Abstract: The dyes are of formula (I) (in which R1 and R2 are H, Cl, Br, NO2, CN, OH, amino-alkylamino with (1-4)C, phenyl, (1-4)C alkyl, (1-4)C alkoxy, (2-4)C hydroxyalkoxy or carbalkoxy, and X is H, Cl, Br, NO2 or R3 and R4 are the same as R1 and R2. Pref. R2 is H, R1 is H, Cl, Br, ethyl, methoxy or ethoxy X is H, Cl, Br or R3 is a R1 and R4 as R2. The dyes are made by reacting mono- or di-halogen azabenzthones with opt. substd. thiophenols in org. solvent in presence of an acid acceptor and opt. a catalyst. They are suitable for dyeing linear polyester fibres in strong brilliant greenish-yellow shades with good fastness and for colouring thermoplastics in strong fluorescent yellow shades.

Abstract: The raw materials are mineral oil-carbon black suspensions formed in the splitting of hydrocarbons with air or oxygen by the submerged flame process, where they separate out on quenching the gas stream. Low-boiling hydrocarbons with unpleasant swell and detrimental to printing inks are pref. removed from the suspensions by stripping the hot product from the flame process with inert gases or by application of vacuum. The black obtained is weakly agglomerated and can be easily processed to printing ink pastes with optimum pigment dispersion by simple and fast dispersion methods.

Abstract: Title cpds have the formula (I): (where R1 and R2 are H, Cl, Br, 1-4C alkyl or alkoxy, or carboalkoxy with a total of 2-4C atoms, R3 is H, Cl Br or NO2, R1 and R2 are the same or different). They are prepd. by heating the diazonium salt of Bz-1-(2'-aminophenylmercapto)-azabenzanthrone in the presence of Cu, Cu cpds. or their mixts.
