ABSTRACT:
The invention provides a process for preparing uncoated, readily dispersible C.I. Pigment Red 112 by azo coupling in a microreactor, which comprises precipitating the coupling component in an upstream microreactor and coupling the precipitated coupling component in finely divided form to the diazo component in a microreactor.The C.I. Pigment Red 112 of the invention features low dispersion harshness in alkyd resin varnish, and a PCB content of below 25 ppm.
