Abstract (en)

[origin: DE19638797A1] A process for producing pigment particles of defined shape and size is characterised in that a flat structure with holes of defined shape and size is treated with a polymerisable substance or mixtures of substances in such a way that the holes are filled, any solvents are removed, the substance or mixture of substances is polymerised and the thus formed pigment particles are removed from the holes. The shape and size of the thus produced pigments may be easily varied by selecting appropriate substrate parameters. They are suitable for the known uses of such substances, in particular in lacquers, paints and printing inks.
