Conclusions from Tests on Pigment Concentrates for Different Lacquer Systems:

(76) The amine adducts according to the invention are characterized by particularly good compatibility in the various lacquer systems. Corresponding pigment pastes have low viscosities and can be incorporated excellently. It is possible without further effort to produce pigment pastes with higher pigment contents. The outstandingly good luster and the excellent shelf life of the pigment concentrates are particularly noteworthy.
