摘要:
An interference pigment comprising a low-refractive-index, transparent, flake substrate coated with a high-refractive-index coating containing titanium (IV) oxide having a layer thickness of 20-200 nm and optionally further coated with an outer protective layer, is new. An independent claim is also included for producing an interference pigments comprising coating the substrate by a wet-chemical method by hydrolytic decomposition of a titanium metal salt in aqueous medium or by thermal decomposition by chemical vapor deposition or plasma vapor deposition process.
