the carbon black according to the invention can be used in rubber plastic printing inks inks inkjet inks toners finishes paints paper bitumen concrete and other construction materials the carbon black according to the invention can be used as a reducing agent in metallurgy the carbon blacks according to the invention have the advantages that they form a stable dispersion low ph and at the same time have high purity low ash content and low 5 u03bcm sieve residue the high purity results in substantial advantages in use the low content of soluble substances low ash content permits the production of very stable dispersions for example aqueous or solvent containing dispersions for coating applications or inks this has advantages in production and storage the high stability of such dispersions permits an increase in the solids content which in turn has numerous advantages such as for example reduced production and transport costs the low content of insoluble particulate substances permits the production of films and finishes having few specks furthermore the abrasion of printing plates for example in newspaper printing is reduced with the result that the crispness of the printed image is maintained for longer in addition longer service lives of filters and strainer sieves are obtained for example in the production of ink formulations and plastics master batches the.
