| 摘要 |
The present invention relates to an effect pigment comprising as a substrate a glass flakes 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, wherein said glass flakes comprising the following composition:
50 - 65 wt.-% silicium oxide
10 -18 wt.-% aluminium oxide
10 - 28 wt.-% calcium oxide
0.05 - 15 wt.-% titanium oxide, based 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 the use of glass flakes having a content of titanium oxide as a substrate for effect pigments. |
