More Information
Summary:The present invention relates to novel pigment mixtures, comprising two different components A and B, wherein component A is a graphite in the form of platelets (graphite nanoplatelets), which have an average particle size of below 50 microns and a thickness below 100 nm, and component B is an organic, or inorganic pigment. The use of graphite nanoplatelets in a pigment mixture with organic and/or inorganic pigments, especially effect pigments (component B), allows the preparation of metallic like colorations with a maximal opacity (background substrate disappears totally) while keeping a good rheological behaviour (low concentration use). Cette invention concerne de nouveaux mélanges de pigments, comprenant deux composants A et B différents. Le composant A est un graphite sous forme de plaquettes (nanoplaquettes de graphite) qui ont une taille de particules moyenne inférieure à 50 microns et une épaisseur inférieure à 100 nm, et le composant B est un pigment organique, ou inorganique. L'utilisation de nanoplaquettes de graphite dans un mélange de pigments avec des pigments organiques et/ou inorganiques, notamment, des pigments d'effet (composant B), permet de préparer des colorations du type métallique ayant une opacité maximale (le substrat de fond disparaît complètement) tout en conservant un bon comportement rhéologique (utilisation à basse concentration).
