Abstract:
The invention relates to a pigment composition that is composed of compounds of formulas (I), (II) and (III), is characterized by a average particle size d50 ranging from 10 to 60 nm, less than 5% by volume of the particles being greater than 70 nm, and can be obtained by reacting of 1 mol of a succinic acid diester with 2 mol of a mixture of nitriles A-CN and B-CN nitriles, the molar ratio of A-CN and B-CN in the nitrile mixture being in the range from 99.5:0.5 to 85.0:15.
