    摘要: A process for preparing a mixed aluminium-heavy metal dyestuff complex, in which the amount of heavy metal present is 10-98% and that of aluminium is 2 to 90% comprising i) reacting the metal free dyestuff with less than a stoichiometric amount of a heavy metal compound followed by ii) reacting the product with an aluminium compound in an amount to produce a stoichiometric excess of metal (calculated on all the metal present) to form a mixed aluminium-heavy metal complex.

    摘要: This invention relates to coppered azo dyestuffs containing an alkyl-, aryl or alkoxyalkyl sulfamyl group on one moiety of the molecule and an alkyl-, aryl or alkoxyalkyl ammonium sulfonate or carboxylate group on the other moiety. The invention also relates to various intermediates, to compositions and to processes for preparing the metalized dyestuffs. The compounds are particularly suited for the application in laquers, ink-jet inks and electrographic toners.

    摘要: The invention relates to a process for the preparation of a purified version of a solvent-soluble dyestuff, comprising the steps of (a) mixing an aqueous presscake of the dyestuff into a water-miscible liquid; and (b) distilling off the water until a water content of 5% by weight maximum is attained; and (c) filtering the dyestuff composition comprising solvent-soluble dyestuff and water-miscible liquid, thereby removing all insoluble contaminants and (d) diluting the dyestuff composition comprising solvent-soluble dyestuff and water-miscible organic solvent in de-ionized water, thereby performing the precipitation of the solvent-soluble dyestuff which is then isolated after filtration and washing with de-ionized water This ink jet grade version has the important advantage of being virtually salt-free and solvent-free.
