Multilayer black polyimide film and manufacturing method of the same |
| abstract |
The present invention relates to a multi-layered black polyimide film having excellent alkali resistance and excellent optical and mechanical properties, and a manufacturing method thereof. The black polyimide film of the present invention comprises a first skin layer and a second skin layer around a core layer. Based on the total weight of the layered multilayered black polyimide film, 45 to 85% by weight of the core layer and 10 to 40% by weight of the sum of the first and second skin layers, and 5 to 15 black pigments It characterized in that it contains more weight percent. |
