  • Publication number: 20150110709
    Abstract: A method for producing a nanoparticle to separate a diketopyrrolopyrrole pigment includes separating an ?-type diketopyrrolopyrrole pigment nanoparticle having high crystallinity by carrying out separation of the diketopyrrolopyrrole pigment and crystal type transformation to the ?-type with substantially a single step. The ?-type diketopyrrolopyrrole pigment nanoparticle is separated by mixing a diketopyrrolopyrrole pigment solution having the diketopyrrolopyrrole pigment dissolved in a solvent and an alcohol solvent containing an alcohol compound solvent in a thin film fluid formed between at least two processing surfaces 1 and 2 arranged to be opposite to each other so as to be able to approach to and separate from each other, at least one of which rotates relative to the other. An acidic substance is contained in at least any one of the diketopyrrolopyrrole pigment solution and the alcohol solvent at this moment.

  • Patent number: 5416263
    Abstract: 4,4'-Diamino-1,1'-dianthraquinonyl compounds which are obtained in a known manner and which are easy to agglomerate or aggregate owing mainly to their too fine particle size are conditioned by heating an aqueous suspension consisting essentially of the 4,4'-diamino-1,1'-dianthraquinonyl compound and water in the presence or absence of a mineral acid or an alkali. The thus obtained 4,4'-diamino-1,1'-dianthraquinonyl pigments are used in paints, printing inks, coloring of plastics and the like. The aqueous suspension is preferably prepared by desulfonating a 4,4'-diamino-1,1'-dianthraquinonyl-3,3'-disulfonic acid compound in a mineral acid such as sulfuric acid and then mixing the desulfonation reaction mixture with water or by once isolating the resulting 4,4'-diamino-1,1'-dianthraquinonyl compound and mixing the isolated compound with water.
