The procedure of Example 6 is repeated, replacing the β-copper phthalocyanine pigment by 14.2 g of the azo pigment, C.I. Pigment Red 166, obtained direct from the synthesis and 0.8 g of 8-hydroxymethyltricyclo[5.2.1.02,6 ]decane [TCD alcohol M®, ex Hoechst] and grinding for 15 instead of 4 hours, to give a high yield azo pigment of the same structure which can be very readily incorporated in plastics and varnishes.
