Abstract

See full text

An aqueous writing, marking and/or drawing liquid is configured for capillary systems, more particularly for applicator implements having a capillary system. The liquid has a viscosity of less than 50 mPas, more particularly less than 20 mPas (Brookfield, 20° C., cone-plate CPE-40). The liquid contains a wetting agent, graphite having a carbon content of between 95 and 99.9 wt %, an ash content of between 0.1 and 5 wt %, and a particle size ≤20 μm at D90, and at least one release agent, more particularly in a concentration of 2 to 15 wt %. The release agent contains barium sulfate and/or an aqueous, highly mobile, nonsedimenting colloidal dispersion of nanoparticulate silicon dioxide particles.
