Abstract
Official abstract text for this publication.
A metallic effect pigment comprising at least three layers: A) a layer A which comprises at least one metal M A and has an average oxygen content O A , based on the total amount of M A and O A in the layer A, B) a layer B comprising at least one metal M B and having an average oxygen content O B of 0 to 77 atom %, more particularly of 0 to 58 atom %, based on the total amount of M B and O B in the layer B, C) a layer C which comprises at least one metal M C and has an average oxygen content O C , based on the total amount of M C and O C in the layer C, the average oxygen content O AC in layers A and C being determined in accordance with the formula (I) O AC = 1 2 ( O A M A + O A + O C M C + O C ) ( I ) and being situated within a range from 2 to 77 atom %, more particularly from 25 to 58 atom %. The disclosure further relates to processes for preparing this effect pigment and also to its use.
