Coating material, esp. coating powder, esp. for painting car bodies, is claimed (I), contg. several paint substances with different affinity parameters, multilayer parameters and surface tensions with regard to air and substrate surface, which separate automatically after application to the substrate so as to form a series of layers defined by the values of the above parameters etc. The special features of (I) are: (a) a layer next to the substrate contains absorptive colour pigments, (b) the paint in the separating layers contains, as additional or sole pigment, interference pigments based on liq. crystalline side chain polymers (LCP), in the form of flakes which become automatically oriented in the layer structure so as to lie approx. parallel to the substrate surface, (c) the colour pigments in the lower layer are black or of the same shade as that of the colour-defining interference pigments in the other layers. |
