摘要
The present invention relates to a polyamic acid resin composition, which is characterized by containing nanolayer silica sheet and/or nanometer silica powder. The present invention also relates to a polyimide film prepared from the composition, the resultant film exhibits improved dimension stability, low water-absorbability, high transparency, and low Coefficient of Thermal Expansion (CTE) value and is suitable used in flexible print wiring board and wiring board for liquid crystal display (LCD).
