| 摘要 |
The present invention relates to an effect pigment comprising as a substrate a glass flake with a coating, said coating comprising at least one layer of at least one high refractive material, said material having a refractive index of at least 1.8, and/or at least one layer of at least one semitransparent metallic material, wherein said glass flakes comprising the following composition: 65-75 wt.-% silicon oxide, preferably SiO2-9 wt.-% aluminium oxide, preferably AIO0.0-5 wt.-% calcium oxide, preferably CaO 5-12 wt.-% sodium oxide, preferably NaO 8-15 wt.-% boron oxide, preferably BO0.1-5 wt.-% titanium oxide, preferably TiO0.0-5 wt.-% zirconium oxide, preferably ZrObased on the weight of said glass flakes. The invention relates also to a method for producing the effect pigments as well as to the use of said effect pigments. The invention further relates to coating formulations based on the effect pigments. |
