Procedure

14.8 g of crude β-copper phthalocyanine, 0.2 g of 8-hydroxymethyltricyclo[5.2.1.02,6 ]decane [TCD alcohol M®, ex Hoechst], 125 g of water and 400 g of glass beads with a diameter of 3.5-4.0 mm are ground for 15 hours at 320 rpm, with water cooling, in a 500 ml glass bead mill of 8 cm diameter. The pigment suspension is separated from the glass beads, which are washed with water. The suspension is then filtered and the filter cake is dried at 70°-80° C. in a vacuum drying cabinet, affording 13.5 g of blue copper phthalocyanine pigment which, when incorporated in powder form into varnishes, gives strong finishes.
