Product 1

HCID 13976Quinacridone

Procedure

The procedure of Example 8 is repeated, but using 4 g of the aqueous presscake of the nanosize 2,9-dimethylquinacridone/naphthalene sulfonic acid formaldehyde polymer mixture according to Example 2 instead of 7 g of the aqueous presscake of the nanosize quinacridone/naphthalene sulfonic acid formaldehyde polymer mixture presscake according to Example 1. A violet beta quinacridone pigment of similar good pigment properties is obtained.
