Abstract (en)

[origin: WO2022234023A1] The invention relates to a biogenic black pigment with a 14C content of greater than 0.20 Bq/g carbon and less than 0.45 Bq/g carbon, a mass fraction of volatile components of 20 Ma.% to 40 Ma.% determined according to DIN 51720 and in relation to the dry matter of the pigment, a mass fraction of carbon of 60 Ma.% to 95 Ma.% determined according to DIN 51732 and in relation to the dry matter of the pigment, an ash content of 0.5 Ma.% to 7 Ma.% in relation to the dry matter of the pigment, a mass fraction of polycyclic aromatic hydrocarbons (PAH) of <10 ppm in relation to the dry matter of the pigment, and a mass fraction of lead, mercury, cadmium and chromium of <100 ppm in total, in relation to the dry matter of the pigment, an STSA of 5 m²/g to 200 m²/g and a D99 value of the Q3 cumulative curve distribution of the particle size of ≤100 μm. The invention also relates to: a method for the production of the biogenic black pigment; the use of the biogenic black pigment for the achromatic coloring and chromatic shading of plastics, plastic parts, coating materials, printing colors, inks, paints, papers, paperboards, cardboards and mineral materials, and as a reinforcing filler for rubber-like, thermoplastic, liquid crystal and magnetorheological elastomers; as well as materials and objects containing the biogenic black pigments.
