-water-solubilizing substituents, R1 and R2 are H or non-water-solubilizin substituents and Me is Zn, Mn, Ni or Cd are incorporated in macromolecular substances and used in printing inks based on nitrocellulose. Examples describe the incorporation of pigment in polyvinyl chloride and polystyrene and the preparation of a printing ink by grinding the pigment with a mixture of nitrocellulose, dibutyl phthalate, ethyl alcohol and ethylene glycol.ALSO:The invention comprises compounds of the formulae where A completes a benzene or naphthalene ring which may contain non-water-solubilizing substituents, R1 and R2 are H or non-water-solubilizin substituents and Me is Zn, Mn, Ni or Cd. The compounds are prepared by reacting together compounds of the formulae to give the azamethine compound which may then be metallized by an agent which supplies Zn, Mn, Ni or Cd. The compounds may be used in the production of printing ink. Example 7 describes the preparation of printing inks by grinding the pigment with linseed oil varnish.

    Abstract: Styrene polymers, e.g. polystyrene, are mass coloured using a yellow dye of formula In an example 0.05% of the dye was kneaded with polystyrene at 200-280 DEG C., the composition was then cooled, ground in a mill to a particle size of 2-4 mm., and processed in an injection moulding machine at 220-300 DEG C. to give yellow mouldings.

    Abstract: An organic polymer used as a pigment is obtained by reacting at least one monomeric aromatic or cyclo-olefinic compound, consisting of either (a) hydrogen and carbon atoms or (b) a hetero atom contained in the nucleus of the aromatic compound and hydrogen and carbon atoms, with or without one or more linear olefins or diolefins consisting of hydrogen and carbon atoms, e.g. ethylene or butadiene, in the presence of a Friedel-Crafts catalyst and a dehydrogenating substance. Monomeric compounds exemplified are benzene, carbazole, thiophene, naphthalene, dicyclopentadiene, diisopropyl benzene, and allyl benzene. Friedel-Crafts catalysts exemplified are AlCl3, AlBr3, ZnCl2, BF3; other specified are FeCl3, SnCl2, SnCl4. Dehydrogenating agents exemplified are CuCl2, FeCl3, HgCl2, PbCl2, tetrachloroquinone; others specified are cobaltic, ceric and manganic salts, and oxygen. Compositions described incorporating the above pigments are: a printing ink based on a linseed oil varnish; a baking lacquer comprising also a coconut oil resin, a ureaformaldehyde resin and xylene; a polyvinyl chloride resin containing also diisooctyl phthalate and titanium dioxide; a water dispersible paste comprising water and a condensation product of sodium 2-naphthalene sulphonate and formaldehyde; and a wallpaper paint prepared by adding sodium carbonate to barytes and aluminium sulphate in water, adding the above water dispersible paste to the mixture followed by barium chloride solution, washing the precipitate so formed and mixing the resultant paste with glue solution.

    Abstract: 2,3- dihydrofuranes are produced by treating alkane-diols-1,4, having at least one primary or secondary hydroxy group, in the liquid phase at elevated temperature with a catalyst which contains cobalt metal. The preferred starting materials are butane-diols (1,4) which are substituted by alkyl radicals having up to 3 carbon atoms. The catalyst is preferably applied to a carrier, e.g., aluminium oxide, silica gel or aluminium phosphate, and may also contain activators which promote dehydrogenation and/or dehydration, e.g., zinc, manganese, copper, silver, palladium, chromium, phosphoric acid and acid phosphates. Preferably a supported catalyst contains 10-30% by weight of cobalt. If an activator is used it is preferably present in amounts of 0,1 to 10% by weight based on combined cobalt and carrier. The reaction is preferably carried out at 160 DEG -250 DEG C. In some cases it is advantageous to add a high-boiling carboxylic acid, e.g, caproic, caprylic, capric, lauric, palmitic or stearic acid. Examples are given of the conversion of butane-diol-1,4 to 2,3-dihydrofurane, 1-methyl-butane diol-1,4 to 2-methyl-2,3-dihydrofurane and 5-methyl-2,3-dihydrofurane, 1,4-dimethyl-butanediol-1,4 to 2,5-dimethyl-2,3-dihydrofurane, and 1,1-dimethyl-butanediol-1,4 to 2,2-dimethyl-2,3 dihydrofurane. Specification 678,468 is referred to.
