Multilayer black polyimide film and manufacturing method of the same |
| abstract |
The present invention relates to a black polyimide film having a multilayer structure having excellent alkali resistance and excellent optical and mechanical properties and a method for manufacturing the same. Based on the total weight of the black polyimide film having a layered multilayer structure, 45 to 85% by weight of the core layer, 10 to 40% by weight of the sum of the first skin layer and the second skin layer, and 5 to 15% by weight of the black pigment It is characterized in that it further comprises % by weight. |
