Abstract

The use of an azo pigment of the formula (1), as a colorant in electrophotographic toners and developers, powders and powder coatings and in electret materials, wherein the azo pigment powder has a specific surface area of more than 70 m<SP>2</SP>/g and wherein the azo pigment particles have a length-to-width ratio of on average less than 2.8:1 and a mean particle size d50 of less than 130 nm.
