Zusammenfassung:	Diskette-shaped multi-layer interference pigments (8) for colour effect paints used to lacquer consumer products, especially motor vehicle bodyworks, have the following construction: (A) at least one layer (14) comprises liquid crystal polymers (LCP) whose mesogens have an at least approximately chiral-nematic, smectic and/or cholesteric arrangement ; (B) a light-absorbent layer (11) absorbs at least some of the light within the visible spectrum; and (C) the circumferential sides of the diskettes are uncoated broken edges (12) of the diskette multi-layer composite (13). Also claimed are: (i) the preparation of these pigments; (ii) paints containing these pigments; and (iii) paints applied to consumer products, especially motor vehicle bodyworks, containing these pigments in the coloured layer.
