Abstract (en)
[origin: WO2006005408A1] The invention relates to novel crystalline modifications (eta, theta, jota, kappa) of the C.I. Pigment Yellow 181, obtained when one of the known phases or another inventive phase of said pigment is treated with specific solvents. The novel crystalline phases are characterised by yellow shades and excellent colouring properties.
