Abstract
A composition containing an organic pigment, the particles of which pigment are provided with a tenacious, dense, highly crosslinked coating of ethyl cellulose. Pigment compositions of this kind are distinguished in particular by their color strength, by their excellent rheological properties in varnish and printing ink systems, by the high gloss of the finishes obtained therewith, and by the substantial non-deformation of the plastic mouldings pigmented therewith.
