    Abstract: Coatings which in organic binders contain (a) a plateletlike copper phthalocyanine pigment of the beta -modification which contains at least 50% by weight of platelets which are at least 10 mu m in length and at least 3 mu m in width and where the ratio of length to width is within the range from 3.3:1 to 1:1 and (b) at least one different pigment or pigmentary (crystal) form. The novel coatings give novel colouristic effects. The colours change their hue with a change in the viewing angle. Very coarsely divided (a) gives metallic effects very similar to those obtainable with aluminium platelets.
