The invention relates to metallic effect pigment, the metallic effect pigment having at least one diffractive structure and at least one layer which comprises metal nanoparticles and metal oxide phase, the metal of the metal oxide phase and the metal of the metal nanoparticles in this at least one layer being identical. The invention further relates to a process for preparing these metallic effect pigments, to a coating composition, and to a coated article.

PVD-metallic effect pigments with diffractive structure and metal nanoparticles, process for preparing them and use thereof

A metallic effect pigment comprising at least three layers: 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.

Multi-layer metallic effect pigments, process for their preparation and use

The invention relates to a metallic effect pigment, which metallic effect pigment has a substantially homogeneous chemical composition comprising at least one metal M and having an average content of oxygen of from 25 to 58 atomic percent, based on the total content of M and oxygen. The invention further relates to a method for the production of said metallic effect pigment.

Dark metal effect pigments produced by means of a physical vapour deposition (PVD) method

A platelet-shaped PVD metallic effect pigment having first and second outer faces, the platelet-shaped PVD metallic effect pigment having at least one PVD layer, the at least one PVD layer including elemental metal with clusters of elemental metal and metal oxide. The amounts of elemental metal in the first outer face and in the second outer face of the PVD metallic effect pigment are different from one another and they differ by at least 10 atom %. The disclosure further relates to a method for producing these platelet-shaped PVD metallic effect pigments, and to their use.

PVD metal effect pigment having gradient on nanoscale metal particles, method for the production thereof and use thereof

Platelet-shaped, copper-containing, metallic effect pigments which have a copper content of 60% to 100% by weight, based on the total metal content, the metal pigments having a thickness distribution as determined via thickness counting by scanning electron microscopy (SEM) and represented as cumulative undersize distribution,

Platelet-shaped, copper-containing, metallic effect pigments, process for preparing them and use thereof

The present invention relates to highly lustrous gold-colored metal effect pigments comprising a copper-based alloy and additional metallic alloy components, preferably zinc, and which are produced by means of stripping and comminuting metal films deposited in vacuo.

Copper-based metal flakes, in particular comprising zinc and method for production thereof
